What is SRAM GXP crankset?
Sram GXP is a very popular crankset standard used by SRAM. It offers an industrial based bearing arrangement and was touted as having the lowest weight and rolling resistance of any crankset bottom bracket standard.
Is SRAM GXP any good?
The Team GXP bottom bracket with steel bearings is a good value. Installation is a cinch and so far the BB has held up well. I had it on my last bike for well over a year and the bearings were still spinning freely when I sold the bike. This is for 68 or 73mm BSA shells and SRAM GXP cranksets.
Is dub the same as GXP?
What are the main differences between DUB and GXP? DUB uses an oversized aluminum spindle, while GXP uses a 24mm steel spindle. DUB cranks fit into all major existing frame BB shell standards while GXP only fits into the 24mm specific versions. DUB BBs are also more durable than GXP BBs.
Will GXP fit BB86?
Yes, the PressFit GXP is the bottom bracket for use with Sram GXP cranks in BB86 frames.
How does the SRAM GXP crankset split work?
The crankset split is on the non drive side and uses a tapered fit (this is problematic, see further on) The non drive side crank arm attaches to the axle using a very shallow taper. GXP was one of the few crank standards that used a stepped shaft and subsequently a fixed/floating bearing arrangement.
Why are SRAM GXP frames compatible with Hollowtech 2?
From an engineering perspective it is obvious that GXP was designed to skirt around Shimano patents related to Hollowtech 2 whilst maintaining close compatibility to frames. It appears to have been designed so a modification (additional spacer) to a Shimano bottom bracket could be made to allow it to make it GXP compatible.
Which is SRAM crankset has the lowest rolling resistance?
Sram GXP is a very popular crankset standard used by SRAM. It offers an industrial based bearing arrangement and was touted as having the lowest weight and rolling resistance of any crankset bottom bracket standard. The engineering will be analysed in detail.
What kind of axle is a SRAM GXP?
GXP axles are steel The section towards the drive end is 24mm The section towards the non drive crank arm is 22mm (stepped) The crankset split is on the non drive side and uses a tapered fit (this is problematic, see further on)
