About the SB4.5

A Classic XC Bike

• Cruises through climbs and descents confidently
• 114mm of grippy, poppy rear travel to get through the rough
• Switch Infinity suspension provides unmatched efficiency and traction
• Trail geometry is nimble, and still capable on the descent
• Older version of Yeti’s SB115

Based around Yeti’s renowned suspension platform, the SB4.5 is an ultra-capable trail bike. It’s less modern than the SB100 and the 115, but rides nearly as well. Perform day-in and day-out, on the trail and the race course.
