BREYDON’s wheelchair trials: GRIT

Global Research Innovation and Technology (GRIT) is the retuning of the dream to appeal to the U.S. outdoor recreation market; therefore, not quite as sensible. Still, probably the next best thing.

Note that setting up different gearing is still simply a case of obtaining common bicycle parts, swapping them in, and adjusting chain lengths.

GRIT chairs come with I.S.O. 559 mm wheels. In the bicycle world, this is understood as a type of 26″ size; in the wheelchair world, 25″!

Compare with other outdoorsy chairs for ease of trekking.
