    Inbred as a "cross" bike?

    I picked up a cheap 8 speed STI 105 equipped road bike with an really rough, rusted frame.
    I'm thinking about using the components to build a poor man's cross bike. I'd use it for rail trails, double track type riding.

    I'm trying to decide between buying another Inbred 29er and putting a cross fork on it or buying one of the road/cross style frames from the OnOne site.

    I'm a little concerned about the cross frame only having a 130mm rear width making it harder to get wheels. Plus if I don't like the bike, it may be harder to re-purpose it or sell.

    If I use an Inbred frame, a cross type fork will steepen the head angle a small amount but not make it unrideable - I think. It's 390mm. I figure I can swap wheels around from my other 29ers until I pick up a new wheel. I'd throw a Midge handle bar from OnOne on it. And if I don't like it, I can just turn it into another 29er.

    Any thoughts on either solution?

    If you're looking to test the waters and tool around a cross course a bit, then a monstercross bike or a 29er will work just fine for that. If you're looking to be competetive, you'll want a dedicated cross bike. There are almost always 29ers in the C field at the cross races I go to.

    You do not want to use a 'cross fork on an Inbred frame. The 29er is designed for a 470mm A-C. Using a 390 A-C fork would steepen the head and seat tube angles by nearly 5 degrees and lower the BB. Would destroy the handling. Stay with the mtb fork.

    If you want a 'cross type steel bike, look at the Kaffenback. Canti or disc brake, 135mm rear spacing.

    Note that the frame should be on sale at $179 (fixing it). Fork is $40.

    The trouble with common sense is it is no longer common

    Thanks Shiggy - the Kaffenback is 135mm? Cool, I had one sitting in my cart but there isn't much info on the web site.

    Hot Damn, I've got a Kaffenback frame and fork, Midge handlebar and cross style headset on the way from the UK.
