I have seen a lot about tubeless road tyres recently, I think Steve Abrham is using them on his record breaking attempt, has anybody experienced them yet. I have successfully run tubeless on MTB for a number of years and I am considering giving them a go on the road using existing rims (H plus son archetype) or if the advantage is great I could be tempted to build some new wheels with Stans rims, but the higher pressures & speeds involved with road cycling are questioning the decision.
