Pirelli

Wanted to pair up these tubes with the RS tires for summer riding KOM hunting. It tells you not to use with rim brakes, but one month in with some hard braking no issues. Wish there were more options for valve stem sizes as the 85 seems too long for my 50mm wheels. I usually use the pink tpu tubes sold on amazon for half the price and they have a 65mm valve option which is ideal, any savings in weight on the pirelli tubes is probably lost by extra valve length and not as aero.

Im all in on tpu and after 2 seasons on pirelli p-zero smartubes ended with a failure at the valve flange and unexplained leaks from rim side of the tube, and a few months on tubolito-S ended with a glass puncture and then tiny holes I was unable to patch on a new tubolito-S I have moved onto these. I was going to get the new Silca tpu tubes but after seeing these as the fastest tpu tubes on bicyclerollingresistance.com I went with these instead. Easy install. Feels smooth and fast. No problems yet. Valve resists connecting to my floor pump a little but not bad.

I ride 150+ miles per week on paved roads and trails. Occasionally, crush limestone. Took the plunge after reading all the reviews and am not disappointed. Easier to mount than expected on my Fulcrum Speed 40c carbon fiber wheels. I did not inflate to the full recommended pressure based on Pirelli recommendations as 100+ psi seemed nuts. Ride and handle great. Grippy. Replaced Victoria Corsa 28mm. I like the Victoria but seems like they are pushing to go full tubeless and these rims do not support that.

I've been using TPU tubes for about three years and the Pirelli have been the most reliable. They are light, ride nicely and pack easily. They are easier to maneuver during mounting and I've have no issue pinching a tube on installation. I have had a couple issues with early failures and it seems to be in the stem/valve area (other brands were worse). But any flats on the road also wrecked the tire, to it was not a tube thing. While I use tubeless for MTB, it's been a pain with gravel and since most my mile are road I don't want to mess with the goop. TPU is my choice for gravel and road.
