did some math and figured out that 15/49 has 20% less stiffening of the suspension from chain torque than 13/49

needless to say my next sprocket combo will be geared high, hopefully i can notice a difference

did a bunch more math and i figured out its the ratio that matters, it dosent make much or any difference if youre running 15/52 or 13/45

From 13-49 to 15-49? good luck on the slow speed verticals! great in the desert though.

bigger front sprockets help to a point...........

have you every tried the technique of chain torquing quite effective
