Profile Design GMR 50/65 Twenty-Six Carbon Tubeless Rim Brake Wheelset - Shimano
$2,248.99
The GMR 50/65 is oriented towards triathlon use - the deeper rear wheel helps improve stability in the aerobars along with a small aero boost.
For road racing the wheelset suits a rider that intends to be on their own at some stage of the event.
The GMR 50/65 Tubeless Rim-Brake is optimized for wide tyres with lower tyre pressure to meet the performance needs of modern riders in search of low rolling resistance and high compliance. With an internal width of 19mm, the wheelset is well suited for rough roads and tests fastest with a 28mm tyre in the majority of wind angles.
Brake Performance
Specifically formulated to withstand the same heat their rims can take on, their brake pad compound is exclusive for GMR Series wheelsets. Using a specially formulated rubber compound, durometer and friction agent, theydeveloped a proprietary brake pad and reduced braking distances over that of other carbon fiber wheelsets.
