|  Modified trials bike gearing on a | GT Hans Rey replica Dec 10, 2001 8:44 PM | | I'm running a 24 x 18t right now I'm changing down to 16t in the back, but I'm wondering what other people use. thanks |
|  re: Modified trials bike gearing on a | Regder Dec 11, 2001 12:22 AM | | common gearing is an 18t front and 12t or 13t on the back. I'm guessing you are using the stock GT mod cranks that did not have a thread on freewheel so you are stuck with the front cog that you have.
Running a 16t on the back will give you the same gearing ratio as the more common 18/12 so you should be fine with that. |
