Although you and I may never earn the right to tattoo the Olympic rings on ourselves, that doesn’t mean we can’t ride an Olympic-quality bike. Pitiful consolation, I know, but it’s something. Matt Reed is known as an all-rounder who is ...

Dear Lennard, You mention you use the No Tubes set up with your Ksyriums and Hutchinson’s Road Tubeless tires. I would like to do the same, but am concerned about Hutchinson’s warning against doing so. Something about ammonia breaking ...

Dear Lennard, Why would changing a tire on a Zipp 530 be so difficult? I beat my fingers and snap tire levers trying to get a tire off. -Steve Answer from Zipp Lennard, Because the intended use of Zipp wheels is ...
