Shimano Dyno-hubs in factory machine assembled wheels are cheap , less than the total cost of the parts at retail .

check the suppliers to your local bike shop. the shop will hand check the wheel before handing it to you ,in Person,

maybe even swap the tire and offer trade in for your old wheel to go in their future repairs..

Im happy having the light right there .. on, as soon I ride.. No matter what the weather ..

wet tires and sidewall dynamos slip .. as the magnetic resistance is greater than the grip of the roller on the wet tire.

but maybe it rains there even more rarely Than Riyadh .
