Just to add to the mix there is also the tubeless tubular options from Donnelly and Tufo ( Tufo makes both). I've gone to the dark side and bought a tub wheelset. It came with challenge baby limus glued on so I'm going to give them a try over the summer before fitting the tufo tyres got from Ribble for just over £60 a pair. If they turn out to be a bit pap I'll stick with the challenge tyres
The Donnelly tubs are a lot more pricey, the cheapest I've found is £86 a tyre and are almost and exact copy of the baby limus,but if they are easily repaired it may turn out to be a cheaper option in the long run. Has anyone on here tried them?
