Mine are just over 130mm and I went for the 150mm (as Mr Gib says above they suggest going for the widest you need as slightly too wide is better than slightly too narrow). 100mm would suggest a 12cm version which is damn narrow but if that's where you are....Schadenfreude wrote: ↑Wed Mar 20, 2019 3:32 amI'm planning on trying the SQLab Ergowave 612 Active soon. Someone mentioned BIGGRIDE in Australia, funnily I just ordered the fitting kit from them.
What do you sit bones measure at? I have had mine measured on an Ass-o-meter at 100mm - I don't really want to order anything to wide as I have found wider seats uncomfortable in the past. e.g. the Fizik Aliante - the wings just dug into my thighs.
See what the fitting kit says (also to be honest you can measure them easily enough with any sort of card etc.)
