Review: solution to lack of attachment points on trek 7100 multitrack - This was the exact adapter we needed to attach a rear rack on a trek hybrid 7100 multitrack (2004 model). I will upload a photo to show our set-up. The bike itself doesn't have the typical attach points, and for years, I just used a backpack to haul. But now that my tween is using my bike as a daily commuter to his school, we needed a solution for. Happy to report that this was an exact fit for our seatpost. In order to figure out the correct size, I used a flexible tape measure (like a tailor would use) and measured the circumference. (you could also do this with a narrow strip of paper and then just use a regular ruler to measure the length.) Then some math to solve for the diameter: C=2 * pi * r ==> Diameter = circumference divided by pi (3.14). Then if you need to convert inches to millimeters, multiply inches by 2.54 to get your cm, then move that decimal and voila! (There's online calculators to do all of this for you, too.) This is solid and well made piece. It was easy to install and the hardware that came with his rack threaded in perfectly.

### ⭐⭐⭐⭐⭐ a must have for mounting a rear bike rack.
*by R***R on April 3, 2026*

very well made,fit like a glove & fixed the carrier issue easily.

### ⭐⭐⭐⭐ Great with a small caveat
*by I***S on February 14, 2021*

I love this product! It has allowed me to lower the seat on my ebike by about six inches. This is great! Now I can sit on my ebike without feeling like I’m going to fall over, all while retaining my rear basket and removing it’s ridiculous mounting point to my seat post. If I love this product then why only four stars? The mounting holes for the rear basket are far too close. They should be spaced about and inch or two further apart. Yes, they may require a bit more material to build them this way, but in doing so they can alleviate the stress that is placed on the hardware of your rear bracket/basket. Otherwise, it works as intended, and is a good alternate choose to seat post mounting.
