It's not the brakes imposing that constraint, it's your frame. So one option is a new frame.

If I were you I would go to 24mm tires like GP4000s.

yeah, but i was wondering if different brakes might give me a little more room with the same frame, since that would be a much cheaper solution.

and they are GP4000s. do those run large?

Give Duracci or Sram Red brakes a try. Most brakes should clear 25mm, it's 28mm that gets you in trouble

Actually, i donno about Duracci, but i think they should accommodate large tires. I definitely know that my Sram Rival brakes didn't play well with my tubulars on HED Stingers, though i can't remember if it was a vertical or horizontal clearance issue. Either way, i had to sell those and get Sram Red.

I think the DA brakes didn't open enough. I know guys that filed their brake arms (SRAM and DA) to clear wide tire/rims.

are there any brakes that have more clearance? again, the issue is vertical tire clearance, not horizontal rim width clearance (although i guess they seem to be related).

edit: and yes, i realize one solution is just to use 23mm tires.
I see you have a Jamis, I have one too. I'm having the same problem with 25s on my wheels. Wide enough to fit the rim but now rubbing the top of the tire. Maybe it's a fork thing with Jamis, just need a slight longer fork which would then allow the pads to be postioned further down on the brake.

found a solution with the help of the mechanic at my LBS. basically, you need to fiddle with both the adjustment screw on the brake arm and the bolt holding the brakes on the fork. by messing with those two and with the cable tension, i was able to find a position with enough clearance. i had to crank the brake adjustment screw as far as it would go in one direction (can't remember which one) and then twist the brakes in the fork. hope you can get it to work as well.

in case anyone else is interested, it's a jamis xenith comp with DA 7800 brakes, HED jet 5 (23mm C2 rim), and 25mm conti GP4000S tires.

Yeah, I've fiddled with those 2 adjustment screws. Somehow they adjust the spring tension or something - I'm such a master mechanic! I may try an extra washer to push the brake farther out from the fork which may help too - puts it farther out on the wheel.

not the spring tension bolt...the little screw on top that controls horizontal positioning. if you already did that, then i dunno...that's all i've got.

Question for the 33:

When sprinting (standing and leaning forward), my rear wheel "lifts" and loses contact with the road, long enough to lose traction/speed.
Is there a trick/technique to prevent this? (It has happened in the past, but today was much more pronounced, at the worst possible time).

Thanks.

This question has been answered at least a hundred times. The problem is your center of gravity is too far forward and you are not compensating enough pushing with your bars, hence your rear wheel hops. You need to find the right balance on your bike during hard efforts out of the saddle. I find it best to do this by starting with form sprints and working up from there. Put some form sprint work into your schedule 2x/wk. Keep the power down to a reasonable level. Concentrate on body position, keeping yourself stable over the bike, and shifting through the gears. You want to be pedaling in circles with the bike flowing beneath you.

Yep.

Another contributing factor could be that your stroke is inefficiently continuing to push when your pedal is at the bottom of the stroke. Since the pedal can't go down any more, your hips go up, and the inertia of this little jump carries your bike with it. Form sprints will fix this as well.

depends. FSA has quite a few different standards, and some are shimano (24mm on both sides) compatible.

though seriously, you just got yourself a Duracci SRM. get a bb that's worthy of a high-end PM. A new BB7900 is about $30, i think

This feels like an appropriate place for this question. I need a new stem, is there much of a difference between stems besides weight? What should I be looking for?

You should be looking for something that is the right length and attaches the bars to the steerer. That's about it.

Yeah, I know the length and angle that I want. I guess just wondering if some new, wonderful stem technology has been developed that I'm not aware of.

^^ Other than the ones with the secret hidden battery to power the secret hidden motor, not any functional difference.

Anybody wearing the Specialized Evade helmet? My team switched to a Specialized shop this year and we're supposed to get a pretty good deal on helmets. There's been a healthy debate on the team message board on the Evade v. Prevail.

Personally, I think the Evade looks ugly and hot. Anyone have personal experience with it?

I think the back looks silly on them. Of course, I just got an air attack and now I look like a power ranger.

I recently bought a new helmet, and I pretty much always get whatever feels nice that costs ~$50. The guy working the floor at this particular LBS was very nice and helpful. I didn't need much help, but he didn't know that. As I tried on a $45 helmet, he told me that all of the helmets pass the same safety tests, then asked what I was using it for. "Racing."

"Why are you buying such a cheap helmet?"

"Why shouldn't I?"

"How much do you spend on shoes?"

"Umm, $300?" (well, that's retail value anyway)

"Why would you spend 6x as much covering your feet as you do protecting your head?"

"Didn't you just tell me that all the helmets pass the same tests?"

<crickets>

"On a 3 hour ride, my feet have been uncomfortable in $50 shoes. My head has not been uncomfortable in a $50 helmet. I'll take this one."

Nice try though.
