I found a crack in my 1 year old road bike frame which was fitted with 10speed Tiagra. The frame was covered under guarantee but as it was no longer available the shop supplied me with a newer better model with 11speed 105. Happy days.
My main wheels are 11speed compatible so that is great but the wheels I use on the rollers are only 10speed compatible (Not expensive but only have about 120 roller miles on them) Not sure if all the options below are possible but could do with some advice
Options.
1. Sell the wheels and get new 11speed compatible ones with a new cassette.
2. Try and replace the freehub body/axle length to make the wheels 11speed.
3. Use a 10speed cassette with 11speed components (sounds risky)
4. Buy an 11speed cassette and install on the 10speed wheels minus one cog and adjust limit screws (sounds risky)
5. Sell the bike, the wheels and the rollers and take up another sport as I normally break things when I mess about with them.
Open to any other suggestions if there are any?
Cheers
