Hi all,
Thanks for taking the time to look at this post and hopefully provide some answers...
I have a GT Peace 9r that has a tatty seat clamp. I want to replace it with a QR one.
Does anybody know the size of these or where I might find out?
(The seatpost diameter is 26.8mm - not sure if that helps...)
Thanks in advance
my guess is it'll be about 31mm (the old clamp may even have it written on it somewhere)
or you could [url= http://www.dkg-cnc.com/sizing.html ]measure and work it out[/url] (not my site or sums)
measure the diameter of the seat tube.
Thanks for the replies.
I guess I'll take it to my lbs and get them to measure it. I don't have accurate means of doing that.
29.8 officially.
Does the post ever slip?
Should have been 27.0 apparently.
Either way, a Salsa 30.0 clamp would be my first choice.
Hope 30.0 kept slipping in my Niner (which should be 29.6 dia post).
Interesting,
I have never ridden it, just bought it second hand and building it at the moment. So I don't know if the post will slip...
SO the seatpost (26.8mm) is too narrow for the frame potentially?
AND either a 29.8 or 30.0 clamp should work? (if I find a 27.0 seatpost...)
Thanks for the advice.
GT apparently designed it for a 27.0 post, but sold them with 26.8 as that was a more common size... 😐
(Or something like that, allegedly)though.d luck finding a 29.8 clamp. I think Thomson do a non-QR version, & Niner sell a 29.6 made from Brie.
Salsa's 30.0 clamp will have no issues though.
I have managed to locate a 29.8mm QR clamp.
If I buy that and a 27.0 post, it should all be dandy....???
Thanks again
You can buy calipers for a couple of quid from Halfords and the like, and then you'll ALWAYS be able to measure stuff.
noted! thanks
Thomson do a 27.0 seatpost.
Occasional use; adjustable spanner, adjust to fit the tube, ruler. There can be some play/inaccuracy in an adjustable though...

I was been only half sarcastic as I've learnt not to trust any manufacturers stated measurements, especially where seatposts/clamps are concerned.
