I am going to convert my fixed to a single speed cross bike. it is a On One Pompino with a wide carbon fork. i'm currently running 48 x 18. 70". I think that 60" may be best.
The wheels are Mavic CXP33 rims.
Any advice would be great.

    that all sounds fine, just get some good rubber and away you go.
  • any tyre recommendations?

    Tyre choice depends on conditions. I've been using some Specialized Houffalize tyres which are cheap & OK for the sandy conditions in these parts. Schwalbe Landcruisers are heavier and tougher - depends on how much you want to spend too.
    Make mine an Italian, with Campagnolo on the side..
  • I have done exactly the same thing -

    I transformed my pomp to a CX steed (although it's got the steel fork) - I fitted a 42 (i think) in place of a 48 and it goes fine (18t freewheel). I have come "not-last" on it, so it can't be that bad, and I really enjoy using it for messing about on bridleways.

    i've got conti speed-kings for tyres, which seem to be ok. (although I only got them because they were on offer..)

    If you want to really compete with the (boring) people on the (boring) geared bikes, I'd suggest practicing dismounts/short hill sprints/mounts - on the steep stuff, you will have to run. otherwise, enjoy it, it's an absolute blast. really, really good fun.

    One Gear, No Idea. :)

    i built mine up as a Cx but left it fixed and I can ride most mtb trails on in including the north face at grizdale.
    I've got racing ralphs on it and they have been good for the summer

    it looks like this

    any tyre recommendations?

    Schwalbe CX Pro Lights are good, Michelin Mud 2s also though not quite as grippy as the former in my experience. Both are, I think, 700c x 30mm.
    I've also used Hutchinsons in the past, another good brand and their new 700c x 34mm Bulldog model looks worth a punt. Bit out of my price bracket for this autumn though.
