Headset Press (M8 Version) *** Buy one, get one 30% off any mix of pullers and presses (applies to individual tools only, not kits) *** This tool is designed to install the cups that hold the headset bearings on many brands of bicycle. The M8 version uses the same diameter of threaded rod as our frame and hub presses, so the same T-bar handles can be shared with our other presses. We have a heavier duty M12 headset press here. A complete tool consists of a pair of drifts (sometimes called spacers or bushings) with several diameter steps, and a threaded rod to pull the drifts together. Each press can be purchased with either T-bar handles or simple nuts. Both of these options include a pair of drifts and one of our new precision-engineered stainless steel threaded rods. The 125mm-wide T-bar handles make the tool super-easy to use, while the nuts are a functional and cheaper option and are used with normal spanners. The T-bar version now comes with a set of thrust bearings to make the tool run extra smooth. A 'drifts only' option is offered for buyers who have already purchased a kit with the T-bar handles or the nuts before, and only need the drifts. An optional centring cone is avaliable separately here to assist in installing the first cup. The threaded portion of the rod supplied with this press is 300mm long, with additional 8mm of non-threaded length at each end to lead the handles/nuts on and off. Our drifts feature a number of stepped diameters: one drift has steps at 25.7mm, 29.6mm, 36.5mm and 47.5mm, while the other drift has steps at 29.6mm, 36.5mm, 47.5mm and 60mm. These steps allow the press to suit 1", 1 1/8" and 1.5" headset cups from most manufacturers. 8mm precision-engineered stainless steel threaded rod compatible with our other frame and hub presses Shipping is fast and free in the UK Combined shipping for international customers buying more than of our extractors or presses How To Use Two drifts are supplied. The stepped shape of the drift ensures that the press remains centred on the cup. Grease headset cups lightly before installing. Select the drift that fits the cup best. The other drift will be used against the other end of the headtube. For best results press one cup at a time. Tightening the nuts or handles draws the drifts together, pressing the bearing into place. Repeat the process using two stepped drifts to install the second cup. Compatibility While it appears that the industry has standardised headtubes to 1", 1 1/8" and 1.5", the reality is a bit more complicated! Each of these three 'standard' sizes exists as Traditional (external), Integral and Internal formats, resulting in some 7 or more actual headtube diameters in use. To add to the complication, this tool must interface with the inside of the cup (not the headtube). The cup shape and diameter varies according to each manufacturer's specific design, resulting in hundreds of possible permutations. It is therefore impossible for any headset cup press to closely fit in the same way that our regular bearing presses do... The stepped diameters have been chosen to fit the widest variety of headset cups, but some space should be expected and is acceptable. If you are unsure about compatibility with your own headset please compare the dimensions given for our press drifts above with your headset.
