Schwinn Peloton Seattube Diameter: What's the Man. Spec.?(4 posts)

Schwinn Peloton Seattube Diameter: What's the Man. Spec.?commuterguy

I have had this bike for about 2 years. It's a great bike, with one little problem that recently became of bigger one: the seatpost tends to slide down the seat tube. For a long time this happened gradually, and to prevent it I probably overtighened the seatpost binder. Recently, this problem became acute (the seatpost wouldn't stay up at all), and close examination of the seatpost revealed that it appeared to be indented (very slightly) where it touches the seat collar. Also, the seatpost collar has always seemed too small--when it was tight enough to hold up the seatpost its ends were basically touching.

I took the bike to an LBS, who measured the seattube at 27.0. (This is consistent with the declared size of the stock Ritchey seatpost.) However, this seems to be a very uncommon size seatpost (the only 27.0 seatpost I have found is an $80 Thomson mountain bike version at Performance and CC). I want to check the manufacturer's specs for a 58 cm frame, but Schwinn doesn't post it at their website and its "ask schwinn" feature is under construction.

How else can I get this info? Can I safely use a 27.2 seatpost in a 27.0 seattube? Are Thomson seatposts worth $80? (And an extra 80 mm of length and weight?)

Thanks in advance for any help you can provide.

I have the same bike and recently posted a similar question. Based on the responses, I got the Thompson seatpost. But, I ordered a road version (in silver to keep with the Peloton's "old school" looks) from my LBS. I believe the only difference is the length.

Thanks for this response. Could you tell me the size of your new seatpost, and your frame? Did you replace the seatcollar as well?

27.0, but I had to special order it.
