Dear Lennard, Question for you re: forks for long head tubes. I'm 6'4" and have a Seven Axiom with a roughly 30cm head tube and a Seven rebadged Reynolds carbon fork on it. It is a bit flexy when braking while cornering and I'd like to improve that. What options are out there and how do they rate vs. each other? I know Alpha Q makes one with a steerer long enough (as seen on your bike) as does Storck, but want to understand if they are better than the Reynolds vis a vis flex/rigidity. Ted Dear Ted,

A recurring pain
Dear Lennard,
I'm writing because I just read the shoe review in the VeloNews Buyer's Guide, and you mention in there that you use a custom orthotic. I was happy to see that the Shimano SH R300's I just purchased got high marks, but I am still having issues with my right foot even with the new shoes. I got the new shoes because I was having the problem with my four-year-old Northwave Evolutions.

Dear readers;I get a lot of questions about cranks – crank lengths, non-standardcranks, compatibility, etc., so I thought I’d just combine a number ofthem here.  --LennardDear Lennard;I would like to read your comments or opinions on a product calledPowerCranks (see at Powercranks.com). I would like to buy a pair to improvemy technique. Thanks for your help. --HeltonDear Helton;PowerCranks are cranks with a clutch bearing at the bottom-bracketconnection in order to only engage the bottom bracket in the forward direction.You can only keep them turning if you pull up and around the entire

In addition to the teams mentioned yesterday, Kelme is also using wheels with carbon braking surfaces – namely Shimanos with carbon rims. Like Shimano’s aluminum wheels, they have paired spokes with their heads in the side of the rim and nipples at the star-shaped hub. Kelme uses Shimano’s red cork brake pads with them. ADA also makes a rubberized cork pad for carbon rims that are claimed to provide consistent braking on carbon rims, even when wet. Its pad fits in both Shimano and Campagnolo brake-pad holders, but not in Corima pad holders. Telekom has been using ADA pads in the past but
