The GMC Yukon features a strong aluminum frame utilizinga floating beam suspension design, mated to a Zoom suspension fork with elastomer/spring technology. The Yukons drivetrain starts with Microshift twist shifters controlling Shimano’s tried and true TZ-30GS derailleur, and finishes up with a strong aluminum wheelset featuring a V-shape rim profile and high flange alloy hubs. Stopping is handled by Promax alloy V-brake front and rear, vastly superior to rim brakes especially under adverse road conditions. True to it’s GMC roots, this bicycle is rugged, good looking, and built for the long haul. Frame Size Top Tube Chain Stay Standover Height 19″= 48.0cm 56.0cm 43.0cm 31.0″= 78cm
Micro Wave Oven, Mens 26″ Mountain Bike. These were gifts sent to my daughter-in-law and my grandson. The mountain bike was not even setup and if it was delivered as not being setup, you should have added an extra charge for the bike to be setup at your location.

go easy on it – Hesston L. Johnson – Springfield, Missouri, USA
This bike I have owned for a couple months…it has been on 3 mountain bike trails at around 10 miles each, all rough; and many miles on city streets, city trails, and country roads…
I bought this bike because I was interested in mountain biking and did not want to buy a total piece o’ dookie to ride on from Wal-Mart or something (aside from being an anti-Wal-Mart person) and got this…
Turns out, I really enjoy mountain biking. The bike held up well on streets, country roads and EASY-PEESY trails…if you are jumping roots, logs, going through mudd (especially mud), creek beds, water, etc, this is not the bike for you…The rear derailluers slip easy and the bike does not change gears very well. At this time I can only use gears: 1, 2, 4, 6, 8, 9, 11, and 13 out of 21. The entire 3rd gear set does not work because the front derailluer is crap. I spent 2 hours working on it the other day and had a bike guy look at it, it’s fubar. I was not aware of this until riding through town with a “speedy” biker. The guy has a Trek street bike, so we got up to about 20 mph quickly. When I tried to go into gear 15 through 21, SNAP! and I almost fell off because the bike locked up from being able to change those gears…
The seat is very uncomfortable. The bike is fairly light, which is good for trails when you have to carry in and out your lunch and water… The front shocks work well…
I finally snapped and decided to get a different bike and bought a Trek yesterday…looking forward to it getting here. Took this on a trail today, other than the caked on mud, slipping gears (from all the mud) and still missing several gears, it does what it needs to do.
Happy Trailing!
