A Pad Y/X of 630mm/505mm is a typical position for somebody between 6’0″ and 6’3″ who rides pretty steep, with a fair bit of armrest elevation drop from the saddle.

Top tri brands make tri bikes that fit marvelously. Today’s tri bikes are very good, but they’re very uniform, and the lack of variant geometries leaves many riders out.
The first in a series, prescribing bikes to match the profiles of various kinds of riders. The rider here is 5’9″, rides pretty steep, pretty aggressive. What’s his bike?
Frame metrics are real, they matter, they tell the truth – stack and reach tell the truth – but they don’t tell the entire truth about fit.
Steering torque and center-of-gravity have become competing imperatives in bike geometry, with front-center caught in the middle. What’s caused this tension? Deep front wheels.
First published 16 years ago, this article by John Cobb on wheel (steering) torque is even more topical today, with the increased use of deep wheels since its first publication.
What you’re reading today is the intro to a series of installments matching you to your optimal tri bike. I’ll identify you, and then “prescribe” the bike(s) that work best.
“I cannot understand why all bike fits aren’t more like this.” – Comment from a subject after a Complete Bike Solution exercise at a Slowtwitch Road Show.
Felt sits second among tri bike brands when Slowtwitchers are asked what they intend to buy next. How do you decide, precisely, what size and config for your IA?
Rider needs a long and low geometry. It was the Soup Nazi answer for this guy: No bike for you! Then I remembered the TriRig Alpha series bars, and its online calculator.
A superbike complete bike solver can be built in half a day. Here’s the first one I built, and how I built it. Why don’t all superbike makers have one?
With $58,825 raised so far, let’s make a great push to wrap up the 7th annual Rappstar Charity Challenge for World Bicycle Relief.
