BB options for IP-036
« on: August 09, 2014, 02:54:37 AM »
On my IP-036 build, I'd like to use my current SRAM XX crankset (GXP).  I installed Praxis' conversion BB, only to find that my frame has a 68mm BB (opposed to the 73mm MTB "standard").  I highly recommend Praxis, this was the fault of my ignorance.

Lesson now learned, what can I do for a BB?  I'd like to use my current cranks.  I use a single chainring (1x) setup.  And though I'd love to convert to 1x11 the whole goal of using parts from my previous rig, and even buying chinercarbon, is to keep costs low...

What do you guys use on your builds?

Sorry, I am unable to be of much help.  Both my Chiners have BSA BB and SRAM XX1 GXP cranks.

Just to be sure Arrjay - the shaft on your crank is to long?

The shaft on my current crank is the correct size.  My previous BB was BSA with 68mm shell width (Niner did this for a couple years on the Air9).  So my issue is finding a solution that can convert PF30 at 68mm shell width that can accommodate a GXP spindle.

Problem Solvers may have . . . err, solved my problem:

Update:

Ordered the Problem Solvers A46 (CR0095 for SRAM/GXP, CR0094 for Shimano) and successfully installed this weekend. 

So now I'm running my "old" (thank you manufactured obsolescence) SRAM XX GXP crankset on my PF30 68mm shell width frame!  Success!

The exploded-view on the install instructions was slightly cryptic and required pressing the GXP-specific (provided) adapter into the Non-Drive side, then pressing in each side of the BB, but things are looking good now.  I even had an email exchange with Problem Solvers support to confirm I did things correctly.

If anyone has some questions about this feel free to PM me, or PS customer support directly.
