So built a little SC Bullit, do some freeriding and started doing some downhill as well. Currently running a dual ring up front 22/36 and a 9 speed 11-26 cassette in the rear.
Thinking about changing to a single ring up front (36t), and then going with either a 12-36 cassette or a 11-34. Was playing with a gear ration calculator (Sheldon Brown's Bicycle Gear Calculator), and here is what the gain ratios would look like...
22 36
11 3.9 6.4
12 3.6 5.8
13 3.3 5.4
15 2.9 4.7
17 2.5 4.1
19 2.3 3.7
21 2 3.3
23 1.9 3
26 1.6 2.7
Current
36
11 6.4
13 5.4
15 4.7
17 4.1
20 3.5
23 3
26 2.7
30 2.3
34 2.1
11-34 9 Speed Cassette
36
12 5.8
14 5
16 4.4
18 3.9
21 3.3
24 2.9
28 2.5
32 2.2
36 1.9
12-36 9 Speed Cassette
Thoughts? What ratio should I go with? or should I just stick with the dual ring setup?
