TYPE OF RACK DESIGN RECOMMENDATION & CAUTIONS
NON-FLOATING FORK MOUNT
& REAR WHEEL TRAY
With this type, a mechanism pulls the
two sides of the fork in at the same
time, and pulls both sides in the same
distance.
Example: Thule Peloton.
Not recommended for either carbon or aluminum bikes.
If one dropout is slightly thicker than the other dropout, all the
clamping force is applied to the thicker dropout. The high force
on the one thicker dropout may crack a carbon dropout. The
thinner dropout may move in the rack causing wear and
abrasion, The fork blade attached to the thicker dropout takes
most of the loads caused by 70 mile per hour wind and bumps.
The result may be damage to your fork.
HANGER RACK
On this type the bicycle hangs on two
arms projecting aft from a trunk
mounted rack
Not recommended for either carbon or aluminum bikes.
Do not use on bikes with carbon fiber tubes.
The point loading where the arms contact the underside of the
tubes may crack the tubes. Additionally the lower part of the
bike is difficult to secure, and it may move, causing chafing and
structural wear. Additionally when two bikes are mounted on
these racks the contact points between the bikes may be
cracked or chafed, causing structural damage.
