I'm new here on the forum Allow me to quickly introduce myself..
I'm a Belgian XC rider that has 2 Niners. (Jet 9 RDO + Air9 RDO)
However on my AIR9 I have a fair amount of issues with my BOR Crank XC666. My LBS is also in the dark and proposes to use a Sram XO crank. (using GPX) Not really fond of replacing this (expensive) crank already. I was wondering if someone here could help? I'm not a techie so I'll try to explain the best I can..
After some time my crank gets a bit pushed out of the PF30 BB. This results in shifting problems on my rear cog. (shift onto my 36 cog). I'll have to go to my LBS to get this fixed. (sometimes twice a month!) Also when I ride in rainy conditions, dirt is coming very quickly between the seals. Very annoying to listen to a "sandy crank" Extensive cleaning doesn't help.
Anyone who could help me out? If more info is needed, let me know.
I'll post some pics of my rides later on in the RDO thread
Crank: BOR 666XC-29er - 2X - Smart Spindle System | B.O.R - Germany
PS: I already looked into the "pf30 experiance dbb" thread but have not found a solution yet..
