As much as i like the SE seat it does sit you an inch lower to the ground than the T100 and I've noticed I'm rather tucked up on the legs/knees front on the SE even though I'm only 5ft 10, a friend has a standard bonneville and has just spent over £200 on a www.britishbikebits.com
retro seat. I'm a cheapskate and can get a T100 seat much cheaper.
I 'm assuming the T100 fits the SE, but can anyone say for sure it does, or has fitted one???
