Hope Head Doctor 1 1/8

Hope's Head Doctor replaces the traditional star fangled washer and top cap. Two alloy wedges are pulled together to allow the top cap bolt to provide tension in the headset bearing.

It's a good idea to check the wedges are greased by disassembling them first, grease internal surfaces and the big threaded bolt, reassemble with the o-ring and insert into steerer tube. Make sure the top of the device is at least 12mm below the top of the steerer and then tighten with an 8mm allen key to expand the wedges and clamp it tight in the steerer. The Doctor is then installed and can be used as normal to tension the headset - do not torque up the the bolt - it is for tensioning the headset only!


Hope say :-

Tired of re-tightening your headset? So are we. To combat this common problem we have produced an engineered solution. Two aluminium wedges simply pull together and expand inside any size of steerer giving you a solid thread to pull the stem down. Sounds simple? It is. This is topped off with a laser engraved, anodised aluminium cap and aluminium bolt.

  • Fits 1 1/8" steerers (internal up to 26mm)
  • Weight : 29g
