I'm riding with a 28-622 (700 x 28C ) tyres I find the ride a bit complicated , the tyres are for someone experienced and in the slim side I'm an average rider not heavy but not slim enough I will feel lot more comfortable with a more regular tyres , those are thin for a fast sort of race ride , requires lot more equilibrium, stability , I just want a more average ride with a bit of speed time to time while we are confined though I'm starting to enjoy the ride but I would prefer a more stable tyres .
