My bike has come supplied with Schwalbe Sammy Slicks which don't appear to have a lot of tread for a cross tyre. They should be OK next week which is a flat, fast course but am I likely to need something else when it gets a bit muddier?

    Probably, yes. Something like the Schwalbe CX Pro or Challenge Grifo would be a good all-round tyre. I've never tried the sammy slicks, so I've no idea how they perform - they might even be ok.

    Unless you have many wheels or two bikes a fairly open "mud" tyre serves well in most conditions. Sure, it isn't as fast as a file tread on hard pack but you will have grip in the slop and wet rather than sliding on your arse. Something like the Vittoria Cross XL Pro or Conti Mountain King CX are good all round tyres.
  • I've got them Pross, but wouldn't fancy cornering in the wet or muddy. I have a set of Schwalbe CX Pro but yet to use them. Where are you racing?

    Llantarnam. First round of the Welsh series. It's a very flat and not overly technical course so should be OK. I'm probably only going to do 4 or 5 races this season so will try to get by on the current tyres, if I'm struggling I'll chuck some mud tyres on a spare set of wheels. Cheers all.

    Are 38mm tyres pretty much standard width these days? The ones on my bike look huge, I thought about 32mm was normal and I'm sure I used to use 28mm but that was on a converted road bike so I didn't have huge clearances. 38mm seem too big.

    32 and 34 are the most common sizes. In fact I think they might be the only two UCI legal sizes, no that this applies at Sunday League level.

    I use 32mm Conti cyclox kings - no issues with the width and the pattern seems to suit most terrain and conditions..

    That makes sense, 38mm look huge and you certainly notice them when riding on road! Comfortable ride on the bumpy bits though.

    For mud you want some nice deep, firm shoulder lugs for bite, particularly for off-camber traverses as being able to take the inside line on corners is where you can make up places.
    Make mine an Italian, with Campagnolo on the side..
  • Not to hijack this thread but can anyone explain 'open tubulars' to me? Have clincher wheels but reviews say clincher tyres are getting better and some of the best are of this variety. Was looking at the Challenge Limus but not sure how these things work. Sorry if I'm being thick.

    It's another word for a clincher, although the thread count (TPI) may be higher. Limus is a good tyre either way..
  • Technically an open tubular is a clincher... basically it has been built like the tubular it resembles, but instead of being sewn up, they add the beads at the sides and leave it open with no tube inside... Allegedly it will give you a similar ride quality to a tubular, which is kind of true... it is normally more flexible than a normal clincher tyre, so it will corner well, handle well etc...

    So do you still put a tube inside them?
