Two styles. Road bike and mountain bike. Single brake lever operates both front and rear brakes simultaneously for safety and control. Designed to fit standard diameter handlebars. Right or left mount and single-handed operation. Levers only - no brake lines provided. TRS suggests that this brake equipment be installed by a certified bicycle mechanic to ensure proper adjustment. Caution! Front brake should never be adjusted to engage before rear brake with this single-handed brake lever system. Actual brake lever style may vary slightly from photo.
The TRS Criterium is a simple recreational accessory designed to snap on and off one inch diameter, smooth, bare bicycle handle bars.
One inch diameter bars are standard in the bicycle industry. The cylindrical gripping area of the Criterium is offset below the centerline of the device to more accurately mimic true hand to handlebar position.
The Criterium comes in two models the Criterium 70 and the Criterium 85. Children, small sized adults and less aggressive riders will probably prefer the Criterion 70 because it snaps on and off the handlebars with less effort. The Criterium 85 is designed for average to larger adults or more active, aggressive riders The Criterium 85 requires more effort and force to get on and off the handlebars. Neither model is recommended for competitive bicycling. Neither model is recommended for children less than eight years old.
The Criterium is constructed of a durable synthetic polymer. It is passive in that it requires no cable for operation. The Criterium gets its gripping and release force from its shape and the flexible properties of the synthetic material from which it is molded. The Criterium has no moving mechanical parts or adjustable release mechanisms. Depending upon the weight of the rider and the forces involved the Criterium is designed to push onto and pull off the handlebars under load. This elastic type action provides some margin of safety should the rider fall or wish to dismount quickly.

*Release loads were measured using one inch diameter smooth, bare metal handlebars without any tape covering. The load applied was a straight pulling force. No torque was applied. Tape, foam or fabric coverings will increase the amount of force and torque required to push on and pull off the Criterium bicycle accessory.
*Regular white medical or athletic type adhesive tape will increase the effort required to pull the Criterium off the handlebars by as much as 60-90%.
*Standard cork, vinyl or foam backed bicycle handlebar wrap increases the bar diameter significantly! The result is that it will take approximately 30% more effort to pull the Criterium from the handlebars than when using smooth, bare handlebars.
