SuperB 275

The SuperB 275 is not just an XC on smaller wheels.  It is a complete design aimed at smaller and lighter riders, or simply someone who wants to utilize the smaller 27.5 wheel size.  It is the purest racer, not utilizing plus size tires and optimizing the short 100mm travel suspension forks, or 490 A/C rigid.
 
The SuperB 275 is the lightest of the group, using smaller frame tube sizes and compact design.  The X-Small through Medium frame sizes have a rider weight limit of 175 pounds, with no limit on the size Large and X-Large.
 
The SuperB 275 has proven itself to be a podium machine in the highly competitive NICA race series, with race wins and Top 5 season finishes since it appeared.  If you want the lightest and quickest bike for XC racing, or just plain fun, this is it. 
 
The SuperB 275 can run 27.5 (650B) tires up to 2.4, and uses 100mm suspension or 490 A/C rigid forks.
