Just to answer Eddie's point. Hubby's bike is a hybrid mtb with 2" tyres. It fits into the stand with about 1/2" to spare and he has fitted the stand on our garage wall about a foot up from the ground so the bikes are stable in there - just park and leave basically. You'd need to ask any ebayer you were thinking of buying off about the gap size to be sure.Stands such as the one that Lanclass has linked to, which are fine, can be pretty unstable when used in conjunction with a mountain bike. On the versions that I have seen tried, the tyre profile and sizing doesn't work that well. Either the tyres won't fit in properly, or aren't held rigid enough as the stands are neither deep enough, or tall enough.
