How about 11-34 will this work on shimano a 7 speed 14-28 freewheel as well

I replaced a shimano 14-28..with this drift maniac 11-28..it works well on my lectric xp. I don't know if a 11-34 will fit without any adjustments. SR

Is this 34mm thread ?

hub freewheel thread diameter:34mm for 7 speed freewheel 11-28t

Is this a freewheel or a cassette? does drift maniac actually make any freewheels or are they all really cassettes?

I don't know if Drift Maniac actually makes anything or if they just sell what other people make, but it's an actual freewheel cluster. It uses a standard 12 spline freewheel wrench and comes off as a single unit rather than a stack of individual cogs.

Will it fit a Radcity 4 11/34? I know nothing about replacing a sprocket set.

I have a 2017 RadCity and this fit. Worked real well for about 2 months until the smallest gear fell apart. I can still use gears 1-6, 7 just has a big chunk missing.
