In the Bike Shop: Trek’s Precision Fit Socket Technology

Wanna get a bike shop mechanic to do a spit take, say, “hey the new Trek Madone has got precision fit socket technology!” Some may just spit their coffee right out their nose, laugh uproariously, shake their head, or remind you of that year the Madones used Klein’s bottom cup design on their forks and how that didn’t work.

Same thing when talking to a guy like Bill Davidson who can prove he’s seen it all before in the industry, by showing me a 1985 Magic Motorcycle external bearing bottom bracket design – referred to here in an FSA article from 2004. “But hey, you can just press those sockets in by hand, according to Zinn! “Righto!” according to the mechanics.

All for technology here at the bike hugger, we’re also skeptical of precision anything when it comes to headsets and bottom brackets. Well, at least the old-school mechanics we know are. Whom btw, also didn’t trust Mavic’s Heliums or the Krysiums, which revolutionized the built-wheel market.

A topic for another day is square v. compact frame design. As I said to our friends at Novara yesterday, “taking a 1/2 pound off a square bike would’ve been an even more impressive achievement.”
