Left-Side Drive

Sheldon with left-side drive bike

Do you remember when a “10-speed” bicycle actually had 10 speeds?

Are You Dish-Gusted with potato-chipped rear wheels?

Now we're up to 10 sprockets at the rear wheel alone, and counting...

Of course, that's great – more is better! But having all the sprockets on the same side of the wheel is silly in the extreme! If present trends continue, before long the right-side spokes will have to lean to the left, or else cyclists will lose their balance reaching for the right pedal! Either of these developments would put an end to cycling as we know it!

To the rescue: the ShelBroCo 5 and 5 system.


Our revered founder, Sheldon Brown, (photo at left) proved the feasibility of a chain on the left side with his prototype system (see detail at right). Now we take his innovation to the ultimate level. With five sprockets on each side, the ShelBroCo 5-and-5 System gives you all the advantages of the classic ten-speed that you know and love, and of a modern ten-sprocket system, and much, much more.

ShelBroCo 5 and 5 system

Spoke Divider

It's not (only) about the Dish! Enjoy a nice, tight Q-factor for carefree cornering! No more clumsy, time-wasting double shifts! Chain angle is never a problem especially when used with S-Broco Hi-Gain Cranckx™. Drive efficiency increases by more than 15%!**

ShelBroCo DoubleCross™ spoking stabilizes your wheel against rotational and lateral torque! The 5 and 5 system is a perfect complement to ShelBroCo Symmetrispokes, because, at last, the rear wheel is truly symmetrical!

The ShelBroCo 5 and 5 system is available in configurations to match the needs of any cyclist!
