Herrmans H-Black MR8 light
The MR8’s long and even light pattern gives you excellent near-field illumination without dark spots. Side windows provide additional peripheral lighting. The MR8 delivers strong light output – up to 180 lumens, 60 Lux.
Shimano Nexus hub dynamo
By building the Nexus dynamo in the front hub, we use less sensitive external parts. Not only does it look better, it is also safer and more reliable.
Shimano hydraulic disc brake
Shimano hydraulic disc brakes ensure that you come to a stop no matter what the circumstances are, so you can feel safe even when you're riding at high speeds.
MIK rear rack
Our MIK-compatible racks make it a piece of cake to secure any MIK accessory. Click it on, and you’re off!
Tough Bontrager Hard-Case tyres help keep punctures from slowing you down.
