Going from a cheap tire to Bontrager R4's was noticeable.

Yeah, but the Michelins aren't "cheap" tires. It'll be interesting to see how the new tires work out.

that's ridiculous. are h3's even allowed in mass start races now? i wouldn't want to get a hand stuck in one during a pile-up.

for anything other than cat 5, i think those kinds of rules are a little dumb. it's a race. you have the right gear for the game.

It's the NASCAR effect. Lower costs and level the field. At least it's an LA thing.

Why? I race on the Pro4 endurance. I'll take the .0003% rolling resistance difference in order to not flat out in a race.

I'm thinking the same way, but I was wanting to try them out just out of curiosity anyway. I've got the fresh set of P4Es on the bike now, and three more P4Es in the box when they wear out.

Mmmmmm Mr. Shovel we may need to do some business at Mayor's cup this year.

that's the notion- in hopes that more people will think they have a fair shot and pay the reg. (they don't, and numbers aren't up, but w/e)

you an me both- but road racing is dying off around here at a rapid clip, people are trying all sorts of dumb stuff to slow the exodus to CX/MTB/Tri/Mud-Color runs/Track.

Probably a super remedial question, but here goes. My bikes all have BB86 shimano bottom brackets. Can I use a Rotor 3D crank set without having to change the bottom bracket or adding any adapters? Rotor's lil pdf guide would lead me to think I could. Contemplating grabbing a closeout power2max power meter.

there are no remedial BB questions.

I think yes, though, per this chart?

Hey, long time. From perusing results it looks like you are having a good season and you are progressing well. I'm done for the year for racing. I wasn't planning on attending the Mayors Cup as I am working the CT Cycling Festival the next day, but plans change. Hit me up offline.

Si.

I think you are going to have to buy another bottom bracket. The chart fudgy posted shows bb type comparability. But you probably will need a Rotor-specific bb.

Bummer :( Am I wrong to think unecessary changing of press fit BB's could lead to premature wear of the shell?

basically. if you do it correctly it shouldn't wear anything.

Yeah, it shouldn't be a problem if removed properly. Most press fit BBs - which is what is in a BB86 - have a plastic or rubber shell around the bearings, so there isn't much to cause damage.

This should be the BB you need: Press Fit 24 BB (BB86) - BB8624. And I think the reference to Shimano standards refers to the frames being made to fit Shimano cranks. I don't think it refers to the ability to use Shimano cranks in Rotor BB and vice versa.

I miss loose balls and square taper.

that's why I sleep naked, but what's a square taper?

Yep, and I train and race on Conti GP4000S IIs, for similar reasons (having only one wheelset is another reason). There are faster tires, but both the Pro4 Endurance and GP4000S (II) are at a very nice sweet spot of rolling resistance, durability and flat resistance. If maximum possible performance is the goal, different tires are a good thing to target, but there are other factors to consider.

Sign me up for an 11-21 or 11-23 DA cassette. Inbox me

Guys - Have you found any rolling resistance comparisons that include the Pro4 Endurance? I'm thinking like you are, just wondering if there's anything out there other than seat-of-the-pants impressions.

i know i've got both.

I have every combination of 11t and several multiples. I need to go through them all first to assess condition. That will give Teton first shot at selling his.
[/quote=shovelhd]

thanks. it will likely be early next week before i assess everything. i know i have 11-21, 11-23, 11-25, 11-28...probably 12-25. ulty and DA variants.

i just need to dig through a box and see what is new vs used. don't want to sell any schwag.

I would also take DA 11-23 and DA 11-25.



Rode the H3 today. It was a dream. I need to sell the Williams ASAP.

I used to ride on Specialized Turbos, but honestly prefer Pro4s. They last a bit longer, less issues with quality, and I think they have better grip in the wet.

My tastes are more plebian. I'd like an Ultegra 11-23, please.

The current production S-Works Turbos are supposed to be a significant improvement over earlier models. I guess I'll find out.
