over a decade the team at Balfa has been building good
bikes, with two commom themes, innovation and dependability.
The BB7 is both.
An aluminum main frame is connected via sealed bearings
to a steel chromoly swing arm with one piece bent chain
stays. The steel rear end enables the use of smaller
tubing for greater tire clearance. A
"Drive High" high pivot pulley system keeps
the chain next to the pivot and removes all problems
of chain tension while keeping the rear triangle fully
active and allowing for almost unlimited travel (9 inches).
Finally, the design of the suspension supports "Parallel
Trajectory". The simplest explanation is your rear
wheel follows the same path as your front wheel when
under impact while riding.
One of Balfa's sayings is, "Strength dictates the
weight, not the other way around." Probably one
of their reasons for using steel in their frames, but
definately why they can offer a 1 to 2 year warranty
"no matter what you use your bike for". The
proof is in the customers opinions which seem to be
strong and loyal.
may just have to go get me one and see if I convert
