|Who built the first cassette hub?||Alex-in-Evanston|

|Just curious. I know Shimano was first to introduce integrated braking/shifting, but it got me thinking who has been first to other meaningful innovations. How about clincher rims? Dual pivot brakes? Threadless headsets?
Again, just curious.

|It's hard to say- it's rumored that there have been more patents awarded to bicycle parts than to anything else, so chances are, when something "new" comes out, it's already been thought of before. But, my list:
I'm going to assume that Dunlop, which invented the pneumatic tire, also invented the rim that it would work on. Seem reasonable?
Dual pivot brakes? I believe Altenburger built the first ones, but they didn't really become popular until Shimano Dura-Ace 7400 series.
Threadless headsets were invented by Dia-Compe/Cane Creek.

|Fairly sure that the first cassette hubs were made by Simplex long long ago (50s?), I saw a pic of them and I think they the mounting hole (on the sprockets) was octagonal.|

|You have to be a little careful how you answer/ask the cassette question. As far as the cassette that we know to day, the one where the cogs slide off and on the freehub body that is part of the rear hub the answer is simple: Shimano. Now the Idea of actually having more than one rear gear and being able to change the gear ratios again it's a question of how you define the question. Do you mean and actual deraileur system (obviously a French word) then it would be either Simplex or Huret (sp?). As far as being able to change the gearing on a bike I think it's on Sheldon Brown's website. You had to actually loosen the rear wheel, slide it in the horzontal droouts, carefully push a lever to coax the chain over then tighten the wheel again. If memeory serves me correctly this was an Italian invention.|

As I said Simplex had a cassette/freehub design long before Shimano designed theirs in the mid 80s. I have seen the photo in one of my magazines lying round here somewhere. The Simplex design used an octagonal hole instead of Shimanos round hole with splines. The Simplex design satisfies all you stated above ie cogs slide off and the freehub body is part of the rear hub.

|Oh, maybe I should've used capitals for "THAT WE KNOW TODAY" and added the word "splined" and split a few more hairs. |
Point is Shimano standardized what we're using today, but may not have invented the very first concept. I guess my point was you have to be pretty careful as to how you ask the question and this simply proves it.
Obviously the Simplex design never made it very far and probably would be included in the THAT WE KNOW TODAY category.

|The original question was fairly simple-'who built the first cassette hub'. Which is what my reply answered.|

|You forget about the Helicomatic hub!!
It was a cassette design that came out before Shimano.
Also, Suntour had the first true shifter/brake combo. The command shifters

|The first pneumatic tires were, of course, not a clincher design. They were more like big@$$ innertubes, and were first used on carriages. Previous to pneumatic tires, carriage wheels used leather tires-the leather was soaked, slipped onto the rim, then dried with heat to shrink to fit the rim. These rims were carved out of wood. The first tires (Dunlop?) fit these types of rims. I would guess that the rim design predates the invention of the tire by at least a century.|

|I saw a Michelin ad that claimed they built the first bicycle tire.|

|The pnuematic tire was first applied to the bicycle by an Irish veterinarian who was trying to give his young son a more comfortable ride on his tricycle. This inventive young doctor's name was Dunlop. Sound familar? Now that comfort and safety could be had in the same package, and that package was getting cheaper as manufacturing methods improved, everyone clamored to ride the bicycle. This 1898 Yale uses a shaft drive to dispense with the dirty chain.
May be technically true, as this was a tricycle, not bicycle.
|CLINCHER ... he asked who made the first CLINCHER.||the other Tim|

|Thomas Jeffery, a bicycle manufacturer from Kenosha, WI (who also built the first 'Rambler' automobile) gets credit for the invention of the clincher bicycle tire and rim.
Dunlop ... sheesh - he invented the sew-up.
