Carl Strong custom built titanium 27.5" mountain bike frame (M). If you don't know Carl, he's been a builder for about 30yrs and builds around 100 bikes/year in Bozeman. I don't think anyone is more respected in titanium, here's a link to his site: https://www.strongframes.com. This frame is built around a 140mm fork with gorgeous shaped tubes, 27.2 seat tube, incredible welds and a Syntace 148/12mm rear end with hard mount derailleur. It's a solid medium with a sweet spot of 5'7-5'9. I have pictures shown of it built up on 2.8" tires to help further with the size/fit (sorry I don't have geometry sheet). I'm the second owner. It's been meticulously cared for/handled and the drive side chain stay was always wrapped. It has been ridden though and has some cable rub on the top tube (really covered by cables) and a slight polish spot on non-drive side chain stay from a flat. You get everything shown including the King headset, Ritchey post and the vintage titanium Blackburn cage. The frame alone from Carl today is $3800 and many months to get. If you want the best, this is it. Frame is for sale locally in all the usual places and I reserve the right to end listing anytime. Local pick-up is great. I would carefully pack and ship anywhere in the 48 for $100 flat.
