So I'm looking for gun metal colored components. Quill stems, seatposts, wheels. Any suggestions.

Thanks.

the 3T motus stem is available in a gunmetal finish; some of their other stems might be also.

Yes, definitely look into the Motus. I have one and love it as it has a removable faceplate.

Also, you might want to look for Shimano 600 (6400) components. They are geared, but you can likely get parts to work for you (e.g. cranks, brakes, brake levers).

ITM 400T quill stem has a gunmetal finish.

IRO has a gunmetal finish hub set

njsframes.blogspot.com has some gunmetal components every once in awhile. i have nitto n123s in a gunmetal finish

Yeah, I had a 3TTT gun metal quill stem (sold on ebay several months ago). Still have the gun metal bars that I use.

cinelli grammo is a Ti quill stem.
some recent campy group (centaur? chorus?) came with a grey metallic option.
current ultegra SL has a gunmetal finish.
gran compe hubs are gunmetal anodized.
apparently the 144bcd sugino zen comes anodized grey but i haven't seen one in person.

i thought you guys all hated guns, but now you want your bikes to look "gun metal"??? what gives... posers.

dura ace track cranks are probably not exactly "gunmetal" as they are not dark enough but they have this silky smooth-ish sheen look yet still are polished, and not raw metal looking. it's hard to describe but you could work it in.

The Nitto RB-018 heat-treated bars as above are gunmetal and look great.

given the right material, you could always find a place that will parkerize your parts. that isnt quite the traditional "gun metal" color, but it would definitely look like military firearms, reduce reflection, and resist corrosion like a champ. i have also always wondered about bluing parts... what a notion!

mellow johnny's(austin, tx) has a display case with a bunch of nitto stuff in gunmetal. call them up and see if they can ship it out. google them for there number.
