Can you convert a 135 mm Chris King single speed hub to 142? Yes!

142x12mm Rear ISO SS Thru Axle

If, like me, you've spent good money on a Chris King Single Speed rear hub you've probably found that you've been limited to frames with 135mm rear hub spacing.

However, new frames, like the Niner ROS 9 (which is next on my shopping list!) only come in 142 x 12 spacing. Fortunately for us the chaps at Chris King have realised that 142 is now the default premium mountain bike frame spacing and they're now offering a suitable conversion kit.

Beware! There are two conversion kits

There's the original 142 conversion kit, but it's NOT compatible with your 135 spacing Single Speed hub.

• Don't buy this one: 142x12mm Rear ISO Thru Axle
• Instead buy this one: 142x12mm Rear ISO SS Thru Axle
• You'll also need to buy the High Profile Rear Adjustment Clamp as well to complete the conversion

How to convert the hub

In time I fully expect to make the upgrade myself and will post a how-to guide, but if it's anything like how easy it is to convert a Chris King front hub, then it should be a straight forward affair.

Hope this helps someone.
