Don't start me! I could quote hundreds, but just for starters:
Fixie - it's fixed wheel!
Campy - it's Campag (except that even Campag have started using it now )
Upgrade - you mean changing a component don't you?
Drafting - sitting on a wheel (with an American spelling!)
Custom - not, as it used to be, a made to measure frame, but just specifying a change to an "off the shelf" bike that people seem to buy instead of building their own
Hydration - do you mean drinking?
I'll be back with some more later I suspect!
And yes, "cockpit" has got to be one of the most ridiculous yet!
Fixie: for fixed gear bicycle is a nickname. That's OK. I prefer 'fixed' as in 'the fixed' as opposed to 'the fixie' but, hell, people call anything a fixed, eh Clazza?
Campy-just WRONG
Upgrade- is NOT the same as replacing a component. I'm damn sure my purse knows the difference.
Drafting- has been drafting my whole riding life. Admittedly it may have been draughting 30 years ago when my dad first explained how to sit on a wheel (usually his) but as it was never written down.. Is it draft (like a first draft?) or draught (like a breeze?) anyway?
Custom- short for customised as opposed to custom-built. Is OK. Not great, but OK
As to
Cockpit, we didn't have one of those. Bars were bars, and had tape on. All that shit on them is new, STIs, computer, lights. Pah. I miss a nice clean set of bars.
