Hi, everyone. New here (lurk a bit) and didn't know if I should just start posting or go somewhere to formally introduce my pretty little ass. But.....

I have a Brentwood with 7 speed drivetrain and want to 9 speed the thing. Is the spacing still gonna be 135?

Also, the rear wheel just bolts on. Any problems using a wheel with quick release?

Thanks

Have you tried measuring it?

I think that model has derailleurs (not internal gears) so if it's new-ish and 7 speed, it is probably 135 spacing. The only frames (atb and comfort/cruiser type) that don't have 135 spacing are 6-speed (130mm) kids type bikes or bikes with internal gears (126mm or narrower).
