    Single Speed a 2007 Spec EPIC?

    I'm tiring of the norm and want to start challenging myself a bit more. I've been doing some 30 milers on one gear (40/21) on my 2x9 setup just to test my spiritual side. My racing season was ended early due to the H1N1 forcing me to miss the first several races of the season, so I figured now's a good time to change it up a bit before spring time racing comes around.

    I've read a few folks have SS'ed some Full Suspension bikes, and even have one reference of an older Epic. As far as I can tell with the shock off, on the 2007 EPIC Rear Suspension, the length from BB to Cassette is relatively fixed at 0-2.75"'s of travel. After 2.75"s, it changes a bit, thus probably no "magic gear" will fit the bill here. However, I'm going to mock it up and test some on my backyard trails.

    I have pretty light setup as it is with a small frame coming in race weight at a few grams under 22lbs. I run a locked out SID in front and really tight Brain Setup in the rear. Without the shifting gear, I think it would be a fun ride. I'm a short guy 64.5", and haven't found a 29"er that works for my geometry needs, so I thought I should discover some 26" options like my own ride first.

    My question is simple. I ride and race some rough trails and would be concerned about maintaining good chain tension. I've seen some tensioner units like Rennen and Surley. What are my best options for a 2007 Epic?

    I did break a derailleur hanger not long ago, and had to shorten the chain on the trail and ride home SS. I never dropped the chain even though I was blasting my normal lines, enjoying every minute of the effort. Recommendations welcome and appreciated.

    you can only try. I did on my FS and turned out the chain grow way more(than I had hoped) as the suspension cycled thru the stroke so no go.

    this will work if you use a tensioner.

    this one seems to work well:

    I have a similar one on my Salsa single speed soon to be 1x6, made by ROOX from Europe. a friend has a 2008 Epic with a Paul Melvin and that seems to work great for an expert/semi-pro guy.

    The surly just doesn't have enough travel to take out the slack during suspension movement as well as bouncing around on the trails.

    I'd be careful about gearing. I would think that mashing too small of a ring up front would produce less than optimal performance out of the fsr suspension.

    I saw a guy using a Surly tensioner on an Epic. Whatever year they made the special edition pink one. He won a 19-29 Sport race on it.

    Thanks for all the input thus far guys!

    One of my buddies has a Surly that he pulled from his Vertical dropout bike before he sold it. He has a real SS frame now. I think I'll give it a try for some testing.

    Both the Yess Units look pretty nice. Even though I have a 2x9 (40/29 and 12-27), I can't remember the last time I had it in the small chainring except on the stand. My legs seem to be happiest in the 40/19 and 40/21. I'm faster on my favorite mixed sections running 40/19 as verified this weekend even though a few steep sections took some "manning up!"

    OH!...almost forgot....the YESS tensioner rigged to my RX would only accept an 18T as the biggest rear cog.....FYI

    Smile SS Epic

    I would try a Paul's Melvin tensioner, I used one on my SS Epic (2005) and it worked great. Here is a link to a past post w/ photo of the Epic:

    http://forums.mtbr.com/showthread.ph...95#post3351395.

    Unfortunately the bike met my parking structure via the car rack and am no longer riding it, Here is a link to the FS SS I am riding now:

    http://forums.mtbr.com/showthread.php?t=373949.

    I took the tensioner off and found a magic 32:18 gear, and switched out the rear shock with a Cane Creek Cloud 9. With 4" in front 5" suspension in back, the bike rides great as a SS.
