Fixed gear mountain bike

November 23rd, 2008

Anyone ever ridden fixed gear down a mountain? I wouldn’t dare do it on my raleigh but I think I have seen a few single speed mountain bikes around, for the life of me I can’t remember where or what make they were – every bike shop I search online doesnt seem to have any – This makes me think its not a common make that produecs fixedgear mtb’s, they might have even been bespoke bikes?

In theory I almost thing fixed gear mountain biking would work better than it does in the city, you have your long complex down hills, you could still keep the common mountain bike suspension but just loose all the gears, youd be faster in downhills and the bike would be a good 10th lighter so jumping and controling it should be easier? I know its not a very fixie mentality but I might just buy or build one, for exploration if nothing else!

    I just built up a mountain fixie about two weeks ago and it has been a bit of a rough build. I have vertical dropouts, which requires you to find the perfect gear in order to get the correct chain tension. With a 32 Tooth in the front and a 15 tooth cog in the rear, I had a bit of play in the new chain after it stretched out, so I put a 16 tooth on and it is now too tight. If, however, you do have horizontal droupouts (or some sort of sliding dropout) then you will have that part set. I am running a rigid bike with a solid fork, so the ride is a bit rough, but it was tons of fun for tight singletrack. The bike is pretty lightweight, but it is no good for downhill because if you have a gear low enough to climb with (like mine) you will have to spin like mad when you get up to speed.
    I have mine set up with an old crankset with two of the rings removed and the middle ring held on with single-speed chainring bolts (about 8 USD). I also build up my own rear wheel with a fairly cheap ($50) hub, used rim, 16 used spokes (free) and 16 new spokes($16) All in all, I probably spent 100 dollars and a few hours building my bike.
    I’ve had a ton of fun on it, including learning how to ride a wheelie (which I’ve been working on on my BMX, Mountain, and road fixie bikes for years) One of the downsides to the mountain fixies is initial cost (if you do not do the labour yourself) with good cogs costing about $25 each, a lockring at about $10, and a built 26″ wheel with a fixed hub pretty hard to find. The only other downsides are the highspeed limitation and the inability to choose where your cranks sit while avoiding obstacles on the trail.
    I love the bike for hanging out at bus stops, before and after work, and any other times, practicing barspins, cycling in reverse, wheelies, and any other creative things I can think of to try. It is also a ton of fun to ride offroad, and a joy to climb on with the low gear and the fixed-ness of it always pushing you forward whenever you think about slowing down. GO FOR IT!!!
