Patrick Moore 'doubts' or 'disagrees with' Jan's tire theories. His fundamental gripe is against absolutism:
"it's just calling these "best" that troubles me" Patrick Moore did not present a quote from Jan Heine as the basis of his argument, and I think that's where his 'disagreement' may be off base. Jan always (in my experience) uses typical qualifiers about his findings and observations. I would bet a dollar that Jan Heine never said "51mm is the best width for 559 rims", or anything else like that. Jan has a preference for wheels that have a similar second moment of inertia: 559xFAT, 584xMEDIUM, 622xNARROW. Patrick Moore just likes what he likes, with no particular interest in a unifying theory: 559xNARROW, 571xNARROW, 622xFAT. Patrick Moore doesn't value speed all that much, preferring instead the feel of riding slow uphill fixed and the feel of riding slow downhill fixed. Jan writes about objective facts, like the fact that a 559xFAT tire can be just as fast as 559xNARROW. Jan also writes about subjective preferences. Since 559xFAT is no slower, he prefers it. It's totally cool that Patrick Moore prefers 559xNARROW. Jan 'publishes' his vigorous approval for Patrick Moore's subjective preferences by commissioning and selling the very tire Patrick Moore prefers. I see no disagreement at all.
