Also posted in the endurance forum, but thought I might get find more experience with the two bikes here....

On the fence between a 2010 Epic 29er or a 2010 Stumpjumper 29er. The Epic seems to be a solid choice for endurance racing, but I also want the bike to be trail worthy. I know there are a fair number of folks racing carbon stumpjumpers for endurance events, so I think the brain equipped SJ can be stretched into endurance racing duty with the right setup.

Have an order in for the Epic, but am second guessing whether it will be versatile enough to serve as my general purpose trail bike too. Seems like the SJ might be able to handle race duties and is a great all rounder. Even though I'm a mid pack sport class kinda guy, I still don't want to feel like I'm losing efficiency. Doing endurance races for fun - probably 4-5 events a year - and usually finish mid pack in endurance races too.

Any opinions? Anyone ridden both? Anyone know the weight difference between an alum Epic and an aluminum SJ frame?

Having ridden both I bought the SJ. I can ride faster easier on the SJ and on a long ride that has to lead to better lap times.

I also found it to be a better all purpose bike.
Interesting.

Based on what I've been reading... and spending the last half of the summer on a 29er HT, I'm thinking about going all 29er. I'm a Spec fan and have had an Enduro ('00), Epic ('03) and now a SJ Expert ('08).

I don't race and am an over all slow rider, though I've been toying with the idea of doing a 24 hour race for fun. I ride mostly XC, some basic AM stuff but no hucking. I believe in "earning" my downhill by pedaling up for the most part.

With the bigger wheels, the Epic's smaller travel seems like it would suit me just fine as my all around bike. But there's always the SJ....

I'm very interested in hearing more about this topic, especially from folks who have ridden both of these bikes.

I have an 2008 Enduro, a 2007 Merida Mission (Epic Wanna be), and now a 2010 FSR SJ 29er.

The Enduro will be used for ski lift assisted DH next year, the Merida will be stripped down of all it's light parts, build back up with all the cheaper parts I have lying around and given to my son as a commuter bike. The SJ FSR 29 is now my AM, XC, and commuter bike. It feels like it does all of these things better than either the Enduro or Merida combined.

if you buy one, have the LBS check for even spoke tension on the wheels after the first ride or two.

I like that write up! I think the stumpy has won me over. I was really considering a RIP or possibly even WFO with the party pack they are offering right now, but again the specialized seems like it will be the best choice for me.

My parts pack just came in for the stumpy, now i am just waiting on a frame to arrive.

Thought I'd update since the first post. Good write up mtroy - look forward to the follow up posts. I've owned way too many bikes including several SJs (including an FSR 29er), DW-Link Sultan, HiFi 29er and currently riding an Epic 29er.

Love the Epic - fast bike, handles well, pedals better than any fs bike I've ridden. It will be a great endurance race bike and is more versatile than I thought it would be. Haters say that the brain is needed to make up for a dated design. Call it what you will - the brain works very well and the new version has a wide range of adjustment.

Still love an SJ, though! I find that I take the fast line on the Epic, while I intentionally hit the rougher line on the SJ. I hit the smoother part of rooty sections on the Epic rather than aiming for the bigger roots to use as a launch ramp to try to jump the root section on the SJ.

I think I might have to pick up another SJ 29er frame and build it up with parts I have to keep the cost in check, but the Epic isn't going anywhere! It really is a great bike.

I struggled with the decision to move to the Epic, but after spending time on both the truth is that you can't go wrong with either bike!!

So......I had an epic a long time ago - Hated the brain. Sometimes it was locked, sometimes it was open - made preloading for logs and big rocks tough cause you never knew if you had a "hardtail" under you or a squishy bike. I realize I was not on the best bike for the terrian I ride - so don't read into that.....

I know they've changed brains and made them softer for the SJ29er, but I still think this would be an issue. So I get how the SJ29er brain would feel snappy, but do you think that the SJ29er triad shock would have more of that saggy diaper feeling...or is the propedal like option on that pretty good?

I was never a fan of the hardtail feel of the brain myseld. I'm looking at the 2010 SJ comp 29er, Epic comp 29er and Gary Fisher Hi Fi 29er. I'm wondering if the longer travel of the SJ (without brain) would cause less pedaling efficiency for XC riding and climbing. Not a big fan of the triad but the pp setting should work as good as an rp23 in about the number 2 pp setting, at least you would think. I wish Spesh would get away from the proprietary triad.

While seated and peddaling on a trail, you should not notice less pedaling efficiency from the rear suspension. It needs to move to follow the trail.

While seated on a steep road climb, the front fork will cycle way more than the rear

Standing and pedaling will cause the bike to bob more in the front and less in the rear, but that is common with any bike.

So, go for the brain, once you get it set, it works very well. I have mine set to be more soft, than firm and it never bobs on the road in or out of the saddle. It does have a tiny bit of movement, but that is why I have a FS bike, I do not want to feel the road, I want to ride on it.

The great thing about the brain fade design is that it allows you to adjust from firm to fully open. You can set how harsh you want it to feel. If you want plush you can get it. If you want firm pedaling out of the saddle, then you can set it up that way too.

PB is right - you will get more bob from your fork than you will from the rear suspension - even if you have the rear end set up to be pretty soft.

Does the brain make the bike feel more harsh? Especially over smaller bumps?
No, but it took quite a few adjustments to get it there. It really comes down to one click of adjustment. One additional click of soft equals excess bob on the road, one click of additional firm = a clunky feeling on the trail.

Follow the Specialized directions for setting the brain and you will be very close to the happy medium setting.

Once you find your settings, write it down!!!

So in the case of the SJ comp 29er with no brain at all would it still be an efficient pedaling platform even with 130 mm in the rear? What is the main advantage to having the brain over not having it? Just more adjustment options than without it?

One bicycle is in the competitive XC class the other is a trail bike. Two different intended uses... If you only finish middle of the pack and don't care to move up stick with something more playful like the SJ FSR.

When the brain is locked, you have near hard tail pedaling effiecency, there is a tiny bit of flex but not enough to matter. Once the rear tire hits a bump, the brain opens up and allows the shock to work and then you have a FS bike. The firm to soft settings determine what bump size activates the brain. I am sure the Specialized site 'plains this somewhere.

Oh, and if you go full firm and lock the front fork, you have a fully ridgid 29er MTB
