Hey tall mountain bikers. The new Zinn full suspension mountain bikes are here to revolutionize trail riding for big and tall riders. The B.I.G. series is available in several different suspension options. The six is a 6-inch travel enduro bike with super plush suspension and excellent trail riding geometry. This bike climbs and descends like a dream. The five is a 5-inch travel trail bike that is fast and nimble and perfect for any type of riding, from cross country to enduro. The four is a 4-inch travel bike aimed towards the cross country side of the spectrum. It can handle any trail you can find, with ease. All models are available in XXL and XXXL sizes, and are compatible with Zinn custom length cranks. These drawings are of the XXL size, but we can provide XXXL geometry if you send us an email. http://ow.ly/i/8NM0z http://ow.ly/i/8NM0C http://ow.ly/i/8NM0G
