Hi guys
I have a Thomson seatpost which is 28.6 and my frame takes a 30.8. I've searched the net and can't find the correct shim size so was wondering if anyone could offer advice?
I know there must be alternative methods i.e. using other size shims to fill the gap but unfortunately I have dyscalculia (number dyslexia) so can't work it out.
Any advice would be very much appreciated.
Cheers
I have a 28.6 Thomson too - if you do find a specific shim I'd be interested to hear.
I AM ALSO NOT QUALIFIED TO ADVISE (...however 🙂 )
I suppose all you really want is to add 2.2mm to the diameter, so a 26.8 to 29.0 or a 27.2 to 29.4 might be OK
I guess the shim would "open out" a bit, leaving a wider gap than is ideal - so perhaps 27.2 to 29.4 would be the better choice, SLIGHTLY
(not sure this exists though, closes I can see on CRC is 26.8 to 29.2 which might work or could be a bit too tight)
Hi Mike
Thanks very much for your advice.
I've just ordered a 27.2 - 29.4 from Evans. I'll report back to you when it arrives and I've fitted it. If it works - great, and if it doesn't I'll have to resort to using cut down beer cans!
I'll keep you posted.
