|   Much difference between a 175 and 180 crank arm? | MikeS
Sep 3, 2002 12:02 PM | | My legs have gotten a lot stronger and I find myself riding too much in the big ring small and gear on flat rides. I'm wondering if a longer crankarm would give me the resistence I'm looking for. |
| Not for what you are wanting | shiggy
Sep 3, 2002 12:10 PM | | The longer cranks can let you push a bigger gear and it sounds like you are already using your biggest gear.
Just learn to spin. It should not feel "hard" the spin along the flats.
BTW if you are able to spin out a 42x11 gear on the flats you should turn pro. |
| Hmm | MikeS
Sep 3, 2002 2:18 PM | | Thought I was spinning, but maybe I'm hot when I'm trying to go for max speed. What would be the sign of someone not spinning? A herky jerky
motion? Like the ride having a bit of a stop and go look because the rider is just hammering downward on the pedals? |
| By "spinning" I mean... | shiggy
Sep 3, 2002 3:31 PM | | ...a smooth, even pedal stroke at 90-110rpm. 90 rpm in a 42x11 gear on a mt bike is over 26mph. If you can maintain that speed on the flats, alone, you can give Lance a run for his money. |
| shouldn't it be in relation to your legs' length? | older guy
Sep 3, 2002 12:34 PM | | I believe a crankarms length has something to do with your leg length. You can always change to bigger chainrings if you feel the need to go faster. |
| Agreed - goo bigger ring(s) but you may need 2 upgrade your FD | Scott_in_Jersey
Sep 3, 2002 12:45 PM | | I have both 175 & 180x110BCD (std) cranks and the only difference I can tell is the improved leverage when climbing and the worse ground clearance when cornering with the 180s. Switch up from a 42 to 44 outter ring and save some cash. Good luck. |
| Longer crank=easier to turn the pedals..... | FreeRangeChicken
Sep 3, 2002 1:39 PM | | Longer crank will provide less pedal resistance, not more. I'd consider changing chainrings or cassette. |
| 5mm | duh!
Sep 3, 2002 4:52 PM | | duh! |
| Actually, the diameter of the circle increases by 10mm. nm. | Fujiman
