Strength:

4 brearings!

Weakness:

Too short -- only comes in 113mm

Had to really torque to get the cranks to seat -- 55 ft-lbs! (Race Face said to go as high as 60, but seating was a must). Many torque checks over the first 100-200 miles were needed and they creaked during that time. But, once they seated fully, they've been quiet and dependable.

Had a real problem with the chain line. The left side can't move in because then the crank hits the swing-arm pivot, and I really need to move the right side out (drive side) to get the middle->small downshift reliable. I had to bend the outer edge of my *XTR* front derailleur in to get it to downshift at all -- IMO, you shouldn't have to bend expensive metal to make it work. After lots of careful tweaking on that cage, it's "ok". They really need to make a 116!!!

Rating's based on RaceFace's only making it in a 113 (and I believe a way too wide 135) and forcing everyone to follow their lead.

Strength:

Well made and clear instructions.

Weakness:

Weight... Not as light as a TI square one

This is a really nice piece. Even just sitting on my desk, everyone had to pick it up and look at it, but hey, what do you expect when you have a beautiful chunk of steel topped with two gold anodized aluminum cups.

Even with the really good instructions I had a question. I called Raceface and got an instant answer and when the previous reviewer said it took a special tool to install. Well, all ISIS bottom brackets take it. Hey, it’s only 10 bucks, so just drink a few less beers.

One of the best features about this is the adjustable chain line and it looks easy to rebuild, but with the really good seals that Raceface uses I don’t think I will be doing that soon.

Overall, ISIS is the way to go. . . and this is the best ISIS bottom bracket made. . . Until FSA comes out with a TI version. This should be soon.

Strength:

Well made, include instructions well written and easy to understand.

Weakness:

The special tool required to fit an ISIS XS BB is not included with the BB. This fact is not advertised in any ISIS ads I've seen. The retailer was not aware of this and every bike shop I visited or phoned in Brisbane had no idea. Now you all know.

Now you know about this special ISIS BB tool you can ask your retailer for it when you buy your BB and cranks (I guess).
The product will probably get 5 chilli's, the company can take 1 and do what ever with it.
They then have the hide to charge me for this $10 socket.

Strength:

Specs sounds nice, four bearings ooooohhhh

Weakness:

Just more bearings to ruin

Rode these for 500 miles on flat ground, never saw rain or mud puddles, got grit in 'em, probably from hosing bike off for regular cleanings. Lesson - avoid direct blasts from hoses around crank spindle. Bearings can be removed from axle fairly easily. I repacked all the bearings, will try it again. My cheap old shimano bb never got gritty in four years of similar use. I think RF has compromised bearing protection on this bb by making it "servicable". They ought to include spare bearings at that high a price.

Strength:

Light weight

Weakness:

It broke !!!!

Well, the BB felt great when it worked. Unfortunately, on a simple Redwood ride (xc fireroad) I felt stiction on certain parts of my pedal stroke. By the time I got back to the car, it was even flexing.

Took the BB out of the bike, and foudn that one of hte sealed bearings were crushed somehow (not sure how) and the axel was a little bent.

Great BB for weight, not sure about durability !

Strength:

-Really smooth
-Great warranty
-ISIS works great

Weakness:

Price, I think the regular price of $124 (Cdn funds) is a bit steep for a BB.

I'm using these with Truvativ Stylo Team cranks and I haven't had to tighten them yet, as a result of this BB the cranks really are much more stiffer than the standard tapered design. 4 chillies for value b/c of the price but 5 chillies overall b/c of the preformance you get out of them.

Strength:

Works great. Smooth bearings. Servicable.

Weakness:

Had to torque like hell to get RF turbine cranks on.

Great BB. A bit pricey but I hope it makes up for the price in the long run. It seems that the ISIS standard change a bit in the early days so I had big problems with FSA. I do not know why it was necessary to torque the crank screw so hard with this one. Will post update review in 6 months.
