Yes, however, most mountain bikes have vertical dropouts which do not allow you to slide the wheel forwards or backwards to adjust chain tension.

They are not required, they are just one way of getting proper chain tension with vertical dropouts. Another more elegant way is to use a White Industries Eno hub, but they are pricey. The best way is probably to get a frame with horizontal dropouts, or track forks so you can slide the axle to adjust chain tension. All SS specific frames have some way to adjust the chain. most of them use Track forks in place of horizontal dropouts, but a few have eccentric bottom brackets which is a very slick solution. Pricey, but slick.

These are nice because they can come with derailleur hangers too, incase you want to revert to gears.

the sliding dropouts or ebb's are nice too if you run disc brakes on a ss.
i have the iro highlander, which has trackends... thus, no tensioner required. however, i just put a chain tug on because i kept pulling the wheel forward and dumping my chain on fast steep ascents. not that i don't love being sprawled out like a turtle in the middle of the trail...

Thanks....I read about horizontal dropouts on SS roadies but didn't put 2 and 2 together. And while I looked at 200+ pages of fixie photo's I noticed some MB's had tensioners and others didn't.
Sucks that roadies and MB's are lumped together in the fixie photo thread.

They also help to keep your rear wheel from sliding forward in the dropouts and throwing your chain when you mash down really hard on an ascent. If you're a heavier rider, this is a frequent problem.
EDIT: Also, if you use a smaller cog (i.e. 16 tooth to a 32t chainring), that torque can screw with the rear wheel, too.

I think what you're talking about should be called "chain tugs", at least in the realm of SS bikes. Just an opinion.

(btw, I love the Inbred. Long top tube, short stem, feels like a BMX bike...)
