saddle/seatpost clamp slippage(12 posts)

saddle/seatpost clamp slippageJS Haiku Shop
Oct 17, 2002 6:31 AM
Brooks B17 Narrow, Ritchey Comp Seatpost, under 1000 miles on the whole shebang. Saddle stays in same place fore/aft, but continues to slip nose-up. I completely loosen the seatpost clamp, readjust tilt (with a level), tighten down really well, and ride. Notice tilt again within 300-400 miles.

Your advise appreciated!

TIA!

It's a common problem with the Ritchey post. There's not much else you can do besides getting a different seatpost.

I have a Kalloy post, which is the same design (I've even heard Kalloy actually make the Ritchey posts?). It seems the ridges holding the tilt are too shallow or soft. Roughening all the contact areas with sandpaper helps a bit, but I decided to get a two-bolt clamp. I'm heavy in the saddle.

I've taken a triangle file to exaggerate the serrations for a customer. They didn't bring it back, so I assume it worked. At any rate, it doesn't look to me like you have much to lose because that doesn't cost anything to do and the seatpost certainly isn't satisfactory now.
understood. thanks a bunch! nmJS Haiku Shop

I had the same problem with my MTB Ritchey post. I wrote to Ritchey and they told me they are aware of the problem and it usually is because the bolt was not torqued properly on first installation. The rep sent me replacement parts for the top of the seat, which didn't solve the problem. I wrote back and he said I could send in the post for a replacement.

Here's the e-mail address: info@ritcheylogic.com

Good luck!

in the past I had a Kalloy post which is very similar and had this problem. Try sanding all the contact surfaces with light sandpaper, clean them with degreaser, grease the bolt, and torque it down hard. With this I never had another slip and I weigh 180lbs. If that doesn't work, something with a two bolt design may be in order
thanks, all! nmJS Haiku Shop
