29 rims on 26 frame... almost on KTM

[JTK]

Ok, so I have too many bikes Can one ever have?

 

I have a KTM Ultra frame that I was going to build up into nice litte ride with a XT groupo but have decided one something else. I am thinking of turning her into a SS for town use. Last night I took my 29 back wheel and shuved it in the Ultra rear drop outs. The wheel does not turn but can go in with a little force wearing a new crossmark. This made me think. What if I put a slightly lower profile tyre on there, something somewhere between a slick and full mountain bike tyre. Something like the old black bike tyres, as this is really only for riding around town, it should work right? Anyone ever done that? To me the frame looks closer to a road frame anyways, al be it nicely fluid formed... What fork should I use then? A rigid carbon comes to mind in 26?

 

I think the bottom line here is though. This frame would be a perfect candidate for 27.5inch wheels. Almost seems like it is made for it. Or rather seems like the geo is made for 700c

A set of cyclocross tyres and you are sorted. Some funky bars and you have yourself a sexy commuter.

 

Convert to SS

Thanks Maxxis. was the kind of info I was after...

Planning on doing the same thing, get some cyclocross tyres, 29er wheels, and some old rode parts and build my old 26er up as a cyclocross bike for those loooonnnnngggg base miles.

Anyone have a good cyclocross tyre suggestion? and how does the 700c sizing work? Sorry, never been a roadie. is 700cx30 a bigger volume tyre than a 700cx20 for instance? what is the x20 mean? 20mm? is that the height once pumped?

The x30 is supposed to mean the width in mm (or inches in the case of 29x2.15).

Thanks Eldron. That makes sense. So one woul ultimately look for around x30 maybe max at 35?

Get yourself a set of nice high volume cyclocross tyres.... Im busy with the same setup and got a set of 29er rims at a steal and added some 32c Conti cyclocross tyres.... Using an old RM3 26er frame and there is MORE than enough clearance... The wheel actually almost look too small in the frame

[JTK]

I was thinking of these http://www.chainreactioncycles.com/Models.aspx?ModelID=24614 think they will cover most bases maybe just wear out soon.

Those look nice. Ill check with my partner what he uses on his CX bikes.

 

Just in a meeting quick.

[BogusOne]

Bought them last year sometime at Cape Town Cycles. But i believe they are not around anymore and that Mark has set up shop somewhere else...

[JTK]
