my weakness is you

[Dec 02, 2019]


July 1, 2019: I bought frame only and built it with the parts I already have. The frame weighs in at 6.06 lbs and that's with seat clamps, dropper post cable brackets and bolts, RD hanger and thru-axle. I think that's pretty good weight although GG website says 5.8 lbs for size S1. Frame is very compliant going over chattery stuff. You can pick up speed without holding back. The bike can take it without getting tossed around. The frame has a unique feel to it that sometimes you would think you have a rear suspension until you hit a bigger square edge roots/rocks and you'll be quickly reminded that you're on a hardtail. The bike is also very agile, quick in transition and likes to boost off of stuff. Very easy to pop a manual or hop over stuff without over working yourself. Steep STA that makes climbing very efficient. The position above the BB is so natural with every power stroke to the cranks gets transferred to the wheels without wasted energy, and in papers, the STA is only 74 degrees but it feels steeper than my 75 degree '19 Marin SQ2 even though I have 542mm a2c. Obviously, technical climbing requires a lot of body fore-aft movement but I'm still able to do without too much drama. Don't get me wrong, the frontend feels light and it will wander but a quick weight shift fix this as long as you have gas in the tank. ;) My complete build weighs in at 28.5 lbs and this is with Vittoria Airliner insert in the rear, Baron/Hydra wheelset, Pike 150 27.5, PNW Cascade 125 dropper post, 780 Nukeproor Carbon Horizon 38mm rise, 35mm stem 2.8 Butcher and Rocket Ron. I'd recommend to anyone looking for a compliant aggressive hardtail but really look into their reach and max dropper post travel.


Updated on Dec 2, 2019 (600 miles) Short chainstays that the wheel is literally under your seat so when you hit a bump while pedaling, you will really feel that hit. This is only noticeable when going fast on flat section of the trails that has bumps. Obviously, when descending, I'm off the saddle so that doesn't matter because off the saddle, this bike is very compliant. Even though the seat tube is 419mm long, the max seat post insertion is only 190mm. My inseam is 30.6" and I can barely use a 125mm dropper post. Meanwhile, all of my bikes even my previous Marin San Quentin 2019 can fit 160mm and my 2019 Stumpjumper can fit a 170mm. That is big difference and there's complain about this in the forums. The reach is short for S1 and if I opted for S2, I would probably only have 80mm of travel in my dropper post. I have 52mm chainline (boost) and for some reason, the gap between the chainstay and chain ring is only 1mm with the 30T and with the 32T, the gap is like .5mm. No clearance at all! If I put a spacer in the driveside BB, it throws off the shifting to my 42T 11 speed XX1. This frame is so expensive yet has no value. I paid $1280 shipped and I can't even find a buyer to pick it up for $800. smh
