53T on Shimano Octalink Cranks?
I was wondering if there is anyway I could run a 53T chainring on my cranksets...they're Shimano FC-M445 Hollowtech. I want to remove the 44 and replace it with a 53T, but if I can't...how big can I go?

Shouldn't be a problem with the crankset, as long as the bolt pattern matches. Chainstay clearance may be an issue depending on your frame. You'll need to get a new/longer chain.

It is a problem with the crankset as the bolt pattern is different. 48 is a big as you can go, and it could be tough to find one. |
Not only that, but your shifting might be compromised. Going to a 48 tooth will require you raise the front derailleur. Then when you shift back to your (I'm assuming 32 tooth) middle ring, it'll drag on the back of the derailleur cage. This will be even worse when you shift to the granny gear (if you can at all).
If you want to improve your gear ratio for riding on the road, you are better off with a road cassette vs. a front chainring. |

it's all about a higher top speed, I actually would like to go to a road crank on the bike if at all possible. the 28/38/48 has been mentioned to me.

You're still better off with a new cassette. The bigger chainrings might hit your chainstays. Mountain bikes need more tire clearence and thus widen quickly away from the bottom bracket.
I'd get a tighter gear ratio for the rear vs. the new cranks. But that's just me. A guy who's been a bike mechanic for 20+ years (off and on). |
I have an 11-32 in the back...I'm quite content with it, what if I went to a road crankset, like a 105 triple?
|
Without actually mounting it on your frame, I wouldn't even venture to guess, but yeah, a triple should work. You can also find some mtn cranks in a standard spider (not compact) that are 46/34/24.

sounds to me like you should get a 'cross bike

well there is clearly alot to that story i don't know.
Still doesn't make sence to me to mess with a mountain bike when there are tons of good off-the-rack cross bikes. |

Didn't the road forum just get through roasting some guy called 53-11AllTheWay saying that unless his name is Ulrich he doesn't need that gearing? Somehow I doubt you do either, your current 4:1 top gear ratio would be plenty high enough for any kind of sustained speed. I can only stay in my 4:1 top gear on my cross bike for an extended period if their is 0 headwind and I'm really pushing it.
Can bigger guys just push bigger gears at much lower cadence? |

There are some guys around that will make custom chain rings any way you want. A fixie friend of mine had a really strong ring made for his "Poojoe". As for the derailer problem. You could go to a road front, bottom pull and use a cyclocross pull reversing pulley to work on a mountain frame. It's some rigging to go thru but it would work.

as far as mr. 53-11 I'm not saying that this is the ONLY gear I will be using, I just want the ability to jump into a higher gear, I constantly find myself having to use the top chain ring as my riding is improving. I don't like spinning high cadences, I'm not trying to break any speed record...it's just a question...I'm not asking to get flamed here, just looking for info.

Just change the rear cassette.
