We have 3 Slowtwitchers who are all very similar in their Pad X/Y numbers (675mm/500mm), with Forum User Names: duckies, callin’ and kcb203. Here are your bikes.

This new Pad XY chart should make deciding on riding Starky’s Ordu OMP LTD series bike much easier for fitters, salesmen and end users.

Are you 5’4″ to 5’8″? Looking for a tri bike? Here are Slowtwitchers in that height range who have similar Pad XY measures. Here are some bikes they can ride.

Everybody is different, right? Yes, in a micro sense. But in the macro world it’s truer to say everybody is the same, and the pros demonstrate this.

Everybody’s talking about Pad X and Y, or Pad Stack and Reach, in regard to bike fit and selection. What is it? How do you measure it? How is it used?

There is hope for Aliens, and by these I mean the freaks of nature who contort into pretzels to ride long and low positions. Aliens, here are your tri bikes.

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.

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.

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.
