    What are Offset Bushings?

    Offset Bushings are a type of shock bushing (or shock hardware) which adjusts the geometry of your bike to improve the handling characteristics by lowering the bottom bracket and slackening the head angle. They work much like a Flip Chip in many bikes (and are still compatible with Flip Chip frames). We custom make them for your specific bike / shock combination. If you're just looking for standard shock bushings rather than offset - we sell these too.

    They've been used for years by top riders worldwide in everything from DH to Enduro and even XC racing to help them feel more comfortable on their bikes and ride faster.

    In one test with a top DH World Cup rider, they found they were 4 seconds faster over a lap of Fort William, Scotland after fitting Offset Bushings  - a difference of up to 25 places!

    Our Offset Bushings even scored a top ten finish at the Red Bull Rampage whilst being used by Rémy Métailler.


    How they work

    Offset Bushings simply replace your original shock hardware. That means pushing your old hardware out and pressing your new Offset Bushings in. When installing, make sure the offset holes are facing towards each other – towards the centre of the shock. This mimics the effect of a slightly compressed shock; which will in turn lower and slacken the geometry of the bicycle. Find out how to install here.

    One common misconception is that they will reduce the amount of travel your bicycle has - they do not. The stroke of your shock remains constant so your travel will not be adjusted at all.


    Offset bushings


    Material choice 

    Our shock bushings are machined from both brass and aluminium. We put a lot of time into finding reliable partners to source material from – our brass rod is machined to very high tolerances to provide the best fit possible.

    Brass has self-lubricating properties which makes it a perfect material for the job. It's often used for industrial bushing purposes due to this. We use aluminium for our spacers due to its light weight. Brass offers an ideal balance between performance and longevity when it comes to bushing applications.

    Whilst other manufacturers might choose to use materials such as steel or titanium for this purpose, we find that bass offers the best mix of qualities for our products. Keep in mind that shock bushings are wearable items, as they're designed to wear before your shock bolts do. If your shock bushing is made from a harder metal than your shock bolt it can potentially cause premature wear to shock bolts which can result in failure and added expense.

    Adjustment and sizes

    The adjustment you'll get when using Offset Bushings can change slightly from one bike to the next. This is down to shock length & leverage ratio along with the shock hardware bolt diameter. On average you should expect the following adjustment.

    Pair of Offset Bushings

    • 6mm bolt – 3mm offset | 1.5° HA | -15mm BB
    • 8mm bolt – 2mm offset | 1.0° HA | -10mm BB
    • 10mm bolt – 1mm offset |5° HA | -5mm BB

    Single Offset Bushing

    • 6mm bolt - 3mm offset | 0.75° | -7.5mm BB
    • 8mm bolt -2mm offset | 0.5° | -5mm BB
    • 10mm bolt - 1mm offset | 0.25° | -2.5mm BB

    Whether you have an Intense or an older Lapierre which use 6mm bolts, or a recent Commencal which use 10mm bolts, you’ll notice a significant improvement to your bikes handling after installation.

    Frames with 8mm bolts are the most common - these are commonly used by Specialized, Orange, Santa Cruz & many others. 

    We produce hardware for all shock types

    Including but not limited to;  RockShox, Fox, Cane Creek, Manitou, DVO, Extreme Shox, X-Fusion, BOS & 5th Element. We produce shock bushings in 12.7mm diameter (industry standard) only. Please note that older Manitou and BOS shocks use 12mm diameter bushings and are not compatible. Please see our Supported bikes page for more info.

    If you have any questions, please do get in touch. We aim to reply within a couple of hours.

    Mountain Bike Rider produced a video all about MTB geometry and have a section explaining how Offset Bushings work, you can check it out below from the 2:30 mark.
