We are using 'A' and 'B'

People are interested in the inflated measurements of the tires they put on their bikes. I have measured some of the Schwalbe tires that we have on bikes in our fleet. The tires were inflated to their normal running pressure.

Measurements are in millimeters, height is from the edge of the rim. ETRTO size is in parenthesis.

The diagram is from the excellent Schwalbe North America technical pages.

Please Help
Our list is growing but it needs more. Please contribute the measurement of your own Schwalbe bicycle tire in a comment. Once we get enough data to be meaningful I will add a column to our online tire table.

British cycling journalist Carlton Reed has a good article about saddles and medical problems on the Quickrelease.tv blog.
If you skim articles and remember the highlights I can save you some trouble. Carlton quotes Dr Irwin Goldstein’s 1997 Bicycling Magazine article:

“Men should never ride bicycles…Riding should be banned and outlawed. It’s the most irrational form of exercise I could ever bring to discussion.”

We have a few special Swallow saddles to sell. These are part limited run of green Swallow Classics made to support the Bicycle Film Festival. The Swallow is not usually available in this color. This Swallow Classic has chrome steel rails. There is no stitching along the skirt. One-hundred of these saddles have been made and they each have a unique serial number.

We will be asking $260 for these saddles. They are still listed on the Brooks website for $240 so if you want one you should probably check there first.

We are also getting a couple of other missing saddles: B.67s in honey and B.68s in black. They all should get here later next week.

edit 8/13: these saddles arrived today

Customer Steve Courmanopoulos shares a little insight into the Brooks ethos in his blog piece Technophrenia.
(FYI: Steve pictures a Swallow but his inspiration is a B.17ti)

This Monday I put together an order for Schwalbe North America. I looked at stock on the nice Ultremo tires. I had bought 10 in May and we still had six. I think ‘”Four tires in three months? The remaining six should last till the next order, at least.”

On Tuesday two customers bought all six of the remaining Ultremos.

We can run low on stock because I don’t plan well. We can run out of stock because the suppliers can’t supply. But sometimes we get surprised.

I was able to add the Ultremos to the order but for a few days they will be “out-of-stock”
