Bicycle construction and use.
Exact tube angles, mm-precise bike fitting sessions, questions and concerns over whether you can safely run a 23mm tyre at one end and a 25mm at the other...
Yesterday, I replaced my 20" front wheel with a full sizer.
That's a 559x28mm, by the way. It will easily fit 700C but my legs are just slightly too stumpy with 175mm cranks (can you guess what the next purchase may be?), leading to a little bit of hard overlap, below:
Let me tell you, it's strange. Superficially I'm not any higher up (same back wheel) and the front end can only have risen by 3" or so, but suddenly it feels like the chainring is sawing threateningly at pedestros, I have to peer around my legs (and through the boom/mech) for potholes and I have an odd fear of falling over!
Luckily I can still handstand. With dual 700's I don't think this will be possible, making it less practical for the commute (unless I go back to MTB shoes, I suppose).
I was inspired by the thought of having something with two big wheels but retaining the "downness" of a lowracer - like the M5CHR. The question everybody wants to know (including me) is whether it goes any faster.
Good question. When I'm brave enough to give it some welly, I'll have an answer!!
(yes, I took the pics before I fitted the fork. Thanks
