180mm Cranks
I had a friend ask me the other day about 180mm cranks. Why me? He discovered I run them on my 29er. Well, not only do I use them on the Soulcraft, but also on my ‘cross/commuter and my townie bike.
When I got my P.O.S. townie it came with 180mm Cook Bros cranks. I’ve always ridden 175s, so I thought it would be interesting to bump up a notch. Please keep in mind folks I’ve got long legs. The stomping power with the 180s on there was awesome. I’ve got long levers to begin with and this just up’d the ante.
Peddling through corners can be a problem, but that’s typically a no-no regardless of crank length – especially with flat pedals. I’ve had a few close calls there, but nothing major. I’m pretty conscious of it now and try to relax and just coast through the corners like a good boy. My townie is a single speed, not a fixed gear. I would never run 180s on a fixie – I recommend the shortest cranks you can find for that application.
Several years ago a friend was getting rid of a set of 180mm Race Face turbine cranks + TI bottom bracket for a good price. I snapped those up and stuck them on my ‘cross bike. I’ve always been leery of trail riding with long cranks. But thought I’d give it a go on the ‘cross because, as you know, ‘cross racing is mostly flattish and the turns are usually pretty hairpin – not a lot of pedaling there. I’m really liking them, having had them on there now for a few seasons.
And now the mtn. bike. Again, I had never really considered running 180mm cranks on a mtn. bike because of the clearance concern. When I got the 29er I found that my clearance was going up about 5mm. Viola! I had an opportunity. Another friend had another set of the exact same RF cranks + BB and he too was willing to unload for a good price. Maybe I should have stopped there, with people ditching their long cranks, but the thing is, they both had them on 26” mtn. bikes and they’re both smaller riders – not by much, but smaller none-the-less. I’d have to say it’s a pretty sweet setup on the 29er. Bigger is better all the way around. I hung up a little on some technical climbing singletrack in CO, but I doubt shorter cranks would have been much help. I definitely have to stay over the cranks – once I get behind them it’s a suffer fest. And I still have to watch the uphill pedal stroke on contour trails, but I did before anyway.
So there you have it . . . my two cents about 180mm cranks. It’s not something I would preach, but if you're built like a pole (like me) and you're at all curious, I would try it. It might work for you.
