SRP Mr. Grumpy cantilevers. $90 per wheel at EU Cycle Imports.
The SRP Mr. Grumpy has been around for a long time. It was maligned for its relative lack of stopping power but has recently made a comeback for its light weight, unique look and copious amount of rim clearance. It had features typical of the European style wide profile cantilevers, pivoting directly on the brake bosses, though the pivot to cable anchor is short and the angle is so wide that the arms are below the pivot.
Impressions: The SRP Mr. Grumpy cantilevers provide more clearance at the rim than any other brake I’ve yet reviewed. The spring tension is also greater than other similar cantilevers without adjustable spring tensioners, such as the TRP or Spooky. The combination of clearance and high return spring tension is ideal for muddy conditions when the cables and rims can get clogged with muck.

The short arms certainly yield reduced leverage and, therefore, reduced braking power. The angle of the arms affects the cable pull angle, further (though slightly) reducing power. Even run with KoolStop salmon pads, I had to squeeze the levers harder to overcome the spring tension and to provide enough pad-rim pressure to stop. For set-up tips and a more comprehensive brake and brake pad review, check out Cyclocross Magazine Issue 7.
In the box: no brake holders or pads, but titanium mounting hardware, straddle cable and standard stamped metal hanger.
Weight: 75 g without pads or holders.
Geometry: Pivot to cable anchor 34 mm, pivot to pad face 41 mm, angle 136 degrees.
Average clearance: 9 mm cable pull yields 7 mm pad to rim movement per side.
