The 650B bikes are some of the sweetest out there –most of the benefits of the giant 29ers with all the nimbleness you want from your old 26-incher. Schwalbe produced the Racing Ralph MTB Tire for members of the top-secret 650B club, and it’s a beauty. An excellent all-around tread pattern, light weight, and easy rolling design make this tire ready for all-day off-road adventures.

• Sharktooth-style U-blocks grip in all terrain, and love being leaned into
  
• Extremely low rolling resistance saves energy to make your day more enjoyable
  
• Open tread design self-cleans to avoid mud buildup
