Product Description

2017 Yeti Cycles SB4.5 Carbon Eagle Complete Mountain Bike

 

This year, Yeti Cycles joins the crowd of companies offering multiple frame tiers to open up a wider range of pricing for those of us who can't imagine dropping close to five figures on a bicycle. As such, the 2017 SB4.5 Carbon Eagle Complete Mountain Bike benefits from trickle-down technology to bring a fast, race ready frame with top-tier components into slightly more attainable territory. The carbon construction is still top notch, and is a shining example of just how advanced carbon construction methods have become. It's just a little bit heavier than the high-grade Turq model, which drops the price considerably for the sacrifice of 300 claimed grams of added weight, which, in real world terms, is roughly equivalent to a small mug of hot cocoa.

Yeti says that the SB4.5 has a stiffer pedaling platform than most of its other bikes. While we don't have numbers to verify this claim, it's definitely a responsive go-getter when the going gets grindy, and the inclusion of a Boost 148mm rear axle and the surprisingly climb-happy X01 Eagle drivetrain is certainly at least partially responsible for the bike's eagerness on climbs. Coupled with the innate aggression of 29in wheels and the stiff, collet-style hardware, the boosted rear triangle certainly feels every bit as stiff as any of Yeti's other models.

The frame's aggressive speed is not to be outdone by its slack front end and surprisingly capable Switch Infinity suspension, though. Its 67.4-degree head tube is one of the slackest we've seen on an XC-leaning 29er, and it makes for a boost of confidence while picking lines across terrain that would make a more typical 70-71 degree head tube stumble. The Switch Infinity suspension is equally confidence-inspiring, and its linear travel hits the sweet spot of anti-squat to keep pedaling sharp across rocky climbs. It also erases the momentary harshness that its predecessor, the Switch Link design, would display when pushed to the absolute limit.

Of course, most riders didn't experience that dead spot on the Switch Link, but the SB4.5 isn't for most riders. It's for the all-mountain racer who demands that their machine flattens big hits with the same tenacity that it cleans long climbs. In our experience, the SB4.5's Switch Infinity suspension isn't quite as soft off the top as the 5.5 and it finds the bottom when we overshoot a landing. That said, the steeper head tube produces sharper handling and rewards technique while picking lines, making the SB4.5 more fun if you're value finesse over just bombing terrain.
