For full geometry, see photos. Approx 17.5 centre of BB to top of seat mast. I’m 6’0. Fits me really well. Really smart and special! For 27.5/650b wheels. Post mount disc brake (160mm native). Tapered head tube- original headset included, in good working order. Fits 31.6mm seat post, semi-internal cable routing external on down tube, then goes inside the seat tube. Neat but very easy to do a cable change. 140mm – 160mm front suspension. Super short chainstays for a playful ride. Aggressive hardcore hardtail with 64.1 degrees static HA (160mm fork). 27.5? X 2.8? Tyre clearance. Boosted Bird chainstay yoke that runs boost or non boost cranks depending on chainring size (30t or below will run non boost). One piece machined brake mount and dropout assembly for maximum precision and minimum squeal. ISCG05 chain guide mount. External cable routing for easy maintenance. Continuous outer gear cables for maximum cable longevity. BSA threaded 73mm bottom bracket. Stealth dropper seatpost routing. All really well made and designed and in good condition. I bought this in the 2020 lock down and haven’t ridden it nearly as much as I anticipated. Please study the photos carefully as they make up part of the description. Feel free to ask any questions??
