What is it?
If there's any doubt that 27.5+ would take off this year, they were erased by FOX's introduction of this 27.5+ fork with 110mm hub spacing. This wider hub allows huge 27.5 tires like a 3.0 or 3.5 inch.
Existing front wheels use 100mm hub spacing with 100mm between the inner edges of the dropouts. This new 15×110 standard adds 10mm to the width of the dropout where each spoke flange is 5mm further from the center of the hub. The brake rotor position is moved out 5mm as well.
Why?
There's no doubt that rims are getting wider. With the advent of carbon and better construction, lighter wide wheels are available now and riders have been impressed with their performance. Sidewall support is isolated from tire pressure and riders are able to enjoy more support, traction and comfort as they lower tire pressures.
Tires are getting huge too. 2.3 is the current standard but many riders who've been trying 3.0 tires have been floored by its performance. The grip is unprecedented and the speed is surprisingly good depending on terrain.
So FOX answered the call from several bike manufacturers to create a fork for this new type of bike with 3.0 inch tires. Who are these manufacturers? We'll find out at Sea Otter which we suspect will trend towards Sea Otter +.
Will this affect the current 100mm spacing forks?
No. They will be produced and will be continue to be the mainstay of the FOX line. This fork comes as an addition to existing ones.
