Tri Bike


Triathlon bike for tall guys

Pre-order: In the world of triathlon bikes, if you are over 6’4″ there is simply no bike that will fit. Until now. Clydesdale Bicycles has been listening to the requests from our tall customers and we are finally releasing a triathlon bike for tall guys. This bike is truly designed for tall riders and is full race capable in any type of triathlon or time trial. The titanium frame is light and strong and the geometry will be optimal for Triathlons and Time Trials. Currently this bike is available to pre-order. Please click the “pay deposit link below to place a deposit for one”.  These titanium bikes for big guys are built super tough and come in L, XL, 2XL, 3XL, and 4XL for riders from 5’10” to 7′. The Draft comes with proportional length cranks for optimal pedaling efficiency, and extra wide handlebars to fit broad shoulders. The wheels are custom built right here at our shop in Boulder, Colorado using our own Clydesdale hubs that are rated for riders up to 450lbs! We build these wheels using 36 DT swiss competition double butted spokes per wheel and DT swiss brass pro-lock nipples to keep your wheels true for many miles. Each wheel is precision built by professional wheelbuilders in our shop using high-tech spoke wrenches, wheel building stands, and spoke tension meters.

Available Sizes:  XL, 2XL/3XL/4XL

There are many more factors to building a big and tall bike than most people understand. It is not as simple as just scaling up a “normal” sized frame and calling it good. When you do that, several things happen to the bike. First, the stretched out tubes become less stiff, which results in high speed frame shimmy. This is a scary by-product of a poorly designed bike. Second, the added material makes the bike heavier, especially if the builder tries to solve problem number one with just using bigger heavier tubes. Third, without a fork with a long enough steering tube, the handlebars will be far too low for the tall cyclist causing discomfort in the back, neck, wrists, and arms. Fourth, building a bike for a tall rider with average length cranks will make the rider feel like he’s pedaling a kids bike while sitting up very high. Lennard has developed great frame design concepts to address and solve all of these issues and more, which are all fully applied in the designs of Clydesdale Bikes. A Clydesdale bike designed by Lennard Zinn will be stiff and strong, while remaining lightweight. It will never shimmy at high speeds, and all of the components, including cranks and handlebars, will be proportional to the rider. Fit, performance, comfort, and durability will all be superior on a Lennard Zinn designed bike than a big and tall bike from any other designer out there. We guarantee it.

This truly is a triathlon bike for tall guys, as it’s available in sizes XL through 4XL. We can accommodate riders up to 7’ tall and 450 lbs! In order to ensure you get the most out of your bike, we carefully engineered the proportions of the frame instead of just scaling it up. You get aero handlebars for better aero position, proportional length cranks for better pedaling efficiency, and custom wheels built in our Boulder, CO shop.

High-Quality Materials


We love titanium for our XXXL bike frames, in addition to every other size. Titanium is half the weight of steel and just as strong. Our designers know that larger diameter tubing built with titanium provides more stiffness and strength, better fatigue resistance, and increased power transfer than other metals. It also has amazing compliance and ensures a comfortable ride over all types of terrain. Unlike steel or aluminum, titanium can never corrode, but you can also paint it for a unique look.

In addition to using premium titanium for our frames and top-quality materials for all our other components, we also use spoke tension meters, wheel building stands, and high-tech spoke wrenches when building wheels on this bike for big guys.
