full suspension single speed dh/freeride bikes

[demonprec]

who,s riding one ?? bumped into a fella with a v10 set-up as a single 20t in the rear with a 36t up front i,m considering it i,m not one for changing gears much with the stuff i ride

I've run SS on the last 3 DH bikes I've had. I don't race, and the trails that I bring out the DH bike for are all pretty steep. Works pretty flawless once set up right and opens up some budget that is normally reserved for derailleurs.

The YESS ETR-D tensioner is what I've used, but I have a Shimano something sitting in the garage that I'll probably run on the next bike.

care to elaborate on the shimano something? saint derailleur?

Shimano Alfine tensioner, perhaps. I've heard of them being used successfully.

Using YESS DH tensioner, singlespeed 2-3 seasons, much quieter setup, watch out for chainstay growth throughout suspension cycle (make sure chain is long enough, not that I had that problem, of course

running 36T and 16-18 rear cog

[Hacktastic]

The Alfine, that's it. The name escaped me.

Was running 16-18t rear and 36-38t front. And yes, verify chain growth w/o shock.

If you plan on running it for a while, get a couple backup torsion springs for the YESS tensioner. Had a couple go out on me in the 2 or 3 years I ran that setup.

I've seen a few guys running single speeds and HammerSchmidts.

this is a parts list i put together i,m going to build a new frame and plan to go single speed for what i ride i never change gears and i,m tired of it bouncing from gear to gear on some sections as i,m trying to pedal thru

ive had good luck using a rohloff thing for single speed.

Or you can do it right and ride a gearbox bike

I'm also running a singlespeed setup on my dh bike and i'm using the rohloff tensioner. you can set the chainline, but only in a very narrow window, by placing washers under the derailleur bolt.

i ride a single privot, so my choice of front chainring sizes is limited. if you go the singlespeed route, you may have to look for dedicated singlespeed sprockets with a wider base (surly, chrisking, etc.), if your freehub body is made of alluminum.

Rotec.

Saw a guy with a patriot (think it was on here) set up with boxxers and singlespeed.

He was using an e.13 guide with the cage from a rear mech mounted where the guides lower roller would be, mounted upwards so that it gave canfield/K9/Broklyn style elevated chainline. Eliminating chain growth and removing anything flapping around near the rear hub.

My buddy rode his Demo 8 singlespeed at Whistler for a week and loved it. The only reason he went back to gears was to not spin out when racing. He used the Yess tensioner.

I've been running my Voltage FR for park, xc, and shuttle DH in multiple travel settings. I went from 34-16 to 38-18 the other day to keep the upper rung of the chain off the swingarm. The chain slap was bugging me before. The gearing has been working well for non-racing fun riding.

Problems I've experienced:
-the Alfine tensioner necessitates a cog somewhat centered on the freehub body, with fine tuning possible with up to 3 thin washers. I couldn't use one on my Voltage due to the limited lateral adjustability.

-If using a derailleur, you might need to source longer H/L limit screws to keep the derailleur centered on the cog.

-The Shimano Zee derailleur is not up to the task without getting twisted. Mine got twisted on its first ride and yeah, I had more than enough links in the chain to prevent breakage upon bottom out, which never occurred.

That setup that trib is talking about above looked like genius. I don't think it would take a hit very well, though.

Been running my Transition TR250 singlespeed on and off since I got it a couple years ago. I prefer singlespeed to geared since I don't race nor do i pedal the bike up anything. My setup is as follows:

36/15 Gearing
e.13 LG1 Guide
Alfine Tensioner w/ a couple extra washers for space

Not one problem yet and scary silent, also cleans up your bars a bit.
