Bontrager - pronounced BON-TRA (little "a" sound as in "apple")-GRR
Giro - pronounced JEER-OH
Jamis - pronounced JAY-MUS
Motobecane - pronounced MOW-TOW-BEH-KHAN
SRAM - pronounced just as it looks, one syllable, SRAM (like "scram" without the "c") *Fun note: The name is actually a conglomeration of the three founders' names: Scott, Ray and sAM.
Thule - pronounced TOO-LEE by most (and most accepted), but technically, if you want to get down to the linguistics side of things, it should be pronounced TOO-LUH. I'd go with too-lee unless you want people to think you're a snob.
Truvativ - pronounced TRUE-VAY-TIVE (not true-vuh-tive, which is quite commonly heard) Supposedly, it comes from the the two words Truly Innovative being combined.
I'm sure there are plenty more that aren't listed here, so if you have one or more that you've heard mispronounced or that you think we should know, please feel free to chime in. Hope you're enjoying a very happy Friday!
