Hope Seat Clamp & Bolt - 30.0mm

Another small part to have a redesign this year. The collar on the seat clamp is now a universal style - meaning either bolted or QR can be achieved on the same collar (the QR does not come with a bolt, and vice versa).

Rated 4.2 out of 5 by 24 reviewers.
Rated 5 out of 5 The Only One I Use I use my mountainbike for commuting and trail riding and need a bolt through seat clamp so my saddle doesn't go missing when the bike is locked up. I am not light and need a clamp which will not slip, I have used these on many bikes now and have never had a problem, it really is a fit and forget part. I thoroughly recommend this clamp. 03 October 2014
Rated 3 out of 5 by fancy little tweak for your pleasure It is light as foil but do the work. The only bad thing is it seems bit smaller then my previous clamp (although both have same sizes 34.9) 26 September 2014
Rated 5 out of 5 by The best seat post clamp on the market I have two of these clamps currently and had one on a former bike. Decided to use stock clamp on my new Santa Cruz mistake had to overtighten and still creeks time for a third hope. The hope is light and tall requires a lot less torque and clamps better than its competitors due to height. Only thing on market that is close is salsa which is double the weight and requires more torque to clamp as well. I have one on wife's bike and if it diss not get tightened enough starts to slide. Do yourself the favor buy the hope and forget it is even on your bike 25 September 2014
Rated 5 out of 5 by Clean, light and tight Light, strong, easy to install, beautiful finish, simple, fits well. 04 August 2014
Rated 4 out of 5 by Quality product Another great product from Hope. Shame it's not all this cheap. 11 July 2014
Rated 5 out of 5 by Great Quality Looks bling on the bike and good quality as with most of Hope products, have had no issues 17 June 2014
Rated 4 out of 5 by Ugly, ugly thing Hope kit is great and almost always ticks all the boxes. This clamp is functionally perfect but only a mother could love it - it is almost too ugly for my frame. If only Salsa did purple... 06 June 2014
Rated 4 out of 5 by Great Looks Quality bit of kit, looks great...however, you're paying euro per gram, approx, so a bit steep for a small piece of aluminium Having said that, it looks cool, works well and is beautifully machined and it's the only one that I could find that gets near the 36.6 diameter I needed!! 22 May 2014

Answer: 
this has nothing to do with your stem, its simply a clamp for your seat tube, so that it holds your seatpost in place. to find out what size you need you can use a shifting spanner(must have mm markings on the jaws), simply open the spanner, place it around your seat tube, lighltly clamp it and then pull it off and check the diametre on the spanner measurment

Answer: 
You mean SEAT POST is 31.6mm. Stem is the bit that holds your handlebars. 31.6 is pretty a common diameter, just bear in mind, that's the seat post itself, the clamp needs to go on the outside of your seat tube. So the clamp measurement you need depends on the thickness of your frame. For aluminium and carbon the general rule of thumb is add 3mm to account for frame thickness, thus you'll probably be wanting the 34.9 clamp. Some steel or Ti frames are thinner but even then, 34.9 ought to cover it as they can be tightened a fair bit.
