NOB Universal computer mount- 20mm NOB, 36mm strap clamping diameter

Bought to use on a TerraTrike Rover i8, mounted to the left Versa Bar, to hold a Planet Bike Protege 9.0 cycle computer. Bought two just in case, although only one is in use for a cycle computer.Do wished there was a 1/2 inch longer version so can use with a Bontrager Flair R rear light attached to a TerraTrike Headrest. That would give me an optimal position to mount a rear light too. And, wished this company sold the 30mm version so I could could probably use with a Bontrager ION 800 R front light.Can probably cut some PVC pipe in half to go around this mount, then add zip ties or glue to hold the PVC flanges on with, then attach the Bontrager lights to. Not gotten around to trying it.

This was useless for me. It is not 20mm as stated but is instead over 25mm. Be sure your accessory can be mounted on a 25mm mount.

I put some aerobars on my bike for triathlons and I could barely get my computer to fit inside the aerobars. I wanted to move the aerobars closer in to be more aerodynamic so I picked this up. It fits snug, holds the computer nicely, and only slides if you push hard on the computer. So it isn't a vice-like grip as it is all plasctic, but its inexpensive and works quite well.When I first unpacked it, it seemed kind of small, but it works well for my computer, which is a small 2-button, watch-sized, Specialized Turbo. I seriously doubt that one of those monsterous, I-pod sized computers would have enough room to mount.

Ah, this is not the best you can buy, is very good and functional. I use them on the fork to attach a head lamp LOW, NEAR the pavement.

fit perfectly, easy to install.

Works Great
