Ive had 2 different types, 25.0 and 27.2. No worries i thought. My wife has an Avanti corsa, it takes a 26.8mm seat post. Is that a normal size. Stupid me spent 20 mins trying to jam a 27.2 in to it. Then another 20 trying to get the bugger out! (all the time thinking 'it shouldnt be this hard, just stop'😉 but i didnt derrr:p
Is this a normal size that everyone has heard of? Has my head just been in the sand?
