It's gonna work, cause it's 'Made in Germany', not in china or some place around. Gearboxes are the future, it only needs to drop the price and find trust from the bikes manufacturers. The cassete/derraileurs system has been around for decades, it's time to get some better stuff....

I hope this one don't scratch the rear tire on the seat tube, like the old one. Really nice bike.kudos to transition, getting an already good one better.
