Shout about this product!


Fit the Reacheriser to tune the effective toptube length of your frame. By mounting the bearings externally we can create an eccentric cup to move the steerer 5-7mm forwards or backwards depending on your requirements. Breathe fresh life into an old frame by tweaking your geometry to improve your handling. This adjusts your effective toptube length which is not the same as fitting a longer stem, as it moves the pivot point of your steerer. Choose from our comprehensive range of fitments, to suit the most common sizes. Fully sealed cartridge bearings and custom made NBR wiper seals keep out the dirt and water, giving you a long lifespan in the worst conditions. An innovative retained compression ring and split crown race makes assembly easy.

New range of high quality headsets manufactured in the UK by Superstar's in house manufacturing facility in Lincoln. Manufactured to the highest tolerances these headsets are a perfect fit and forget, multi-sealed replacement for the cheap and nasty product normally fitted to complete bikes to keep manufacturing costs down.

Complete kits designed for the most popular frame fitment.

  • This headset will only work with 1 1/8" steerer tube forks (except taper specific model).
  • Check you have sufficient clearance inside of your headtube to allow fitment, some headtubes reduce in diameter internally and will not work.
  • We manufacture our headsets to the IS standard set out by Cane Creek. The tolerances are measured in microns, but if your headtube is oversized, ovalised or worn your headset may not function correctly or creak. This is not a fault with the product but a faulty frame.
  • We reccomend careful pressing with a quality headset press. Allignment lines are engraved into the cups.

Tech Specs

  • Stack measurements include top cover or crown race.
  • Note that some manufacturers list cup only to make them appear shorter than they are.
  • Angle headsets are the mid stack height and will vary by a mm or so depending on angle.
  • Our headsets are highly sealed with custom moulded wiper seal, this adds approximately 2mm over unsealed headsets but we feel this is essential to long service life.


We manufacture all our headsets inhouse in our UK CNC machine shop in Lincoln. Heres a little video of the topcovers being machined on our barfed Doosan Lynx Lathe. By using a high tech dual spindle machine we can make finished parts in one hit, and then run the machine 24/7 to get high quality with great prices direct to you the customer.

    Fitted on of these headsets to my new frame.. I am very tall so need all the extra reach i can get... This headset worked a treat. I am from an engineering background and the quality of the headsets are also amazing. even the rubber weather seal and base plate are much better than some other high end stuff i have seen... Even the packaging gives a premium feel. 5 Stars all day from me
