10 mph? Any faster and the naked (no fender) tires would have soaked me good. I also rode faster on the non-flooded parts with wet wheels & it was slightly diminished from dry, but i could still make the back tire skid.

I think the trick is to mentally extend your stopping distance based on conditions.

I've been riding SA drums since the early 80's. They work better than rim brakes including v-brakes and the newer 90mm SA hub has braking modulation and power comparable to BB7s. The dyno/drum ends up weighing the same as a dyno/disc set-up once the weight of a disc fork is included.

From a quick search, here's a guy who had to go to 4 bike shops to find a guy who had the right tool to remove his drum brake -

This is silly, It takes a little longer to line up the torque arm into the bracket in the front and rear. No different than a coaster brake, no big deal for anyone with simple mechanical abilities....

As for bluing rotors, I've done it every year when MTB'ing in Jamaica. Some of the steepest trail grades are on the island and they are long. I can't imagine a road that could blue rotors because they're graded for cars.

i was surprised to see how many riders in the recent cross crusade series were sporting sturmey archer drum brakes on their lugged steel steeds.

:rolleyes:

Sure, I'm sure 3 different shops who could figure it out all had the problem that they didn't have any mechanics there! (lol, right)

Are you suggesting it takes special tools and skills? Just because you haven't ever used it doesn't prove it sucks.

You might try actually reading the post I posted.

I went to a bike store to have them remove a freewheel, nobody there had ever worked on one. I had to find to remover on their bench and show them how to do it. Does that make freewheel sucky too?

I have the very drum you've cited, the solution is explained in the only reply to your cited thread. The Akai drum threads on, it's not rocket science and you don't remove the drum to fix a flat. Some 19 year old minimum wage wrench can't figure it out, you never rode or worked on a drum, so drums suck.

Makes perfect sense!

Well, since it's "no big deal for anyone with simple mechanical abilities", let's go through the possibilities:
1. You were really drunk and wandered into a walgreens, thinking it was a bike shop
2. You fell asleep watching tv and got a tv episode confused with a half awake dream
3.
The "bike shop" you went into is a front for a money laundering or drug dealing organization...for your own safety, I highly suggest you go somewhere else for bike repairs!
