We are going to the big horns at the end of the month. I ride a 2011 crossfire LTE w/ a 141x2.25" track. I bought the 63 gram weights. Is it imperative to change the helix to 36?
yep the LTD came with a 36* helix. If yours was switched its easy to change.. get a piece of thread all with some washers to compress the clutch and take the screws out of the back. Make some marks on the helix and sheaves for alignment purposes. Pretty easy swap.
