Why does my tubular tire thump near the valve stem? I have ridden them several times and I have noticed a significant pulsation whenever I coast at 20-28 mph. I don't notice it when I am pedaling although it is probably there.

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.

It’s a good question, but one I thought might be best answered by the folks at Zipp.

Dear Readers,
I have received so much mail about the " tubulars vs. clinchers rolling resistance debate that I could not resist running some of the better ones. The debate may never end, but your letter sure have raised a lot of issues that I’d never considered.
Lennard

Tubes, tubulars or NoTubes?
Dear Lennard,
I'm currently running Campy 10-speed and am interested in running Hutchinson Tubeless Tires. It appears that the only officially approved system is the Shimano Dura-Ace wheelset, which is obviously not an option for me. My question is will a wheelset with rims that do not have pierced spoke holes on the interior (like the Mavic Ksyrium SL, Campy Shamal Ultra or Fulcrum Racing Zero) suffice and is there anything special that has to be done to make them work?

Lennard,

Dear readers,I’ve been wanting to write about rolling resistance for years, and I’ve had ongoing e-mail conversations with a number of you on the subject. Indeed, I’ve built up enough of it to compile a collection of some of the most interesting.Lennard WaterDear Lennard,As I was riding though an unexpected rainstorm, I noticed that, even with the rain, it seemed to take less effort to ride on the wet road than when it is dry (all other things – especially wind and temperature – being constant). I know that there is less friction when it comes time to stop or to turn. Could it be possible

More tire talkDear Lennard,I really enjoyed your recent wet-road tire discussion with Tom Petrie and Alberto De Gioannini. Just the topic I was looking for, but I'm still a little confused. I thought the cord compound made a big difference and it wasn't mentioned at all. I recall racing in the rain in a crit next to a friend who was running cotton-cord sew up tires as opposed to my silks. While we'd been comparable in bike handling otherwise, I found myself nearly sideways in corners while hewent around like on a rail. We'd pumped our tires to comparable pressures.I'm taking a group over for
