The Big Half Deal (B.H.D.). This is a special, larger diameter version of the 85mm-wide carbon Big Deal rim. With a 27.5-inch size, it's smack-dab-half-way between a 26" wheel and a 29" wheel. If you have a new-fangled 27.5" fat bike, this is the performance rim choice.

• Do not use tire levers
• Can be set up as tubeless without the use of tubeless tape with the use of HED's Tubeless spoke head washers
