Purchased this for my 8 yr. old son's bike. This is his first bike with a clutch. The adjustment allowed me to set it up with a short throw for his small hands, also made for a somewhat easier pull for him. The quick adjust is a little weird, can't seem to get it to have the adjustment that I thought it would, I ended up fine tuning it with the lower adjustment at the clutch arm. It's possibly due to adjusting the throw so short, has to do more with me than the assembly. Once the boot is installed you can't see what's going on with the adjustment. Use a little Vaseline to get the adjuster boot on, it's super tight (good thing).
