It's time to change my stock Crankset and BB on my Enduro 05 Comp 130. Are this compatible on my Enduro?

Crankset:
SHIMANO XT® M752 CRANKSET
Silver, 175mm, 22/32/44T

Bottom B:
RACE FACE EVOLVE XC BOTTOM BRACKET
113mm, 68/73mm, M15 Bolt

Thanks!

You'd need a different bottom bracket for those cranks or different cranks for the Race Face bottom bracket.

Ok. Thanks for the info.

Any suggestion for a good "light" Bottom Bracket for the SHIMANO XT® M752 CRANKSET?

The 05 Enduro 130 requires a....

68x118 bottom bracket. In 05 Specialized changed the bb width to maintain a 50mm chain line. If you get a 113mm your cranks will be to close to the chain stays and your chain line and thus your shifting will be off.

Any idea whether or not these are compatible with a 2002 Enduro?

Truvativ Holzfeller Crankset 22/32/44
Drive: ISIS Splined
Ring Size: 22/32/44T
Speed: 9
Arm Length: 175mm

Truvativ Giga Pipe SLLT Bottom Bracket
Drive: ISIS Splined
Spindle: 113mm
Shell: 68mm

The Bottom Bracket shell width is 68 mm. Any other problems to make note of?

Yes that should work just fine...

the 02 Enduros used a 113mm spindle. Spec didn't change them to 118 until 04. The silly thing is there was some trasition time in there and it was conffusing. From 02 on back to whenever the EX 30 or 50 in 68X113 was standard. Then in 04 for the Enduro they went with an ES 30 in 68X121 until you got to the Pro model which used the intergrated 2 piece crank sets from there on up the line. Then for 05 things got even more confusing. The SX models took a 73x118, and the Enduro (all other models) used a 68x118 up to the Pro and above which again came with the intergrated bb crankset. For 06 EVERYTHING in the Enduro line comes with an intergrated bb crank set and Spec has gone to a 73mm bb shell on all models. All the foregoing was just for informational purposes. Conffusiing aint it? :D

The set up that you have listed should work just fine for your 02. Things were simpler back then!

Is there another brand/company that makes 68x118 BB aside from SHIMANO® ES-71 BOTTOM BRACKET?

Also, I'm planning to buy a spare tire 26 x 2.7 for Downhill. Will this fit on my Eduro 05 Comp 130 stock fork?

Thread Hijack - Sorry

Sorry to hijack your thread judd but I'm having problems with my newly built 05 S-works enduro bottom bracket and I didnt want to start a similar thread.

I dont know what width the bottom bracket should be. By that I mean I have an X-type bottom bracket fitted but my heels keep bashing against the seatstay. Can anyone tell me the correct width please?

Does anyone else have this problem? I ride toes-out but it's never been a problem on any other bike except the spesh. Thats whats making me think I need some spacers on my bottom bracket.

BTW - The b/b was taken off another bike and it was all built my me, my first time, so I'm expecting it all to be my fault.

Thanks everyone.

If you are using the stock crank set, you are stuck with the shimano bottom bracket. Specialized uses a shimano type spline interface for their 3 piece crank sets. To my knowledge nobody else makes a splined bottom bracket that is compatable with the shimano interface.

Are you hitting just one side with your heel or....

both. If you are hitting both then there isn't much you can do about it. It isn't the spacing of your cranks but the position of your feet. If you are only hitting one side then a spacer or two might solve the problem, BUT!, and this is a BIG but, adding or subtracting spacers, or moving then from one side to the other will affect your chain line. Chain line is critical for proper shifting both front and rear. Chain line is the relationship between the center cog on the cassette and the middle chain ring of the crank. Chain line is the line that can be drawn between these two, and that line needs to be as straight as possible in relation to the frame. The usual reference point on the frame for determining chanin line is the seat tube. The Enduro needs or uses a 50mm chain line. That is the middle ring of the crank needs to be 50mm from the seat tube in order to achieve proper alignment with the cassette for optimum shifting performance. You can fudge the chain line about 1mm one way or the other, a 49 or 51mm line will work. But much over that and shifting will start to suffer.

Like I said if you are hitting both sides then it's your foot position. Enduro frames, rear included, are beefy and use large tubes for strength, and some pretty wide spacing between the stays to accomdate wider tires. I had an 03 Enduro and currently ride a 05 Stumpjumper. I ride with my feet straight fore and aft. It dosen't take too much heel-in movement before I tap the chain stay on either side with my heel, and it took even less on my old enduro. I can see where it would create a problem for a "toes out" riding position.

Anyway. bottom line is the correct width for an old style 3 piece crank for the 05 Enduro is 68x118mm, this produces the correct 50mm chain line. For the X-type or the Shimano 2 piece bb (you are using the X type) the correct chain line is achieved through the use of spacers according to the manufacturers instructions. Check you chain line for the front by measuring from the center of the seat post to the middle chain ring. If it's 50mm you installed it right to begin with. If not then adjust it accordingly. But it sounds to me like you have it right to begin with as you are not complaining of shifting problems. If you can't adjust it out, you may have to live with it or suffer poor shifting performance.
