It's only the end of March 2008 and Fox Racing Shox is already debuting its 2009 lineup. The new collection will likely be best remembered for its new ‘15QR' 15mm thru-axle standard which the company will offer as optional equipment for all of its 32mm chassis segment (with the exception of the F29).
Fox doesn't intend 15QR to replace any existing thru-axle format and indeed, the industry-standard 20mm system is heavily utilized elsewhere in its range. Rather, Fox aims 15QR at cross-country and all-mountain riders who are looking for more steering precision than a standard 9mm quick-release configuration but less weight than a typical 20mm setup. According to Fox's figures for its 2009 forks, 15QR is 25 percent stiffer in transverse shear and 15 percent stiffer in torsion than the standard open dropout quick-release versions, but only adds about 100g - excluding the hub but including the 15QR axle and standard skewer.
