"That's a product I won't be able to take off my bike for racing... I was 1 second per minute quicker with the TMD”​- Jesse Melamed.

 

Mass That Matters

 

The 250g mass uses every available space inside the fork steerer for maximum performance.​

 

End Stroke Control​

 

V2 features elastomer bumpers to deliver even more performance on the biggest impacts.

 

No Tuning Required​

Carefully chosen springs with extended travel allow the mass to respond to inputs quicker than ever whilst still offering control through the biggest hits.

    Compatibility 

     

    Optimised for bikes with a steerer length of 180mm+. If your steerer shorter than this, you will need spacers above the stem to be compatible. Not sure how to measure this? Check our guide here.

    Aluminium and Steel, Tapered and 1 1/8” , oval or cylindrical steerers are all compatible. For use on single and dual crown forks.

     

    Servicing

     

    TMD is designed so the springs never use more than 80% of their available travel. By avoiding full compression, spring life is significantly extended and replacement is rarely required. If spares are ever needed you can pick them up here.
