revising Roubaix tire selection?
So far, folks are recommending 25c tubulars as the premier choice, with 25c clinchers being the poorman's option. They've recently graded some sections of the course which softened it up alot in spots. Given this, what are folks thoughts on running file/minimal tread cross tires on a cross bike to better float over the softer ground?
It is a poor idea. Every
It is a poor idea. Every year guys try it at Kopp and Roubaix and it does not help. If you were to do it, you would want to run full road gearing for the paved parts, especially the tailwind downhills. All the fastest guys just run road bikes.
Apologies for not being
Apologies for not being clear. I was planning to run road gearing so there won't be a difference there. I'm debating between running 25c clinchers at ~95psi vs 32c cross tires at their max pressure, ~65psi. I've done alot of practice laps out there this year, and fine the road bike definitely faster, I'm just questioning the recent grading and the moisture from today causing the course to be softer than my 5-6 practice sessions of the previous month or two.
No worries. I would not
No worries. I would not want you to be out there spun out in a 48/12 killing yourself on the paved downhill’s!
Run the road bike with the 25. I assume the only reason you would run the cross bike is so you can do the wider tires? 65 PSI is going to be a hindrance over 3 hours (or however long your race is) and that is pretty low for how hard pack the dirt roads are and all the pavement. Remember it maybe wet today, but it is supposed to be sunny and warm for the next 3 days.
Don't over think it, that is my advice.
Thanks DBC!!!! You guys
Thanks DBC!!!! You guys rock!
Boulder Roubaix Bike Setup
Would love to see the experts cough up a little inside info on preferred tires/wheels/brakes/gears/etc. for upcoming Boulder Roubaix. Thanks!
Roubaix Bike Setup
I've found that wider (25mm) tubulars are the single best piece of equipment for dirt road racing. When I won B-Roubaix in 2008, I was using 25mm Vittoria Paves. Flat resistance and a smoother ride/lower rolling resistance are the key attributes here.

Bike setup
Jon Baker is right on, wider tubulars running slightly lower pressures(around 90 psi) would be the best setup by far. Wheels are the single most important part of the equation so if you don't own tubulars running tubeless tires on your existing clincher wheelset would be a solid second best. 25mm tubeless tires at 90 psi would provide a fast and supple ride, dramatically reducing vibration and lowering rolling resistance and increasing flat resistance over clinchers with tubes.
The only 25mm tubeless tire,
The only 25mm tubeless tire, the Hutchinson Intensive, is actually smaller than the 23mm Specialized S-Works Turbo Tubeless. Even though it's smaller, it's heavier. The Intensive tires are great for training (cost less, last longer) but for race day go w/ the S-Works Turbos.
If you can pull off the long
If you can pull off the long course then bravo! It looks awesome. Even I'm not ready in April I'll do it just to support the race.
Sweet!!
Great to see this event back on the schedule. By far my favorite ACA event. So much better than an office park crit. Thanks DBC!!!
A lot more volunteers and
A lot more volunteers and Sheriffs will be needed. 4 Corner race to a 11 corner race. 5 corners will be crossing traffic.
Downhill section on 53rd between St. Vrain and Hygenie Roads will be wild.
What about the Boulder Gran Fondo that is scheduled to run out and back on St. Vrain?

One of the events will not get a permit for the day.
YES!!!
The new longer course looks amazing and like it will create a truly wonderful challenge to the racers. These are all regular training roads for me and I can't wait to attack it!!! Bring it on Boulder Roubaix!
sweet. glad this race is
sweet. glad this race is back.

The long course looks awesome. Sign me up if you can pull it off!!
