WARNING: CYCLING CAN BE DANGEROUS. BICYCLE PRODUCTS SHOULD BE INSTALLED AND SERVICED BY A PROFESSIONAL MECHANIC. NEVER MODIFY YOUR BICYCLE OR ACCESSORIES. READ AND FOLLOW ALL PRODUCT INSTRUCTIONS AND WARNINGS INCLUDING INFORMATION ON THE MANUFACTURER’S WEBSITE. INSPECT YOUR BICYCLE BEFORE EVERY RIDE. ALWAYS WEAR A HELMET.

COMPATIBILITY & INTENDED USE

CONDITION 2

The Double Barrel Brake Lever is intended for use under the guidelines of ASTM Condition 2. This is a set of conditions for the operation of a bicycle that includes Condition 1 (paved roads) as well as unpaved and gravel roads and trails with moderate grades. In this set of conditions, contact with irregular terrain and loss of tire contact with the ground may occur. Drops are intended to be limited to 15cm (6") or less. 

This lever will work on bikes equipped with flat bars that are 22.2mm in diameter at the grip. It is intended to be used with long-pull calipers only.

TOOLS REQUIRED

• 5 mm hex wrench

• Torque wrench that measures in Nm

• Cable cutters

• Tools needed to adjust your brake calipers

INSTALLATION:

1. Remove your old brake levers. You may need to remove your grips or shifters in order to do so.

2. Slide the Double Barrel Lever onto your handlebar and replace your grips and shifters if you removed them.

3. Adjust the angle and position of the lever and tighten the fixing bolt to your handlebar manufacturer’s specifications or to 4Nm, whichever is LESS. Do not exceed 4Nm.

4. Install cables into the lever by aligning the slots on the barrel adjuster with the slot on the bottom of the lever body and inserting the barrel of the cable into the lever.

5. Unscrew each barrel adjuster two turns to allow fine tuning.

6. Route your housing to avoid sharp bends and make it long enough that you can turn the handlebar fully in both directions without pulling it tight.

7. Install the brake cable to the caliper per the caliper manufacturer’s instructions.

8. Adjust the cable tension so the lever is pulling the calipers equally or is biased to pull the rear brake harder than the front. WARNING: Adjusting the lever to pull the front brake harder than the rear could result in loss of control and a crash when the brakes are applied.

9. You can use the barrel adjusters to adjust cable tension to account for brake pad wear, but again, make sure the calipers pull evenly or are biased toward the rear brake.

ONGOING MAINTENANCE

Periodically inspect and adjust your brake calipers per the caliper manufacturer’s recommendations. Inspect your brake cables before every ride and replace immediately if you see signs of rust, corrosion, or fraying. Periodically check that the hardware on your brake levers is tight.
