Question: Will this fit a Trek Shift 3?
Document: I would definitely not recommend this unless you like really heavy kickstands (3 times the weight of their old ATB design) and you are a glutton for punishment tracking down screws that fit. All four screws are 3'/4" too short for my Trek and are also Philips head, which is nonsense on a modern bike, since nearly everything is hex recess drive now. I am currently looking for a better engineered kick for my bike.
Fortunately, this product fit my Trek 8.2 DS but I can see how the design on certain bikes might keep this from fitting correctly. It fits snugly on the back of the bike and works great.
Instructions would be nice...but this is actually pretty easy to install. I just looked at the pic online and it was obvious how it was supposed to go. The only problem is, it doesn't quite fit my '09 Trek Women's Hybrid 7200. I have it on there now minus one screw...which makes it not quite as secure as it should be.
This is a great product, a must have for anyone who is considering panniers or just hates leaning your bike on any available object to keep it clean and avoid scratches. This stand mounts in less than five minutes and works perfectly with no damage to the frame or paint. Mounted on a 24" Trek 620 (1984) it required no trimming or adjustment, fit perfectly out of the sack.JG
My Trek mountain bike came without a kickstand. I purchased an aftermarket one at the bike shop but returned it as it got in the way of the pedals and never really fit right. The Greenfield fits behind the pedals and doesn't get in the way. It's rock solid and holds up while biking the trails without bouncing around. It also holds the bike stable when deployed. It does ad some weight but no more than other kickstands. Easy to use and install.
Kickstand took 3 times longer to install than the disc brake compatible model made by a different manufacturer but sold by the same vendor. Screws were small and stripped more easily than the higher quality ones with the other model, which was a little less than twice as expensive. After securing the kickstand in place on my son's 20" mountain bike, I sat on the bike and leaned on the kickstand to make sure it was secure.
Works great with my Topeak Explorer Rack, and Topeak MDX Bag with zip out and and unfold paniers. I have carried up t 40 lbs. of groceries and have had no problem with the bike tipping over while on this stand. Great product and very sturdy. I'm so glad that I have done away with the other forward mounted side kick stand. Very competitively priced and there is no extra need to spend another $3.00 for the rubber foot that is normally charged by Greenfield for its other kickstands.
Works great on my Trek 520 and was easy to install. I will have to put some more miles on it to see how the screws hold up
Excellent product. Sturdy and well built. Bolted to my trek 930 perfectly and without needing any shortening. Would highly recommend it.
Works great for my Trek DS 8.1. Makes the bike steady even with full panniers. I'm not a fan of the no kickstand bikes.
Answer: yes
