Three sweet Charge Mixer customisations - including Crud Raceguards

The stock Charge Mixer is a great ride out of the box but there's always room for some improvements. Here's three customisations that make the bike quicker, nimbler and more practical: smaller diameter tyres, a shorter handlebar and Crud Roadracer mudguards

Speed - fit smaller diameter tyres

The 700*32 Conti Sportcontact tyres fitted by Charge are a good compromise between comfort and speed. However with the steel frame providing a bit of give  you can fit smaller diameter tyres, decreasing rolling resistance and gaining a few mph for free without making the ride unpleasantly stiff. 

What will fit? Alexrims who make the wheels think anything from 700-28 up to 700*35, but Sheldon thinks 700*25 will work safely too. I went for Conti 700*25 Gatorskins after a rather vague email from Alexrims where (paraphrased) they said you can try 700*25 but 700*28 is what they ultimately recommend. 

If you find it difficult deciding on a tyre the consensus seems to be that gatorskins are roughly on par with armadillos (only in 700*23 & 700*28) for toughness but Marathon Plus trumps all when it comes to stopping glass from getting to your tubes. 

Whilst on tubes don't forget to buy smaller diameter inners with the tyres if you go less than 700*28 - the stock conti tubes fit 700*28-700*32. 

Agility - fit shorter bars

I find it a little odd that the Mixer comes with bars of comparative width - they aren't the best for mixing it up with the traffic. Fortunately you can now buy the bar fitted to the Charge Plug Griffin, named "The Straw"  for a mere £20 which trims a whopping 14cm off the total bar width. 

To fit The Straw you'll need remove the rubber grips first (twist them off, put some effort into it!) then remove each piece of hardware taking care not damage, twist or kink any of the cabling as you do so. 

To make it easier I taped The Straw to the stem to hold it steady then slid on each piece of hardware as it came off the old bar. 

Once free of hardware loosen the bar clamp and slide out the old bar. You'll need to remove the bar clamp to insert the The Straw - it's tricky with only two hands to get the bar clamp off whilst holding the new bar, so if there's anyone about to help you now is the time to grab them. 

Once fitted push and twist the rubber grips back on to the bar. If you like the silver bullet bar ends you can probably trim the ends of the stock grips off so that they aren't covered, but I left mine in one piece for now. 

With the grips on you'll have to adjust the positions of the hardware to suit. Time to get friendly with your allen key - if you are anything like me and feel the need for a speedo and two headlamps the cockpit may look a little cluttered.

Getting the bar ends back on can be challenging - I cheated and rubbed a small amount of cooking oil on the bars to make life easier. Your mileage may vary.

Practicality - fit Crud Roadracer Mudguards

Savvy Mr. Crud figured out that after market mudguards not only add weight but also spoil the look of any ride they are attached to. So he developed the Roadracer Mudguards - streamlined, ultralight and, for guards, quite aesthetically pleasing. 

These are designed for sports roadbikes so fitting them to the Mixer can be a bit of challenge, especially if you are using the stock conti tyres. It can be done, however.

The Mixer uses discs rather than callipers so some bodging is required to get the guards working nicely. 

The tie-wrap that holds the front end of each guard above the wheel is designed to hang from a calliper mounting screw. No callipers, so no screw. No problem though - even though the callipers don't exist the mounting point does, so you can either buy a bolt and hang the tie-wrap from that, or as I did, run a tie-wrap through the mounting point and hang the guard tie-wrap from that. 

Yes, two tie-wraps - as I said, a bodge. But it works. 

Mounting the front guard is harder than the rear as the mass of the front disc mount sits exactly where the guard mounts are supposed to be attached. This means placing the mounts higher up the fork. It doesn't seem to affect the guards performance though - just looks a little odd. 

Remember to put some tape around the frame where the guard mounts are placed if you want to protect your finish. 

That's it - these three simple tweaks makes The Mixer feel like a more agile, sporty beast - more muscle car and less less tank like. And you won't have to worry about getting a wet bum next time you get caught out in a downpour. 

Do you have any customisations you'd like to share?

First impressions of the Large Rapha Cycling Backpack

Great looking, functional backpack from Rapha. Good capacity, well thought through internal design and waterproofing good but not perfect when fully loaded.  Not cheap, but should last, so as with most Rapha products: just about worth it.

First impressions of the Large Rapha Cycling Backpack

When cycling you don't want to be carrying a backpack. General use backpacks just don't work, and cycling specific products have the right features but  look like they were designed by the intern let loose in the crayon cupboard. The excepted wisdom is that if you need a 'pack, you actually need panniers. But once off the bike panniers just don't function as a general use bag, and who wants to sully the clean lines of their commuter with a pannier rack?

Enter the Large Rapha Backpack. Their objective was to design a cycling specific backpack that you could take to client pitch meeting and the mismatch between it and your Paul Smith suit wouldn't instantly rule you out of the job.

