the fit makes a difference if it is very different (eg. road vs tt position), it will not matter much if the bike is a bit small or large.
get another trainer and train together on properly fitting bikes?
p.s. there might be a gap in the market for a "turbo-bike", a simple sturdy frameset with easily adjustable saddle and handlebar positions, similar to spin bikes.
Yeah that what I suspected. I'll stick with the set up as is. A quick swap out of seatpost/saddle and pedals is easy and off you go.
There is a 5 inch height difference between us but with slamming my saddle right back and the post raised way up its not too bad. Ideally I'd have the saddle back further but can still tap out a rhythm with my arse hanging off the back.
I don't really want to goto that extra expense of two turbos TBH zigzag.
Plus we have the set up tucked away in a nice cozy corner. No room for two setups.
Absolutely on the turbo bike. It would be so much simpler. Like one of those contraptions they use when you go for a bike fit.
