OEM spec requirements

1. Brake Bosses

The brake boss location should put the brake pads in the center of the brake arm channel or above the center line by up to 3mm. Any brake boss location that puts the brake pads below the center line is NOT acceptable.

The brake boss location is important for two main reasons:

  1. Easier setup of the brake pads.

2. Better performance of the brakes. If the pads are below the center line, the lever may not pull enough cable causing a spongy brake feel.

2. Brake Ratios

The brake boss location should put the brake pads in the center of the brake arm channel or above the center line by up to 3mm. Any brake boss location that puts the brake pads below the center line is NOT acceptable.

Formula = C*B/A ≥ 7

The brake lever/arm ratio is important for these reasons:

  1. Easier setup of the brake pads

2. Better performance of the brakes. If the lever does not pull enough cable, it will dip into the handlebar before fully actuating the brakes.

3. Cable Routing

Standard Frame

See routing above for standard frames near the seat tube. If looking at the top tube like a clock, the rear brake cable should go at “7 o’clock” and the front brake cable should go at “5 o’clock”. This will push the front brake housing coming out of the Slidepad away from the rear tire.

 

Step-Thru Frame

See routing above for standard frames near the seat tube. If looking at the seat tube like a clock, the rear brake cable should go at “7 o’clock” and the front brake cable should go at “5 o’clock”. This will push the front brake housing coming out of the Slidepad away from the rear tire.

 

4. Approved Standard Brake Pads

These are a list of standard pads we have tested and approved to work well with SureStop. If your brake supplier or brake pads you are using are not on the list, please contact us and we will test them.

5. Rim Braking Surfaces

Here is a list of the braking surfaces we have tested and the results of the tests.

 

Alloy – Machined

  • Result = Excellent
  • Great braking performance in dry and wet conditions.

Alloy – Brushed

  • Result = Recommended
  • Good braking performance in dry and wet conditions

Alloy – Anodized

  • Result = OK
  • Good braking performance in dry, but reduced performance in wet conditions

Alloy – Painted

  • Result = NOT reccommended
  • Unpredictable braking performance based on variation in paint

6. Never Spec Power Modulators on the Front Brake!
