It appears to be a 27.5 Santa Cruz V10 rather than one of the 29ers The Syndicate have been running on the downhill circuit this year. Though, this fork also appears to be a different prototype to the one shown in most shots.

If you’re confused about the Obsys, BOS and Sunn names, you can read more here, but basically: Obsys was a trademark of Sunn, registered in November 1996. It stood for Obstacle System, but was designed by Olivier Bossard, and some people misinterpret it as “Oliver Bossard Suspension System”. In 1999 he founded BOS:

“BOS Engineering has been created by Olivier Bossard in october 1999. Olivier came from Sunn Bycicles, where he was in charge of the R&D, and especially of the factory team.As a great fan of motrosports, but also as a good MX and MTB rider, Olivier has always been facinated by the suspension systems. The bikes that he created at Sunn, for the downhill factory team still remainthe most evoluated of the MTB history, and the most successful at this time, with many world tiltes claimed.

During the first months of Bos Engineering, the company is involved in MTB, with Nicolas Vouilloz, rally car, with Serge Jordan ; motorbike with many top enduro or MX riders. Bos activities range is wide : from tuning suspensions to building the first dampers, and designing frames or drive trains for other companies.”
