It's most important that your handlebars are at the correct height and reach to be comfortable for YOU. Sometimes this means that the brake levers will hit the top tube, if the bars turn too far. This usually results in paint damage and may also damage the top tube.

This product is designed to prevent the brake levers from hitting the top tube, if the bike falls over, or as a result dropping the bike in low speed incidents.

The Lock Limiter will NOT prevent the bars from hitting the top tube, as a result of more serious incidents. The Lock Limiter fits all Thorn Mercury head tubes. The 2 piece design means that headset removal in not necessary.

The Striker will fit the steerer tubes of all the different Mercury forks, provided that 10mm of spacers can be removed to make room for it.

Please Note: The Striker locking screw will need to be loosened every time a head set bearing adjustment needs to be made and it will need to be re-tightened afterwards.

This product will also fit other manufacturers' frames with a stepped 39.5 / 36.5mm diameter top tube, provided there is at least 10mm of parallel head tube standing above the joint with the top tube. The striker will fit all 1 1/8" steerer tubes, provided that 10mm of spacers can be removed to make room for it.

21 Dec 2014

I'm afraid not the correct version that will fit to a Nomad Mk2 frame is the 37mm option which is SJSC part number 34956.
