I picked up a new set up of Trail 245s last year and put them on my Hightower. I shortly started noticing a strange creaking noise, mostly while pedaling seated. I thought maybe it was my axle , cassette, bottom bracket, rear linkage... could not pin it down. I threw my stock 27.5s back on and the noise went away. I kind of forgot about it until i put the new i9s back on (now with ~100miles of light trail use) and quickly noticed the noise again. Visually, everything seems fine, all the spokes seem to have the appropriate tension. I tried to get a video to demonstrate the noise. I'm hoping an expert here can chime and help identify the creak. TIA
