Riders on 1-1/8 inch threadless bikes who want a taller, more upright position without replacing the fork.
The Satori Heads-Up 4 is a steerer extender for bikes with a 1-1/8 inch (28.6 mm) threadless fork. It clamps over the top of your existing steerer with two M6 bolts, then your stem mounts on its own 28.6 mm upper section, raising the handlebars for a more upright, relaxed position.
It's machined from AL6061 aluminium, stands 117 mm tall and weighs 240.5 g. A set of spacers (2 x 5 mm, 1 x 8 mm and 1 x 10 mm) lets you fine-tune the height, and it comes with its own top cap and long bolt to preload the headset through the riser.
Riders use it on hybrids, commuters and older mountain bikes when neck, back or wrist comfort calls for a higher bar and there's no room left for spacers.

Great for
Maybe not for
Fits 28.6 mm (1-1/8 inch) threadless steerers and takes a standard 28.6 mm threadless stem. Check your brake and gear cables have enough length for the extra height.
Fitting it safely
Line the riser, stem and front wheel up straight, then preload the headset through the long bolt before tightening the clamp bolts. Satori's manual calls for the stem and riser bolts to be torqued to 9 to 10 Nm, with no movement between the riser and the fork. If your cables end up tight, bring it in and we'll fit it and re-route or replace them.
