• There's at least 15 watts in Crr losses from those tubs compared to a proper race tubular. How much do you think your 55mm carbon wheels are saving you?

  • I clearly didn't put much thought buying these as they were too cheap .. just got them for strava segments and the baller deep section carbon look ..

    Recommend me a half decent tub that wont break the bank if this removable valve core thing is a deal breaker I might as well need to get them.

  • Any of the usual suspects, Vittoria Corsa, Schwalbe One. You have a £?k bike with Di2, don't scrimp on the only thing that's connecting you and your power to the road.
