I saw a Rig in person today. Sweet. I'm very tempted to get one. They checked with Fisher and they have them available in 21".

I'm worried a bit about the eccentric bottom bracket. Folks at the shop said one of their guys who has one had his EBB seize up on him. Said it fills with water. I plan on riding all winter, I don't want hassles.

Also worried about rear tire clearance. It looked good at the shop with stock 2.2s on it, but I've read of some problems. I like FAT tires and don't want to buy a bike that I can't put 2.3s on.

Anybody have info....???

The guys at the shop obviously don't know to wrench. Many people here have complained about the EBB having very little or no grease from the factory (mine had almost none). Buy the bike, take the EBB off, grease the sh!t out of it and you wont have any problems.

An Exi is a tight squeeze in the Rig, but if your wheels are wound tight, and they're straight, you can squeeze the in.
Also, as Big Drunk has stated, EBBs need a little love, but I doubt you'll have issues with it.

been riding the heck out of an xl rig since early may and love it. the bb does creak from time to time, but to tell you the truth i haven't even bothered to take it out and grease it yet cause i'm having too much fun riding it.

Rig Love

I ride a small 05 rig.

2.2 or 2.3?? The difference will not really matter. I run a 2.2 tire at 30 psi and i have not had any problems with clearance or lug shearing.

grease that EBB. I echo what was said about the shop and seizures. you should probably find a new shop if that is the answer you got.

if the EBB was a bad idea, it would of disappeared years ago. take care of it, like you would the rest of your bike, and you should be golden all winter long.

fills up with water?

seriously?

what would it take, condition wise, for that to really happen.

ride the rig and enjoy it. don't sweat the technique.

peace

I've got a rig and absolutely love the bike itself, but have had a bad experience with the EBB. One day when it was wet and muddy it slid laterally (side to side) on me without me knowing it. And then all of a sudden I feel my right crank arm start hitting my chainstay as if the crank arm had bent. I pull over, look down and see that the EBB had slid from the right (drive side) to the left in its shell. This caused the chainring to cut into the chainstay just like a buzzsaw (without me realizing it). There is no snap ring or ridge on the shell to prevent the EBB (and chainring) from sliding into the chainstay. Now the chainstay has a nice slot in a max stress area, just a matter of time before it breaks I guess (this is a nearly new bike too).

And the EBB was not loose or improperly tightened either. It was properly torqued down before this happened. And after it happened, I recentered the EBB on the trail and tightened it again almost to the point of snapping the tensioning bolt. But again it slid from right to left within a matter of minutes as I was riding out of the trail. It got to the point where I had to stop about every five minutes to keep loosening it, readjusting it and then retightening it again as I rode along. It sucked, HUGELY. Anyway, later I removed the EBB from the shell and because it is totally unsealed it had a lot of wetness and dirt inside. I cleaned everything out with windex so it was surgically clean. I also noticed there was a bit of black frame overspray paint on the aluminum wedge which I thought may have lessened the amount of friction it could hold. So I wire brushed off the paint as an additional precaution. Then I reassembled everything, set chain tension and tightened it back up. I have ridden it about 8 times since then and it hasn't slipped since. Apparently there is a level of water/mud contamination the EBB cannot handle without slipping. Combine this fact with the fact that it is totally unsealed and the result is that the EBB must be cleaned out periodically or it'll probably slip again. And to clean it out you have to remove one of the crankarms, which if done excessively can wear the splines or square taper interface on the crank.

Another downside is that the EBB creaks and it creaks a good amount - pretty annoying. It seems as if greasing is what people are recommending to stop this. But in my view, if it slipped with mud and water in there, I would think there's a good possibility it might slip with grease in it as has been suggested. Also, the fisher EBB's tensioning allen bolt head can get partially or wholly plugged up with mud (because it's down there in the mud with the rest of the unsealed EBB). Combine this fact with the fact that the bolt is stowed away behind a chainring bolt, you have very limited access to it, making it hard to clean out before inserting your allen wrench. And if you can't get full engagement on your allen wrench, you're much more likely to strip the bolt head, making it impossible to loosen or tighten the EBB again - which can be a real problem miles away out on a trail somewhere.

