|   S-works crank VS. XTR crank: big difference? | choopa
May 28, 2002 7:37 PM | | weight wise, what combo crankset/bb is lighter? 99 S-works cranks or XTR? Thanks |
| weigh is the same: 685g but... | nino
May 28, 2002 11:06 PM | | ..the XTR is MUCH stiffer than the S-Works crankset and the chainrings shift A LOT better and ar far more durable.am I right that `99 s-works still was for square tapered BBs?If i remember right the `00 was the year they started with the splined pattern.if you happen to have the square spindled version then you have at least the advantage to get a ultralight BottomBracket like Titec or FRM (both around 140-150g).XTR splined weigh 185g for older,serviceable versions and up to 215g for the actual `02 version.
another weight saver on your s-works cranks are some Aluminium chainring bolts.they will save about 30g over the standard steel ones.
cheapest and lightest option:
get new Sugino supershifter rings,some Al chainring bolts and a lightweight Ti BB.that will save about 100g over XTR.but then stiffness is still weaker than XTR... |

May 29, 2002 2:13 PM | | I just went to light-bikes.com and saw your bike. Very nice. I own a 99 specialized s-works FSR and as of now it's pretty hefty at 25.6lbs. The cranks must be 00' I gues b/c it's on XTR splined bb's. Thanks for the help |
