Triathlon bike for tall guys

In the world of triathlon bikes, if you are over 6’4″ there is simply no bike that will fit. Until now. We at Clydesdale Bicycles have listened to the requests from our tall customers and we are now making 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. This bike is available with two main component packages; Shimano 105 mechanical shifting and Sram eTAP AXS electronic shifting. We have multiple wheel options depending on your needs. Please request a quote so we can send you an itemized price list for either option.  These titanium bikes for big guys are built super tough and come in 2XL, 3XL, and 4XL for riders from 6’4″ to 7’2″.

Available Sizes: 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 XXL through 4XL. We can accommodate riders up to 7’2″ tall! 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, 180mm cranks for better pedaling efficiency without sacrificing the aero position, and custom wheels built in our Boulder, CO shop. You can also choose to upgrade to aero wheels for racing. 

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.
