My Rex was purchased with the Gearing 15T/39T.. the smaller 15 at the front seems to be wearing the Seal guard.. would changing it to a 17t improve the clearance?...to get same gearing I would need a 43 at the rear..any Feedback... Thanks

there are a number of gearing options people have tried

You will find some stuff if you type gearing in the search box

Also this thread is handy

Thanks for the Feedback.. Seems 17t/42t is the go...Maybe less Seal Guard wear with this combo..
