Better Boost Adapter KitsDesigned for:Converting compatible DT-Swiss 15x100mm hubs to 15x110mm Boost standardThe new Better Boost Adapter Kits allow you to keep your existing 15x100mm front wheel as you upgrade to a new Boost 15x110mm fork.What makes them better?There are other conversion kits on the market, but ours is the best.  One competing kit consists of two loose 5mm axle spacers that are a pain to install and are easily lost during wheel removal. Another provides you with just one endcap and requires that you re-dish your wheel to re-center it in your fork. The Better Boost Adapter Kit consists of two precisely machined end caps and a rotor spacer (and requistite bolts), and it requires NO DISHING.What hubs are compatible?There are currently two Better Boost Adapter Kits available:Better Boost Adapter Kit for DT-Swiss 350 15x100mm 6-bolt front hubsBetter Boost Adapter Kit for DT-Swiss 240s "Fifteen" 15x100 6-bolt front hubsOther compatibility info:Better Boost adapter kits are not compatible with QR or 20mm hubs, nor are they compatible with those featuring a Shimano Centerlock brake mount.
