Can I assemble Efneo Gearbox to my bike myself?Yes, if you have the basic tools and skills. However, we think most people would prefer going to the closest bike shop to have it done.
For what type of bikes is Efneo Gearbox dedicated?For any type of bike that uses a tapered squared bottom bracket, excluding off-road bikes (mtb, trial, bmx, etc) and “fixies”.
Does it work properly with a rear derailleur?Yes! It works very well with a rear derailleur. And the main benefit is you can forget chain-skewing!
Does it work properly with a rear hub gearbox (e.g. Shimano Alfine)?Generally yes, but to be 100% sure please check the specification of your hub – some manufacturers specify that the chainring in the front should be at least 30-34T. Efneo uses 28T. This condition does not apply to bikes with wheels 20″ or smaller.
Will it fit my derailleur shifter?No. The gearbox is delivered with the shifter.
When will you start production and pre-sold items delivery?We assume no later than Autust 2015. However, we’re working on making it sooner!
The Efneo products are still in development, so please, be aware, that technical specifications are subject to change at any time, without prior notice.
