| The Zinn B.I.G. 29er is a revelation in the world of full suspension mountain bikes for tall riders. With updated geometry and rear suspension, this Zinn bike is the ultimate mountain bike for big and tall riders. It’s available in four-inch travel, five-inch travel or six-inch travel, and it uses a durable 4-bar suspension design that is plush and reliable. When designing the perfect big and tall bike for all-mountain riders, several things are important. First, the bike must fit well with the handlebars high enough for the rider to be comfortable and in good control. It also makes sense that a big bike should have big wheels. The 29 inch wheels of the B.I.G. help to get the bars up higher, and when combined with our long and beefy head tube, we can get the bars up enough to fit a 6’10” guy comfortably on our XXXL size. The super beefy tapered head tube and down tube makes this one of the stiffest frames in the world, and you will find it to be very controllable in the most technical terrain. One of the most important aspects of bike fit is the crank length. It doesn’t make sense for a 6’10” rider to be riding on the same length cranks as a 5’10” one. The B.I.G. is designed to accommodate up to 210mm cranks. Click here for more info on Zinn Custom Cranks.
Finally, the bike needs to be strong enough to handle the steepest technical trail rides and stiff enough to hold steady under a very large person. We press-form our massive down tube to provide the stiffness and strength to take the abuse a 275-pounder can dish out all over the mountain. This Zinn mountain bike uses a 12x142mm rear through axle for ultimate strength and stiffness. Also available for use with 29+ tires (29″x3.00″) . The B.I.G. comes in sizes XXL-PLUS(24”) and XXXL(26”) sizes.
