You've got that backwards. The RPMs would obviously be the same, but the surface feet per minute is much higher at the rim.

Just to add my 2¢ to the disc vs. rim brake debate, I personally would always take discs. If you're an all-weather rider, the wet performance is far superior. If you're a trail rider, the better modulation with discs helps a lot.
TRP Spyre/Spyke mechanical calipers are fantastic. I ditched all my hydraulics for them.

ooooops correct you are but the torque required to stop closer to the hub would be higher. Right?
I have the Juicy 3 Hydraulic. seems real nice, a little finger goes a long way.
I'll check the Mechanical Calipers that you mentioned! Thank you!

I'd assume yes, more leverage working against the rotor.

My "plan", is pretty basic BUT I'm hoping for STRONG..

Getting a '18 Bullseye Monster XX for the donor. Going with BBSHD mid. Most all my riding will be on dirt roads. I'm 6'6" and 250lbs.

1. fat tire bike in my size, under $1,000.00..
2. Hydraulic disc..
3. Threaded BB..

I'm excited to start..
