Question: Would this work on a Trek 820 mountain bike? Thanks!
Document: I changed out the rear axle on a used Trek 4300 that I just bought. It was a fairly low end mountain bike, hence it had a solid rear axle. I hate that, because if I get a flat I want to be able to fix it immediately. These work nice, they look nice, and they were cheap... Can't ask for any more than that.
Someone stole my rear skewer and left the wheel attached to bicycle. Why? I don't know, but I needed a replacement. This was the least expensive one I saw on Amazon.It's a good looking skewer, with a gun metal gray (not shiny chrome) end pieces. It fits perfectly on a Trek mountain bike.Look at the photo carefully: see the cam where the quick release lever rotates?
Works for me! I just needed it to replace my good skewer while I have my bike on the trainer. Didn't care about aesthetics or weight. I would recommend this product for that purpose.
This product came quickly and was as advertised. I will definitely use them again when ordering for my mountain bike.
I lost the tip when replacing a rim for a mountain bike and this reasonably priced part pretty much fits the bill.So turn your bike upside down, move to lower gears (gain more chain space), and do your thing.When installing the quick release make sure that the lever is pointing to the back away from the pedalsand it has to leave a mark on your hand... which means pretty tight and enjoy riding.
Only owned it 1 day but so far so good. Actually I like it better than the original Trek (shimano hub/bontrager wheel) skewer. However my trek is in the $500 range so nothing fancy to begin with. Lever arm is easy to adjust and snug down.
The front skewer that came with my 2011 Hardrock stripped its thread so I ordered this one as a replacement. I decided to order the rear one too to have as a spare. I was not expecting much of them other than to do stop the wheel from falling off until I got a hold of the original skewers. I got more than I expected. The skewers are very nicely finished in their matte metallic paint and they work just as well as the "better quality" skewers on my specialized camber.
I like the appearance of this design more and think it makes the release easier to operate.Five stars because this is a unique, good looking, and functional design; the fit for mountain bikes is perfect; and the price is low.PS The hanger card says this fits 6-8 speed wheels, not just 7-8.
Been using this on my bike for a over a rear and have no problems. Works well and it seems to be better quality than the original.
At first I thought this skewer is not long enough. But actually, it fits my bike very well. My bike is Diamondback Sorrento.
Answer: yes
