- Daft seatpost question?!
Hmmmm – further advice required please – bought a shiny, gold, 34.9mm Hope quick release clamp as advised above and the bl00dy thing is way too big. I’ve screwed it down as far as possible with the wee knurled nut but it’s just plain too big – the clamp closes at the back of the seatpost but doesn’t hold it securely.
The old 34mm one sits very snugly so I reckon the 33mm one would be too small. Does anyone know where I can find a quality 34mm quick release clamp? Or want to buy a slightly scratched 34.9mm one…..?!Posted 9 years ago
If it’s any help, the seatpost itself says 27.2 – does that mean I should be buying a 28.6mm clamp do you think? Just had a quick look at the wife’s seatclamp which has the same basic Halford’s seat clamp. It also has 34 stamped on it, so I’m wondering if this might be a part number rather than a size (blushes..).Posted 9 years agoStonerSubscriber
The clamp should have an internal dimension on the wider, lower, step approx the same dimension as the outside of the top of the seatube. The internal dimention the of the upper lip of the clamp should not be smaller than the outside dimension of the post.
I use a 34.9mm clamp on a Ti29 frame that takes a 27.2mm post.Posted 9 years ago
