Hello!
I would like to ask you guys, anyone of you riding a fairly light wheelset (I am using Mavic CCU) who has tried the wider rim wheelsets?
I am certainly curious on for example Easton Aero 55 tubular or Ax Lightness Stream 55.
I use 22-23mm tires in front and 22-24mm rear. Only tubular of interest at this point.

Please share

Regards

I would think asking on the racing forum would get you the best answers.

Keep in mind that for clinchers a wide rim broadens the tire base, allowing the tire to hold more air volume while keep the sidewalls more vertical. This has the effect of softening the ride, reducing pinch flats, etc. Wide rims for clinchers is primarily to improve tire performance and a little bit for aerodynamics.

With tubulars that is NOT the case. Tubular tire air pressure merely fills out the casing. It doesn't matter what rim you put that tire on because the casing will be the same shape for a given pressure. Wide rims for tubulars are primarily for aerodynamics. There is no difference as far as tire performance goes.

The only time rim width makes a difference is when the tire seat area has a different curvature. If you have very wide tubulars and you have a flatter/wider tire seat area then a wider tubular rim might be better for tire secureness. This is more a factor for cyclocross or dirt/gravel road type situations.

I've been running wider Stingers 6s since 2010 (28mm max width, about 25mm at the brake track). I've run 21, 22, and 23 mm tires on them. I also have a 2011 or 2012 Stinger 7/9 set (front/rear) and a 2010 Stinger 4 front. I've only run 23 mm tires on the 7/9, haven't ridden the 4 yet.
