Mon Jul 11 2016: 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.

Mon Jul 11 2016: 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.

Mon Jul 04 2016: 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.

Tue Jun 28 2016: 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?

Tue Jun 21 2016: 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.

Mon Jun 20 2016: 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.

Thu Jun 16 2016: 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.

Wed Jun 15 2016: 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?

Sat Jun 11 2016: 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.

Mon Jun 06 2016: 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.

Mon Mar 28 2016: 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.

Fri Feb 19 2016: 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?

Thu Mar 07 2013: Why are bike companies trying to sell you bikes marketed for cobblestones and potholes? They're still testing out all but the obvious narratives for new road geometries that better fit many ...

Tue Mar 05 2013: In our celebration of the Stacktennial, let us not ignore the ladies. The problem is, of course, the constraints placed on bike design if you mandate that the bike be built with 700c wheels.

Sun Mar 03 2013: It's been 10 years since the metrics Stack and Reach were first described. February marked a decade since these terms first made it into print, at least according to my recollection.

Mon Feb 04 2013: Top pro triathlete Maik Twelsiek decided to try something which, for pros, is novel and rare: He got fit first, found the equipment that worked for him, before seeking a contract. Here's how it went.

Mon Dec 20 2010: Bicycles are constructs of assemblies. Of course you know this already! But I'm talking strictly about how bikes fit. The notion that a frame alone determines fit is entirely wrong.

Mon Dec 20 2010: The defining fit characteristics of bikes are no longer solely contained in the frame. Or even the aerobars. Today's superbikes focus on the sins of the stem and anything round sitting above the ...

Tue Nov 18 2008: It's late November. Don't you love the change of seasons? Depending where you are, the greens are turning to yellow, and the yellows red. But that is not the change to which I refer.

Mon Jun 23 2008: The F.I.S.T. tri bike geometry calculator is open for beta testing. Your fitter plunks numbers into our online engine and, poof, your custom bike geometry!

Wed Feb 19 2003: Earlier in the decade I wrote an article on how bikes are sized, and the gist was that we ought to be looking at bikes from the point of view of head tubes and top tubes, and that's it. -- no more ...

Wed Feb 19 2003: In the final chapter of our stack and reach primer, we compare stack and reach with other ways of remaking sizing nomenclature.
