Magura Boltron Suspension Fork for E-Mountain Bikes

The Magura Boltron suspension fork has been designed specifically to meet the unique demands of suspension forks on the modern E-Mountain Bike and works with either 27.5” wheels or 29” wheels. Featuring a super-stiff steering tube and upside-down fork legs that can cope with the increased speeds and subsequent forces produced by a faster, heavier E-MTB the Boltron has been developed in partnership with engineers from a motocross background to utilise their experience of working with the bigger forces typically found in motor sport.

The Magura Boltron includes a super-stiff 20mm thru axle to increase stiffness at the hub and provide enhanced steering precision while the upside-down fork leg construction with friction-optimised coatings provide extremely precise responses to both large and small hits. The Boltron E-Bike suspension fork is particularly easy to set up with the negative air chamber’s pressure being set automatically and the compression damping adjusted via shims; this just leaves air pressure and rebound adjustments for the rider to fine tune to their riding preferences.
