    Will "road bike" cranks work on a mtn bike?

    Bank error in my..........no. Never mind that.

    I have some money, and I was thinking about upgrading the cranks on my SS. I currently have some RaceFace "Next" cranks that have aluminum shrouding some carbon, but they are on a tapered BB.

    I was thinking of converting over to the Mega Exo bottom bracket, thinking that would save me a little weight.

    A LOT of the cranks I see on a certain auction website are stating that they are "road bike" cranks. I know I currently ride with 180 mm cranks on my geared bike, and most of the "road bike" cranks I see are 170, 172.5 and 175 mm. Is that the difference? Is that a BIG difference?

    Yea or nay?

    Should I give the money back to the bank, or take the crew out to dinner?

    Thanks!

    Is there something simple or obvious that I am missing? Or is this something that we just don't know?

    My crew wants my bicycle stable to be the gnar, so getting an epic set of cranks is paramount.

    I passed over this thread because I figured someone more knowledgable would come in with a definite answer. As far as crank arm length, I know that's just a matter of personal preference. I've seen mountain bikes with crank arms as short as 165mm (for a young-teenaged kid to ride an adult bike as he grew into it) & as long as 180mm like your current setup. I believe mine are 175 & they's perfect for my riding.

    I think the main concern with road bike cranksets should be durability. If you're just riding fire roads & MUPs, I wouldn't worry, but if you're riding singletrack I personally would trust roadie cranks to withstand the abuse. Someone more educated could come in & correct me, but given the nature of roadie bikes (weight>strength), I'm pretty confident in my answer.

    Appreciate the insight about the crank length.

    I don't think you would be happy with the gearing options that you would have with road cranks.

    I assume a triple would work, they are 10sp but I think they work with a 9sp chain.

    http://www.ebay.com/itm/SHIMANO-ULTE...item5891b31ee0

    Even though 5mm doesn't seem like much it seems it is quite noticeable. 175-180 wouldn't be too bad but going down to 170 would be a huge difference.
    I think the above is made in 180 but harder to find.

    But if you want to go really gnar!!!

    On one of mine I went with red and gold! I think those red chain rings are CRAZY.




    It now has a fox fork (white) and a red KCNC stem, Red CK headset and red seat post clamp.

    That thing looks pretty damn nice! The gold color of the frame and cranks seem to be spot on! I *REALLY* try to be a "Function over Form" guy, but I have to admit that I love the looks of my Soul Icon, and I put some white SPD pedals on it (to play off the white "Soul" and "Icon" graphics), and I cannot help but smile a bit when I look at it.

    Seems like I missed yours is a SS.

    Well I did get a little carried away when I found the limited edition Magura HS-33's, with gold levers and brake boosters, and red wear adjuster knobs.
    And the red titanium Wellgo pedals have gold titanium axles, go figure.

    I think its disgusting and terrible how people treat Lance Armstrong, especially after winning 7 Tour de France Titles while on drugs!

    Gold dual crown forks are the greatest thing ever. As for color schemes in general, Cherry Red Metallic & Pearl White are unbeatable on just about any bicycle (& some cars) IMO.
