PSM is an independent shop in Lakewood, WA. I've taken my wee to them several times for tire mounting, electrical work, and some repairs. Last year I had them install a new chain and sprockets that I bought from SV Racing. Everything was fine for a few thousand miles, but then I started having trouble keeping the chain adjusted and found the master link wasn't properly sitting on the sprockets. The owner, Steve, checked it out and admitted his tech hadn't done a good job on the install. He ordered a new chain (the sprockets checked out okay) and installed it. No charge, no haggling, not even a mention of proration (the chain had over 6k miles on it by then). The experience was consistent with my past dealings with PSM. The work is done when they say it will be and the charges are always less than I expect. An excellent shop run by a stand-up guy.
