Building a disc wheel

Postby wellbeloved747 » Sun Feb 17, 2013 00:03 am

I could do with a disc wheel this year as i am doing a few time trials i was looking for a zipp to go with my 808 front wheel however they are in excess of £1,200.

i have seen these plastic cover things but i don't like the idea of them and want something a but more solid and "weighty".

a quick search bought me to this video:

so after a bit of planning i have decided to give it a crack. My aim is to first try this with a cheap wheel maybe a £25 Mavic if i can get one. something of this quality

I would then place it in a cardboard box and flood it with expanding foam. once dried i would sand and level it and then glue a depron sheet on top.

here comes the questions:

once i have glued in the depron or foam with carbon matting and resin bond the the foam?. or will i need a card sheet?

what wheel should i use? no worried about quality as this will be tested on my alley before a proper is made.

Any tips? or words of advice?

There's nowt wrong with the Aerojacket covers. In fact they are more aero than quite a few proper dics in tests.

looking at the bikes you have got/had I would just buy a disc wheel and save the hassle.

I will only use it twice a year and for £1200 seems a bit much

I've used the wheel covers and they're good. An excellent option for you I would have thought ?

Better still don't bother with a disc at all, it wont make that much difference, if any. Yes I know that the pros use them but they are averaging about 30mph.

Exactly, you need to be able to ride at that pace. Fair enough if the OP can. Unless you are able to the advantage of a disc on the fast sections of a TT will be more than lost if you are not fit/fast enough to keep it going on the drags. I have come across folk running discs on hilly courses and the drone of the disc on the uphill sections is painful to hear. Yes they are fast but in the right conditions and you def' have to be fit enough to take advantage.

Bearing in mind the OP owns a Shiv I'm sure he'll be racing at that pace...

I also notice that he is 15 years of age and not been into road bikes all that long.
