It's a little loose on my Trek 7.2 FX, but for the price this is a great product for anyone looking for smartphone storage on their bike to easily connect to a bluetooth speaker mounted to the handle bars.

Used this to replace the original Bontrager seat on my Trek mountain bike. This seat seems to have the gel in just the right places and I can ride all day without becoming sore, a vast improvement over the original seat!

I just received these this evening and I can't wait to use them. We just returned from the Galapagos and I had an old set of trekkers that I used to hike 11 of the Colorado Fourteeners which I brought with me.  I left my old trekkers in the Galapagos and ordered these from Amazon.  They fit nicely in a backpack and seem sturdy and easy to use.

Happy Trekking :)

Update:  Ok, I used them and they are G R E A T https://www.amazon.com/Foldable-Sterling-Endurance-Ultralight-Adjustable/dp/B017QKE8D6/ref=sr_1_1?ie=UTF8&qid=1471313870&sr=8-1&keywords=sterling+trekking+poles

Good product. These bars and a high rise stem allow me to assume a more upright position on my Trek 7.2 fx. Much more comfortable.

The contents are perfect for my mountain bike day pack.  Luckily I haven't had to use it yet.

The seller provided me with one of these rearview bicycle mirror for evaluation seeing comments from a few buyers with issues that he did not feel were credible and asked me to test them. The first issue was the fit on the handle bars. I attached the mirror to my Trek road bike handle bars which measured 3/4 inch in diameter, as stated in his listing. The mirror fit just fine after tightening the mounting bolt and did not move in either direction when pushing on it. It was easy to attach following instructions that included ensuring the nut stay fully seated in the bottom of the rubber insert to properly mate with the bolt. The mirror stays rigid and does not vibrate when the bike is moving. The vertical viewing area may be less than desired but bending the mirror to 45 or 90 degrees provides an adequate rear view. The mirror is study and the glass is secured within the rim. The design of the mirror may not be liked by some potential buyers but none should fault it for the issues Ive evaluated it for.

The grips Look and feel great. Easy to install but you need a 3mm Allen key and it was not included in the packaging with my order. My Grips are orange and black with little skulls fit great on my Trek  XCaliber 9 hard tail mountain bike. They are about 1/3 inch longer then the stock Bontrager grip that came with the Trek hard tail mountain bike. So you also may need to move your shifter and brake hand control grips.
So get out and enjoy Mountain Biking. ABL from Miami Fl.

My Trek bike would not fit on my CycleOps trainer.  I got this skewer and it works like a charm.  I'm riding my Trek during winter on my CycleOps and while watching cycling youtube training videos on my laptop.  I even use the Wahoo TICKR and my iPhone 5s to track my heart rate and calories burned.

As this frame bag is not available in Germany, I ordered one in the US. Delivery was perfect by Amazon.
The frame bag fits perfectly into the frame triangle of my Trek MTB. Unlike other bag, this one is big enough
to carry an accumulator for my self-made e-bike. The material is strong enough to hold the weight of the battery.
At the reasonable price, this bag is really highly recommended.

Great price, easy install. Beats the stock grips I received with my expensive Trek cycle. Will by for my future bikes.
