RB means 'rust buster'; they, or at least the side plates, are hot
dip galvanized, ot prevent rust.

I use a similar one on my IGH bike, they work fine, and are cheap. I
even use one on my beater, which has an eight speed free hub.

Rely on just one chain only to keep a little rescue pod from crashing into a

Heck with that. Check out the video "Super Fast!!" that comes up at the
end.

But where is the flashy accident?!

I wonder what rpm they're pedaling at? The guy standing moves about
whilst the guys are spinning and therefore you know that video wasn't
just sped up.


Switch to 0.25 speed; watch and count. Could be close to 250 peak.

If both pedals aren't subrmerged at the same time, it's not
torrential.

I don't have a drain hole in my BB, so if I get into water that deep, I have to pull the crank and shake out the water. On a stupid whim, I rode a fully submerged MUP that had been inundated by the Willamette River. I was almost swimming in one place. I had to drop the fork and dry out the headset.

Some of the street lakes aren't, but the inch-an-hour type rainfall is a rarity. This is not NC.

I timed Captain Dan Henry at 200 rpm on rollers when he was well into
his 70s. (Old timers may remember him. He did roller riding
demonstrations in which he would disrobe down to his shorts. This was
back before "clipless" pedals, and he didn't use toeclips.)

And I timed my grandson at 175 rpm on a 12" wheel bike back when he was
four years old.

Got caught in a storm a few weeks ago. I needed to replace my tires so
I was doing that while in the basement watching tv. When I pulled the
rear tire off it splashed water all over the carpet. The front one had
some water as well. Never had that before...

I normally won't do deep water on a road. I'd be too worried about
unseen holes, etc. I've crossed streams with a mountain bike, but never
more than about 6" deep, IIRC.

On one tour (Ireland, the wettest experience of my cycling life) we had
no alternative but to ride a flooded portion of road. The water was
maybe 6" deep, not quite up to our bottom brackets. I sort of
ratchet-pedaled across, keeping my feet dry. My wife and daughter just
cranked through it and laughed about it.

Try bear grease, that'll teach 'em.
