I’m about to get my hands on a Quarq Elsa10R GXP Powermeter Crankset, but I want to make sure it will fit on my Planet X bike. It has a BSA threaded (Full spec: http://www.planetx.co.uk/...sram-time-trial-bike) bottom bracket. Is it possible to - with this information - tell if it will definately fit?
Also, Wiggle for example has “Quarq Elsa10R **GXP **Powermeter Crankset” and a “Quarq Elsa10R **BB30 **Powermeter Crankset” for sale, does it matter which one I get or will they both fit?
The Quarq website says the Elsa 10R (not telling if it’s GXP or BB30) will fit a BSA/English threaded bottom bracket so I does sound like it would.
BB30 could fit through various adapters/differing bottom brackets, but I wouldn’t reccommend it.
No. A BB30 Quarq will not fit BSA frames as there’s no room for the bearings (there is one BB30 crank that I’m aware of that will fit BSA frames with the appropriate adapter, and that’s the Rotor 3D+). BB30 cranks are the most restrictive in terms of frame choice; BB30 frames are the least restrictive in terms of crank choice.
The new elsa cranks have a long enough spindle to work with this bottom bracket. You simply do not use the pre load adjuster or the 11 mm spacer on the drive side.

This is not correct. I have a BB30 Quarq/SRAM S975 crank on the BSA bike with a Rotor BSA30 BB. The Quarq (and SRAM S975 S950 or S900) and Rotor 3D+ have a BB spindle length of long enough to run on a BSA bike. However those are the exception to the BB30 standard and other BB30 cranks do not work with BSA bottom bracket due to the spindle length.
Too many threads like this on a lot of boards. Hopefully manufacturers will realize they are screwing themselves and us with all the competing standards.

Or maybe this is an example of why you become good friends with your LBS and give them the business, or at a chance at earning your business.
