Headset Press (Heavy Duty M12 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 M12 version uses a heavy weight 12mm threaded rod for extra stiffness and durability, intended for professional workshop environments. [Note that the M12 rod and T-bars are not compatible with our other press as our other press use an smaller 8mm thread. We have an M8 headset press here] Our M12 Headset Press is sold as a complete set, comprising a pair of T-bar handles, a 12mm threaded rod, a pair of thrust bearing supported by heavy duty brass washers, one larger and one smaller stepped headset drift, and a large centring cone. The threaded portion of the rod supplied with this press is around 305mm long, with additional 10mm of non-threaded length at each end to lead the handles/nuts smoothly on and off the thread. 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. Heavy duty 12mm precision-engineered stainless steel threaded rod Two stepped headset drifts and one large centring cone included 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. For best results press one cup at a time. Use the centring cone against the other end fo the headtube when pressing in the first cup. 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.
