Bicycle Maintenance

Bicycles are great. I ride mine almost every day. To the office, around town, in the countryside, to the allotment, with friends or on my own. The sad truth however, is that an awful lot of people who could ride bikes, don’t. In the UK only 2% of journeys are made by bicycle, compared with 9% in Sweden, Finland and Germany and 25% in the Netherlands (Bassett et al. Journal of Physical Activity and Health, 2008). Along with our lacklustre use of renewable energy, our cycling rates are also languishing at the bottom of the European table. I’d like, and expect, to see more people riding as energy prices rise, the economy continues to struggle and environmental pressures (both local and global) increase. A five-fold increase sounds incredible, but would only equal what many other European countries are already doing, and still represent only half the amount of cycling the best countries manage. It is achievable.

In April last year I spent two weeks in Lincolnshire with Alf and Teresa Webb at The Bike Inn completing my City & Guild’s qualifications in Cycle Mechanics.

Since completing the training I’ve been working with Ross Taylor of Taylored Cycles offering the award winning Bristol University Cycle Surgery to staff and students and volunteering with The Bristol Bike Project.

The Bristol Bike Project also won an award. We won the Grassroots category of the 2011 Observer Ethical Awards and here’s the video:

Tools are important and I now have a fairly comprehensive toolbox. I’ve also recently built a bicycle wheel truing stand, more details here: bicycle wheel truing stand for building and repairing wheels. The only tools I’m still lacking are for the headset (press, remover, star nut fitter…), frame preparing tools (bottom bracket taps, crown race cutter) and the all important workstand!

This year I’m venturing into the world of frame building, with a one week course, again in Lincolnshire with Dave Yates and another with the soon to be opened Bicycle Academy. I say soon to be opened as they are currently setting up their workshop following a fantastically successfully crowd funding. They succeeded in raising over £40,000 in under a week though the new peoplefund.it project.

Watch this space for my adventures in frame building!

Bicycle Wheel Truing Stand

A bicycle wheel truing stand is a must have tool for any bike mechanic. The shape of the wheel, its lateral (wobbling side to side) and radial (up and down) trueness are a function of spoke tensions. By using a spoke key and tightening either odd spokes or adjacent pairs of spokes, out of true wheels can be gradually straightened out.

There’s nothing fancy about a truing stand, it simply has to hold the wheel firmly in place as you spin it, and have indicators of the two degrees of trueness. Commercial stands are at least £50 and you can pay a lot more. There’s no need though. I learnt to build wheels with Alf & Teresa Webb at The Bike Inn on an old cast-iron stand with perfect results.

Here’s the stand I built, loosely based on Roger Musson’s design from his book, The Professional Guide to Wheel Building:

The completed stand with a 700c wheel.

The upright in the foreground can slide in and out to accommodate a range of hub widths from 100 mm front hubs, up to 150 mm dowmhill rear hubs. The two gauges are free to move around on the white surface making adjustment very fast, no fiddly screws to wind in and out, no levers, and swapping from a 700c wheel to 26″ is instantaneous. The gauges are black plastic which show up great against the white background. The corner gauge is used for lateral trueness with the longer angled one for radial trueness.

Obviously for radial trueness (is the hub in the centre) the tyre must be removed.

In total it cost about £15, I bought the M8 nuts and bolts, the angle brackets and a lump of aluminium for the ‘jaws’. The wood and plastic was all scavenged from the street/skips.

I am still lacking a dishing gauge though, haven’t quite worked out how to make one I’d be happy with yet. Any bright ideas, let me know!
