Trekkers are available in either a 20” Rear Wheel. Along with a powder coated Chro- Moly frame, the Trekker series will have some exciting new features. First of course is the adjustable suspension in the frame. By putting the suspension in the frame we were able to shorten up the rear end a bit, and it made a HUGE difference in both handling and traction when compared to the traditional suspension systems we tested. Other features include a Flat Wheel Fold and Adjustable Handlebars. Trekker models will come equipped with our signature Mesh Seat with 4 adjustable angles and 3 height positions.However for those that would prefer a Hardshell Seat with a Ventisit type pad and Neckrest, we can also accommodate you- there is a $75.00 charge for the substitution. X Seam Ranges have also been increased – the Trekker will accommodate riders with X Seams from 34 ¼ (with optional 152 mm crankarms and Z Bars) to 47 ¼” (900mm-1200mm). We can also accommodate even larger X Seams- up to 51? with an optional XL Boom ($50 additional) . Rounding out the features are Avid BB7 Disc Brakes with locking Parking Brake Levers, a High End Forged Crankset with CNC Machined Rings with an Integrated Bottom Bracket, a double Idler System which is as nice as anything any manufacturer makes, and finally a new CNC Machined Rear Derailleur – the Microshift Marvo XE paired with the TS-B10 Microshift Bar End Shifters . Schwalbe Trykers/Marathon Racer Tires are standard.
