My R2 has staggered wheels... HED Jet 4+ front (46mm) and HED Jet 6+ rear (60mm). My bars on that are also 38mm. As far a cross winds... I do remember that from COR! The reach on the 19 S3 bars is 10mm longer than my current Zipp bars. They do make the Black &Red S3 in a Disc. They just do not offer it as a frame only as a disc.

Sounds SWEEET. When I put my (51) S3 next to a (54) S5 the handlebars on mine are about 1 3/4" (44.5 mm) Higher. At 64 I doubt I will ever be able to get comfortable that low. My S3 was my bike of choice on a VERY windy day to do my Double Century last May. I have been looking at a Red /vBlack S3... The Trouble is... They only offer ...

I just saw a S5 and a S3 in person. I kind of like the Rat system. Why do you not?

If you do the RED hydraulic... Reach out to me.

Welcome to the forum!!! Personally... I would go with the 50 / 34 an a 11-30... I have made the mistake of not having enough gear to get up a hill in the past. (Not sure your rear der. will handle a 11-30 though) The new S5's come with a 11-30.

I have seen pictures.... PRETTY cool!

I just received the answer... (mine is a 51) Yes they are the same.

I am looking at upgrading my P5-Three to a P5-Six. I have found a fork that is from a 58. Is there any difference in the fork to my 52?

What size is it?
