The stopping power should be strong enough because of the very big diameter of the disc, the problem will be the weight and the disc should be well protected from deformation.

more weight on the more diameter of the disk.

you should consider to change the V-brake for your front brake, its really powerful and cheaper then the disk break!!!

yea i know that it should be more powerful breaking bacause of the bigger diameter. wow you guys english are very good. i wonder what brand it may be, or if its just someone trying some on thier own.

hey question. how to get the vimeo clips on BTT?

It's most likely a genius' prototype since every bike maker knows it is not a practical design.

cool~~~i like it!! XDDDD

but its adapter is soooo big

i think it isn't strong enough =口=
