Got this fat bike off of FB marketplace.
Came with a receipt from a bike shop for all new rotors, pads, cables and levers.
Took it on its maiden voyage and the rear break was metal to metal.
Tonight I took it apart and found the rear inner pad installed metal side towards the rotor.
All fixed now.
I plan to make this bike my main bike besides for mountain biking.
Can someone steer me in a direction as to where to buy headset bearings and bottom brackets for this?
I believe it's a dynacraft krusher

Frame BB width is , most likely, 120mm.
it is, almost assuredly, a square taper spindle.
the thread rate, unless dynacraft did something rewally stupid, is 1.37"x 24tpi.

you will find the bike heavy, slow, and prone to problems, if ridden frequently.
brake pads can, typically, be removed without separating the caliper bodies.

good luck.

What do you mean prone to problems?
I bought a single speed to get away from problems.
The heavy and slow is not a problem for me.
Most of my riding is solo or with wife and kids.
If I'm on a geared bike riding with them it's to easy for me to out pace them
Thanks for info. You are correct that it's square tapered. If that refers to the part of the crank you can see on the non drive side

The square axle / spindle you can see is actualy part of the BB on these, with the crank having a corresponding square hole, but yes.
