Starting this thread for Transition triple owners and those who have experience with them. They have been out for a while and have stopped being made, but there it's a lack of info on them.
I just picked up a used frame and will be building it soon. But it does look like I need to put new bearings in the main pivot. These look to be 6808 RS bearings.
I found mine on this site, new in box, in January. I love it so far. Added new wheel set, cassette and derailleur. My first mtb, I chose it because of my BMX background. I am learning so any info would be great. Good luck on your build !!!
