Anyone know the size of the seatpost on the older 575s? I hat how often my race face slides around so I am thinking it is time to get a Thompson.
Thanks

Ditto- 27.2.

If your seatpost is slipping, look into getting a tighter quick release clamp rather than replacing the seatpost!

Thanks,
I read posts on replacing the clamp and a lot of people indicated that switching to a Thompson helped a lot too.
