We wanted our brake to be really light, strong, effective, easy to retrofit your current rollerskis and simple to use. In the end we came up with this unique brake like none other on the market and one we love to use. To engage, put one foot forward to get a stable stance and pull up on the handle. The brake for existing 45 mm axles adds just 52 grams (excludes weight of cord, handle, and waist belt) to the rollerski which isn't enough to create any noticeable tail drop.
The skinniest two for existing 40 and 45 mm axles are shipped with 45 and 55 mm axle bolts respectively. The largest two for Marwe 610 and Swenor Elites ship with 55 and 60 mm axle bolts respectively. Bolt lengths are from under the head to opposite end, and not overall length.
Braking Installation and Safety
1. Remove one of your axle bolts as youíll be using the longer bolt that we ship to hold the brake on.
2. Put the brake arms over the outside of the forks with the spring on the back side.
3. Place a lock washer included on each side between the forks and brake arms. These are important as the lock washers prevent rotation of the brake. Put the axle bolt through and adjust for its vertical positioning by having it clear the top of the wheel. Tighten axle firmly.
4. To adjust for skierís height, the bungee section above the pull handle can be adjusted by sliding more or less through the cord lock and you can cut off the extra once you get a feel for how much length you need. The cord should be snug. You can detach it from the waist belt and attach to a water bottle holder as well. No need to retie any knots for installation.
5. You can also adjust the braking power some by bending the round profile of the brake lever to grip the wheel more or less by using a pliers. The way it is shipping is for good braking power on hills, but if you feel itís too much grip at lower speeds you can bend out both sides of the lever some to give it a flatter profile (depending if itís used on new or used wheels affects this also). By flattening the profile itíll be smoother at low speeds but not as powerful on steeper hills.
6. Check before rollerskiing to make sure everything is operational and nothing tangled, and that the connection to the brake level looks secure with no fraying or loosening. Heat build up on medium size hills is ok but extensive long hills could create a lot of heat buildup, so we advise avoiding huge hills or using in the mountains. The way we tie the knot on the brake lever through a metal ring first and then loop the end through two more times is done to prevent heat build up from affecting the connection and secondly to prevent vibration. Be aware braking power is reduced in wet conditions.
