Apologies if this is considered a dumb question, but I just want to make sure.

The seatpost clamp on my bike is a bit 'roughed up' and could do with replacing. It's a bolt type clamp. The diameter of the seat tube is 34.9mm. Would I be able to replace this seatpost clamp with a 34.9mm QR clamp as a straight swap? Or would I have to buy another bolt-type clamp?

The reason behind my question: I want to colour coordinate some of the bits on my bike and have seen a Hope QR clamp that comes in numerous sizes and colours and has very good reviews.
