Two Bikes on Direct Drive Trainer
Hello all!
First Post,
My wife and I are looking to start indoor biking on a trainer. Going with a direct drive. I am looking to make for easy bike switches. Currently the bike drive systems are different.
My bike is using:
Shimano Tiagra 9 speed with 11-25T cassette
My wife's bike is using
Shimano Sora 9 speed with a 12-32T cassette
How would I go about creating a comparable system for indoor? Is it as simple as putting a cassette on the bike (like a 11-27T) and attach bikes or will i need a different derailleur and chain on one bike to accomplish this?
Thank you all in advance!