This is my first EBB experience, previously I have used track ends (horizontal dropouts) and various converted chain tensioners. The EBB has a few advantages, but with this buzzsaw/creak/contamination experience, my next frame will be a return to good ole' track ends. Overall I'm not impressed and when viewed in the pros/cons balance that all tensioning systems have, this one certainly ain't on top.

I have an 06 that I picked up back in December and rode it all winter in the mud, snow & slop. I have had no problems with the EBB, like said before just take it apart before the first ride and slather the EBB and wedge with antiseaze and you should be good to go. Tire clearance is adequate with the 2.2 but not much more, but is sounds like many other people have been able to get an 2.3 in there with no problems.

To ease your concerns

I got an '06 Rig last september when they first came out. It was my primary training bike throughout the winter. I live in Minnesota and was constantly riding through 4-6" of snow and a good amount of rain/mud (since winter is only so good anymore).

I've never had the EBB move on me, or fill with water. In all reality, if you have it torqued correctly the EBB will seal out any water or dirt from getting inbetween itself and the frame. I admit, the outside gets pretty dirty. But if it's tight, there's no space for water to get in there.

I really like the EBB and have an easy time adjusting it for different gears. I definitely prefer it over chain tensioners. I would like to try an eccentric hub though, that seems like a good idea.

In terms of tire clearance, I have noticed wear on the stays when I ride in muddy conditions. I also see no reason to run a tire bigger than the AC-Xs stocked on the bike. The idea of a 29er is to get hook up from the longer tire footprint, not a larger tire. Plus, big tires are friggin slow.

I have had my 2006 17" rig for over 2 months now. The bikeshop used anti-sieze on the EBB and I have adjusted it since with NP. I run a 2.3 exi with room to spare. I must be living right, cause I have had no problems. I love the bike too, its real fun to ride. Good Luck.

Love the Rig, but have some issues

Been riding my 21" for about 2mo to work as a commuter with slicks, put the stock bontrager jones 2.2 back on 3 or so weeks ago and have had 10ish rides offroad of ~15-20mi ea. A few things:

My frame has rub marks due to a lack of tire clearance. The inside of the left rear up by the bb hub is rubbed completely through the clearcoat, paint and is now into raw metal. I never heard a thing and just discovered it tonight. I have no idea if this is a bad bad thing or just a bummer that the bike can live with (anyone have thoughts?) Again: stock wheels and tires. I'm 6'4" and ~200lbs, so I'm bending that frame when I stand up and crank. If you want to know if you'll do the same just go find a rig your size, stand up on the left pedal and tilt the bike away from you then bounce up and down. You'll see the tire clearance change.

Next up is the EBB: I haven't messed with it at all until tonight either. Finally have stretched the chain enough to want to move it. I tried and tried and tried but the thing is stuck very tight and I can't budge it. I'm off to the LBS to ask for some help tmw.

All told I LOVE the ride of the bike, everything about it is just sweet and the geometry is the best I've ever ridden on. I reccomend for the ride, but maybe maintainance is becoming a concern???

That's pretty funny! You don't have your EBB installed correctly (lock bolt on drive side) and you do not operate/maintain it properly by not keeping it well lubed with either grease or anti-seize. Then complain that it does not work well!? Hmmmm.
In order for the wedge to slide as it is being tightened it HAS to be well lubed. That means inside and out of the wedge, not just the outer areas! This also will eliminate all creaking.
If you leave that thing dry, even without mud or water and corrosion, you could put 500 ft. lbs. on the bolt and the wedge will not slide and tighten the EBB properly. Sure, the bolt will "feel" tight But that wedge will not be making proper contact and...Well, you have described the results to a "T".

Using grease or anti-seize (I use "never seize compound") is not a recommendation, it is REQUIRED for proper wedge type EBB operation.

Do yourself a favor, take that thing out, clean and libeally lube everything inside and out of the ebb/wedge including the bolt threads. Clean and lube the inside of the BB shell. Then install it properly with the tensioning bolt head on the NON-drive side.
Then enjoy a solid creak free ebb experience! ( I also find that after a couple of ebb adjustments that a re-lube keeps the creaks away)
