Stiffmaster

Are you interested to learn more about the technical background?

Upcoming questions:

 

1. Do I really feel the improved stiffness?

 

This depends on:

- Rider weight

- Stack height

- riding skills

 

If you have 50 kg, zero spacers with zero stack headset and you are riding very slow?  Then you will not feel that much improvement.

 

If you have 80 kg, normal stack height and want to go fast, you will feel it! The improvement is 40% less elasticity. You will have the slight touch of a double crown fork.

2. Is a stiffer cockpit better?

 

Question: if you can choose between a flexy stem and a stiff stem - which one would you choose? Would you ever mount a more flexy stem to improve your cockpit feeling? 

Be honest, you will never mount a more flexy stem if you have the choice, so yes, a stiffer headset is the better one!

Still stiff, when others are already done!

 

This headset (upper part only!) increases the stiffness of your 1 1/8" steerer tube. It's not about the stiffness of the fork, its about the stiffness of the handlebar for onesided loads.

 

Fast turns, sprinting or horrible rock gardens, a stiffer cockpit is neccessary for fast and hard riding. But it is not done with a stiff handlebar. The handlebar itself should have some small flex for symmetrical loads to increase comfort, but onesided loads should not make the system bend.

 

The one-piece spacer increase the stiffness further (one is included).

 

General improvement of the stiffness is about 40% ( measured at 26mm stackheight) compared to a standard headset incl. spacer.

 

Next to this the bearings of Stiffmaster are so huge and filled up with salt-water-resistant grease, that you can forget your headset totally. 

 

Note: the minimum stack height is 14mm, but you should use always a Intend Spacer. With the lowest spacer the stack height is 15,5mm and this fits to every stem!

 

Manual: www.intend-bc.com/user-manuals

  • 77g weight upper shell excl. spacer
  • 14mm stack height
  • suitable for ZS44 headtubes, (IS41/42 is not planned for the future)
  • one-piece spacers available in 20, 13, 7, 1.5mm
  • 3Nm bolt-torque
  • available in black, blue and raw - but the lower cup is ALWAYS black (differs to some pictures)

Price: 79 Euro (incl. VAT)

 

The Stiffmaster is already ready to order. Order now

 

Note: you can use all conventional spacers in addition to the Intend spacers. But the first always should be an Intend spacer. I do not offer "normal" spacers. You can get all Intend spacers individually if you do not know your riding height yet.

    Does this come as a complete headset or just the top? if its the top only, do you make a bottom as well?

    My current setup was 25mm of spacer on a zero stack headset, I decide to go for the intend stiff master only because I were curious about the behaviour.
    The result is pretty noticeable especially in berms and rough sections, where the steering feel more precise and direct, and during braking. In this latter case the bike seem a little less forgiving and compliant, but this is the price for improved overall accuracy. My weight is 82kg ready on the bike, the bike is a Trek slash alu 2016 with lyrik 170.
    Quality is high, a nice piece of engineering.

    Really love this part. Installed it, feels like I have a double crown fork now. What makes it a cheap and light upgrade. Thanks! Now I want it on all my bikes!