For all intents and purposes the 'pack looks like a laptop specific, practical every day use backpack. At forty five cm tall, thirty wide and twelve deep it cuts a low rectangular profile and you wonder how Rapha could label it "large". It's relative of course - it's the larger sibling of their original and somewhat smaller Rapha backpack.

Coming only in black, unless you are aware of the brand it's tricky to spot who made it - the trademark Rapha pink is used for two tiny stitching sections on the pack's rear, and their logo is subtly embossed onto the face of the bag. Huge strips of reflective don't feature; instead Rapha have opted for hundreds of tiny pin point reflective dots. These look grey in daylight and actually improve the aesthetic of the 'pack.

All in all, it looks great - just as a 'pack designed by Rapha should - modern with a touch of class. Yes, I said that about backpack.

Features & capacity
The 'pack features a main section that opens out like a clam shell to reveal two pouches and several sleeves: one for shirts, one padded laptop sleeve and a general sleeve that can take a camelback-like reservoir piped out through a covered hole in the top of the 'pack. A pair of elasticated straps feature to hold a pump, although they didn't suit my rather large Specialised AIr Tool. If you have a smaller mini pump they should work fine.

The main section of the bag will happily take a laptop a shirt, a pair of trousers, a New York Kryptonite Lock and cable, sunglasses and tools. Those with fifteen inch laptops will be disappointed; the 13" MacBook fits snugly but you won't fit anything bigger.

On the face of the bag are two deep pouches designed for wallets and hidden beneath them an extra fold out section designed for footwear. Cycling shoes, casual and smart shoes seem happy in the pouch, but forget about getting those Jeffery West boots in there.

Straps and fittings
Keeping the 'pack securely attached to your back are two main straps, a removable cross strap and waist strap. The cross strap feels heavy duty whilst the clip on the waist strap seems lightweight. I've not seen this kind of clip before so it will have to prove itself in use. All in all the array of straps offer increasing levels of security as the weight of  your luggage rises. The 'pack is sold as waterproof - the main pouches feature a rubber seal designed to keep the water out. The downside is that occasionally they foul the zip. Possibly a price worth paying for waterproofing. Capacity is good whilst the profile is low, the fixings seem genuinely serious and the design subtly attractive.

How is it to ride with?

Riding with the backpack

Comfort
The demands of a cycling specific back pack are slightly different to those of a day sack. When over the bars, the back curves outwards behind you meaning the surface the pack rests on will be convex. Additionally the slope of the back will distribute the weight over your back as opposed to walking when the pack hangs from your shoulders. This requires a different approach to padding - less on the straps and more on the back surface of the pack, but not all of it down the centre.

It would be criminal if Rapha hadn't recognised this but they have, and the back of the pack features generous padding that distributes its weight nicely whilst the straps are kept wide and thin.

Visibility
A further cycling specific feature is ensuring the design of the pack doesn't limit rear visibility. Some dedicated cycling packs feature a tall, narrow and deep profile to ensure when looking behind the rider doesn't just get a view of their 'pack. Rapha take the opposite approach keeping their pack tall thin and shallow, so that the rider looks over their pack rather than around it. Visibility is good with the main section is loaded. However when the shoe section is used some visibility is lost which at first is a little disconcerting. When using the shoe section you must remember to curve your neck to a greater degree to get full visibility - not a show stopper but something to bear in mind.

Resiliance
Rides with the 'pack have so far been limited to ten mile commutes in dry and torrential rain conditions. The pack has remained comfortable despite on occasion having around 7Kg in luggage and the pack doesn't seem to be too stressed when carrying a heavy item like a laptop and lock combo. This is confidence inspiring. So far so good.

In rain, the contents of the pack for the most part has remained dry, except items kept in the reservoir pocket;  papers kept loose in this pocket became slightly damp at one corner in torrential rain with a fully loaded 7Kg pack over a thirty minute ride. On reflection that isn't a bad performance but Rapha may need to do some additional testing and tweaks to make sure the bag is better sealed in nasty conditions with large loads.

As a side note, the pack makes an excellent day trekking pack, and was used on as a day sack whilst trekking in the Atlas Mountains. From this you can infer that longer rides with the pack should be comfortable, and this theory will be put to the test on the annual London to Brighton ride next week (June 20th).

Overall then

With the Large Backpack Rapha have produced a great looking, comfortable, practical cycling specific back-pack that will get your kit to work and back safely and should remain comfortable over longer rides. As with all Rapha kit, it will leave a hole in your wallet that may leave slightly uncomfortable - after all there are many cheaper 'packs. None of these will offer you the combination of aesthetics and practicality that the Large Backpack will however - It's not perfect as there are slight issues with over the shoulder visibility and water resistance, but other manufacturers haven't been able to get so much right with a bag that you can bring into the office and leave on full display rather than bury under your desk with the Lycra.

