MTB-XC  Fast Forward

Fast is not enough? No problem! The AmEn1 boosts the performance of your race gear. Not just light weight, but strength and a full wide gear range, are all key for maximum Cross Country performance.

VYRO AmEn1

Our first series products are now reduced! The AmEn1 is superlight coming with a 24mm alloy spindle. We recommend this crank for hard tail MTBs only due that it has a fixed shifting point. For Full Suspension Mountainbikes the AmEn 2.0 is the right choice which has a widely adjustable shifting point that can be adapted to the SAG (negative suspension travel).

VYRO AmEn 2.0

The AmEn 2.0 offers numerous improvements. It has an adjustable shifting point even when mounted via the ISCG-Interface. This is necessary for long travel full suspension mountainbikes because the chain line changes when the rear suspension is working. This crank can be mounted to Press Fit and threaded bottom brackets. The AmEn 2.0 has a light but thick wall 24mm alloy spindle. For aggressive riding and heavier riders we recommend the FrEn 2.0 with CrMo spindle.

Our Technology

The big chainring is segmented into four parts that swivel into the chain line, smoothly and seamlessly picking up the chain. – Our technique provides a natural, harmonic shift.No front derailleur and therefore no chain/cage rattling on downhills.Smaller gear steps help you find the optimum ratio, and the little chainring helps you climb steep sections, especially with longer travel bikes.Fits on all frames with BSA and/or ISCG03/ ISCG05 standard bottom bracket mounting.
To better protect your Vyro Crank from impacts you can also opt to add the optional Bash Guard.
