24" wheels in place of 26" ?

[jimihendrix]

Any problems in fitting 24" wheels in a frame designed to take 26 ?, i cant think of any but wondering if there is something i've missed :?

The idea of fitting the smaller wheels is to reduce the standover height.

Bike in question is this Club Roost DH8 (i recently bought as a bare frame)

I've seen 24" wheeled Specialised Big Hits with special shorter rear ends, wondering if i can get away with the standard rear on the DH8 ?.

Bike will have disc brakes, forks will be upsidedown Marzocchi Shivers (like the ones in the pic) so a 24" tyre in the forks shouldnt be a problem, tried a 26x2.35 tyre in the rear moved back two inches, it catches the V brake bosses which will be removed, it's a bit tight in at the chainstays (where they pinch in) but i'll get away with it, with 26" wheels the BB height was something like 14" so that can cope with coming down 2" no problem.

Anything i've not thought about ?

BB height would be the only problem but not in this case. Could try to read a bit more into why they stopped doing 24" big hits.

Actually, the BB would only drop one inch by going to a 24 inch wheel.

Jimi if you are at the pentlands meet on friday evening you can try miniKens 24 inch wheel if you bring the frame, no tyre though.

I've done it in the past, there was a bit of a fad in DH for it a few years ago. Mostly you switch from 26" standard tyres to 24" monster tyres which means you don't lose much in the way of BB height but in theory gain grip and traction from being able to run fat tyres at low pressure.
I didn't like it much, wheels felt too heavy and the bike wasn't as stable at speed nor was it more manoueverable either.
I've still got the tyres and tubes - if you want to buy them send me a pm.

Cheers for the offer TK, but i wont make it to the Pentlands meet, driving the truck on a Friday means i'm lucky if i'm in the house before seven :roll:, pretty sure i will make the 24's work though.

Cheers for the offer of the tyres Stevet1 , what size are they ?, i recon the absolute limit on the DH8 will be a 2.5 on the rear.

I'll check. Are they 24" wheels in the top pic? Look like it but it may be an illusion.