Objectively a good product that could be made great with a few tweaks. Relatively: exceptional in its class.

Weird Nokia E51 Mac Isync / Ical behavior

Just noting this down in case anyone else ends up tearing their hair out like me wondering why events are disappearing on their Isync paired Nokia phones.

With a standard Nokia / Isync bluetooth pairing:

  • Create an event using your E51 (other symbian phones may have the same issue) a while in the future, say in three months time
  • Sync it to Ical using Isync
  • Sync again
  • Now check your phone - where's the event gone?
Why is this happening? Who is deleting the events from your phone?

Well, seems by default the Nokia Isync plug-in only syncs events one month in the future. Fine. But on the next sync, Isync will delete any events a month outside the one month window from your phone regardless as to whether they originated on your phone or Ical. In other words, syncing a Nokia e51 with Isync will eventually delete all events outside the one month window except, confusingly, recurring events.  

To fix this, click the icon that represents your phone on the Isync window to reveal the Isync settings. Click "more options" then set the "Don't synchronize events after one year" drop down to "One Year". Or just un-check the option.

Charge Mixer - 500 mile detailed review

Bomb proof urban commuter with razor sharp track inspired looks and top-notch components. Comfortable, tough steel frame combined with Shinmano's Alfine internally geared hub gives an exceptionally precise and assured ride. Downside is the weight (~16Kg).

Pros:
  •  Quick and tough
  •  Lag free transmission
  •  Stationary up-shift/down shift
  • Eats up potholes with no fuss
  • Shimano discs provide ample stopping power and are straight forward to service

Cons:

  • 70s style frame and componentry means weight. Medium bike around 16Kg.
  • Removing rear wheel for servicing is a pain the first time.

What you get
At just shy of a grand you should expect a lot of bike. What you get is a sharp looking tange steel frame and fork matched up with Shimano's Alfine eight speed internally geared hub, Alex Rim's DP17s 700c wheels, Continental SportContact rubber and Shimano disc brakes. An eccentric bottom bracket provides chain tension adjustment - a meaty assembly that looks slightly at odds with retro skinny-ish steel tubing and track geometry. Charge provides the seat and stem; make sure you get the stem flipped if you want a more upright commuter stance.

Fixings for bottles and luggage racks are provided; some production runs omit the bottle mounts however so check when you buy.

The ride
If you are moving from a hard-tail or low end commuter machine the Mixer feels immediately nippy and with tight, track like geometry. It's nimble and won't complain when you throw it in to corners or weave through the traffic. The straight forks and short bars provide precision and you won't get thrown off when you hammer it over an unseen pothole so common now on London's winter ravaged streets.

The Alfine drive train delivers power with an immediacy associated with a single speed and there's no side to side movement in the frame or fork. The drive train is silent; no ratcheting whilst freewheeling and the Alfine shifts without a sound even when under load.

Alfine’s eight speed provides a good range; gears one to four are tight, five through to eight more drawn out. If you have the legs for it you'll pull away on the flat in five and spend most of your time in six and seven. The option of a 16 toothed sprocket is available if the low end is too grannyish.

On the flat the bike moves and will happily cruise along with road bikes half its weight. It's only when pulling away from the lights will notice you aren't riding something more aggressive.

In traffic the Shimano discs come into their own stopping the bike without drama and feel utterly dependable in all weathers. Some may question if they are needed and your mileage may vary; I enjoy disc’s consistency and ease of maintenance and the stronger wheels they demand cannot be a bad thing when smooth tarmac is in short supply.

At first glance the Continental tires look weak but don't be fooled; they are SportContacts and guaranteed puncture resistant. In reality this appears to mean you may get a puncture once every 300 miles if you cycle in glass strewn London; both so far have occurred in the rain.

Looking after it
The componentry is designed with low maintenance in mind and for the most part this is what you get.

Alfine requires no day to day maintenance although a service is recommended after 2000 miles. As per a single speed you will need to remove grit and re-grease the chain. If you’ve replaced disc pads before doing so will be straightforward although after 600 miles there’s no noticeable fade.

In terms of tweaks since purchase the positioning of the disc blocks has been adjusted as they've either shifted since being built or were incorrectly positioned during the build - don't expect to have to do this but if you do it’s a five minute job.

Conclusion
The Mixer has a lot going for it as a city commuter; it's smooth, comfortable at speed and soaks up whatever the city throws at it for the most part.

You could be justified in considering the Mixer over-priced and if you don't want the ride and longevity of a steel frame then this probably isn't the bike for you; similarly specified Alu framed machines can be had from Ridgeback and Scott for a couple of hundred quid less. But none of these options however will turn heads quite like the Mixer or provide the same comfort and class.
