your own time trial disc wheel...
I made one of these years ago when I was a poor
Ecology student, in fact I used to make lots of go
faster bits because I could barely afford new tyres
let alone anything flash!
idea comes from spending most of my childhood
building RC models, or rather rebuilding them after
Iíd smashed them up.
still rather begrudge spending £1000ís on kit, Iím
not sure itís really worth it. Okay, if I was
missing out on National podiums by a few seconds Iíd
think about it but at my level Ė nah. Iíve got a
nice set of retro Spinergy wheels but the rear one
flexes like mad and creaks and makes cracking noises
and I donít really trust it.
Anyway, the starting point is an old 700c wheel with
two broken spokes that I found in the shed. Six
quid later, itís fixed and running true.
cut out a couple of bits of thin ply to fit around
you need to build a cut out that will allow you to
reach the valve of the inner tube.
Right, the fun bit! Take a bit of Solartex big
enough to cover the wheel. Cut a hole in the middle
and stick the Solartex to it.
Then, cut the sheet just big enough to fold over the
lip of the rim and stick it in place inside with a
Finally, with a hot air gun (carefully) shrink the
Solartex until it is
drum tight. Then do the same to the other side of
Tada! Super slippery disc wheel that looks like a
carbon one (at a distance) but without the huge
weight penalty. Only drawback is that you canít now
use the rear brakes but, hey.
Solartex can be found at any model shop
