Just a quick one - the seat post clamp on my bike broke as I adjusted it this evening and I need a new one. The seat post diameter in the bike's spec says it's 350mm - is there a specific size seat post clamp that I need? Not had to buy one before.

Thanks.

350mm is more likely to be the length of the seatpost, not the dia.

You need to measure the dia of the seat tube on the frame - that's the way the clamps are measured (and sold)

Seat post clamps are very finely engineered (they come sizes varying by 0.1mm) and so you need a very precise measuring tool. I'd check the clamp you broke and on the inside there may be a size printed.

Hope do several sizes to cover beefy DH frames, but they certainly ain't in finely engineered 0.1m increments - 28.6, 30, 31.8, 34.9, 36.4 and 38.5mm.
The 3 sizes mentioned in the post above will cover 99% of frames out there
