6.5.6.1 Replacing the handles

Not included in price
Handles with bolt clamps are components which
§
may be replaced without approval.
If there is pain or numbness in the index, middle
finger or thumb, this may be due to excessive
pressure on the exit of the carpal tunnel. On
longer rides, this can increasingly cause hand
fatigue and make it more and more difficult to
maintain a correct hand position.
In the case of ergonomically shaped handles, the
palm rests on the anatomically shaped handle. A
greater contact surface means that the pressure is
more evenly distributed. Nerves and vessels are
no longer squeezed in the carpal tunnel.
Moreover, the hand is supported and held in the
correct position so that the hand can no longer
bend.
If the pre-mounted handles are uncomfortable or
cause pain or numbness in the index, middle
finger or thumb, ergonomic handles, bar ends or
multi-position handlebars should be used.
