Erik B.wrote a review of Yeti Cycles SB100 GX Eagle Comp Complete Mountain Bike on July 20, 2018
Familiarity: I've used it once or twice and have initial impressions
I was stoked that Competitive had this bike available for demo. Their demo experience was spot on. They have a bunch of high-end bikes to demo. I took the bike up to Snowbird. I rode to the top of hidden peak and rode the Big Mountain trail down. I was a good test of the bikes capabilities.
Climbing: This was my biggest gripe about the bike. The bike felt supper light on the front end. It made climbing pretty squirrely. The front end would just wonder while climbing. I think part of this is the head tube height on the bike combined with race face bars. You might be able to remedy some of this with some lower rise bars but you shouldn't need to buy anything on a 6k bike. Another issue I noticed while climbing was my heal was constantly contacting the rear triangle on the drive side. I've never had this issue on my SB6 running the same XTR pedals.. I'm not sure if the Q factor on the cranks was smaller or what but again this bike/frame needs to be perfect in this price range. The eagle gearing was great for climbing no complaints there.
Descending: This is where this bike shined. The geo felt way more at home flying downhill than up. I love the way the way switch infinity bikes feel in their rear suspension. It feels bottomless. It lets you brake latter into turns. The front fork didn't feel as good as my Fox 36 with the Fit4 but I might have had a tad too much pressure in it. It ate up snowbirds big mountain trail with no problems. Very playful in the air for a 29er.
The Build: I weighed this bike at home. It was tipping 29 lbs with xrt trail pedals (size medium). Again this is porky for a bike labeled as an xc bike. Hell my SB6 is probably only half a pound heavier. I'm sure you could swap out a bunch of stuff and get the weight down but again 6k. I like that they spec'ed it with xt brakes. They were solid. I hate the WTB seat they have on this and it's heavy. The bars and stem are nothing special. I'm a sucker for fox suspension and I wish I had more time to dial in the fork to see how it performed.
All and all I wanted to love this bike but I think I will keep searching for perfect Wasatch Front ripper.
