What size QR seatpost clamp

mtb.boy

I have a Kona Kula Supreme 2007. At the minute it has a boltthrough seatpost clamp. I am looking to buy a QR one.

I measured my seatube and it seemed to be about 30mm.

Tried to fit a 31.8mm one but that was too big. Should I try a 28.6mm? Just seen on the internet that there are also 29.8mm ones (which seem rarer).

do you have a front mech fitted?

if yes then it will be one of the 3 mech band sizes.

mtb.boy

Yes I have a XT front mech which fits around the seattube.

So it will be either -
28.6
31.8
34.9

(Options on Hope Seatpost clamps on chainreactioncycles.)

Also can anyone recommend a good QR Seatpost clamp?

mtb.boy

My LBS said it was 30mm dead.

I have tried a 31.8mm (too big) and a 30.0mm (too small).

Now I am pulling my hair out.


Just measured the seat-tube myself and it looks like it is 30.5mm. Does anyone in the word make QR seatpost clamps that size?

There are NONE on there the right size.

sizes jump from 30.0 to 31.8.
sizes jump from too small to too big.

ARRRRRRRRRGGGGGGHHHHHHHHH !!!!!!1 :x :evil:

there is a 30 on there.

but i would be suprised if it was a 30mm.

mtb.boy

I have a 30mm in my hand and it is too small. And a 31.8mm is too big.
