Seatpost Clamp

[rookienjules]

Bit of a dumb question but I have foolishly over tightened the seat bolt clamp on my Raleigh Airlite 400 and it has broken. The seatpost is a 27.2mm but the seat tube is 35mm in diameter, so my question is, when buying a seat post clamp which size do I use? Also I am looking to replace the seatpost with a carbon one, do I need a special seatpost clamp or not?

Thanks

Jon

You need a 34.9mm clamp. Not aware that you need anything special if the seatpost is carbon, but you could maybe do with knowing the right torque setting before you fit one!

Thanks for that, and yes I will be more careful next time!
