Hey Guys, new to the forum. Been on my Relay since August of 2023. Flew to Bellingham, picked it up and rode 5 days in the PNW and one day at Whistler MTB park. Been a sick bike, but like all my bikes, never without some glitches here and there.
TLDR:
When you pull the motor to grease the motor mounts, use Copper Anti-sieze instead of grease for longer intervals between re-greasing.
Regarding the creaking in the BB area. That's typically going to be the motor mounts. August 2023 in the PNW was painfully dry and PNW dust is super fine, pretty much just like Utah dust, just a little darker. The creak developed after about 2 months. Granted, two-a-day rides for 6 days in the PNW is more riding than I do in 2 months at home. But that fine dust made its way into the grease and thus the creaking began. I pulled the motor, lightly greased the threaded aluminum plugs, reinstalled the motor, got back to riding. Unfortunately, it was super dry at home as well and the creaking came back after about 3 weeks. Did it again just before a MTB trip to Peru but used more grease. Rode 8 days and about 83,000' of descending in Peru. Got back home and rode for about a month before the slightest hint of a BB creak started. As soon as it did, I pulled the bike apart for an overhaul, it was due. This time, I used copper anti-seize instead of grease on the motor mounts. That was early Jan. I've been riding at home regularly and have taken 2 trips to ride out of state since then. No creaking yet. ~Fingers crossed~
