Tomas. Posted November 20, 2021 Share Posted November 20, 2021 I have a SB that has been stretched to a 144x2. It mainly sees 2000'ish elevation but will see one or two mountain rides a year. (Hopefully going to McBride just after Christmas). I have been struggling to get it past 73mph. I have changed weights, springs, added fancy washers to the clutches to help but nothing seems to get it above 73mph. I have had the primary clutch at a shop to check it out and they didn't see anything out of the ordinary other than the old weights had worn into the clutch a little so they added some comet clutch weight washers to smooth out that area. The sled currently has a 21t top and a 40t bottom gear. I have a set of 20t top and a 41t bottom gear lying around. Would swapping one or both of those gears help me out? Thanks.
