Bicycle Mechanics - Action Tec cassette...

...anyone familiar?

This what I'm talking about:

Dig it?

IT seems like solutions to problems that don't really happen and potential problems where the Big S has it covered. All for more $ and less life. Oh weight, you do loose some wait. Andy.

I agree with Andy. Huge cost for a little weight savings and greatly reduced durability. I very seriously doubt their shifting quality claims as Shimano, Campy and SRAM don't go to all of that trouble to create the shaped and formed teeth just for appearance. Give them a try and report your findings.

They're a little late to "invent" shark-finned cogs. ;)

Thanks, guys, for the responses.

Yeah, I'm going to assume the "Big S" is Shimano, I'm not looking at them for this build.

This bike is going to be as US centric as possible. Tires, chain, cables, seat and maybe shifters will be sourced from Europe, everything else will be made here.:thumb:

"Expensive Lightweight Sh*t" is the company motto, so I guess that little weight savings and huge cost makes sense.

Tell me about the reduced life, though. This is heat treated titanium, and the man has reputation for quality work.

Scott, that picture makes me happy.

Looks like it's been around awhile.

I'm hoping for a 19lb CNC beauty. Narrow bars, rigid, flat pedals.

Should be perfect for my daily ride.

I will report back in the spring.:beer:

I used to mechanic on cross country bicycle trips. 3,400 miles in 28 days. We had weight reduction freak start with a new with one of those cassettes and it was worn out at the 2,000 mile point in the trip. I put a Shimano cassette on it at that point and his only comment was it shifted better than the light one had when new. I guess his 17 pound bike went to 17 pounds and few ounces after the change though. Roger

Thank you, Roger.:thumb:

2,000 wouldn't break my heart.

How far did that Shimano go?

Titanium cogs are always far more wear prone than steel, and the smaller the cog, the worse the problem. Shimano limits its Ti cogs on the Dura Ace cassettes to 16T and larger and the Campy Record all-Ti cassette is considered a race-day only item.

All steel cassettes can easily last 10,000 miles or even more if you don't let the chain wear excessively.

My guess would be the Shimano cassette (105) is probably still on the bike 5 years later unless he went weight freaky on me again or upgraded from his 9 speed to 10 speed shifting. I guess the cost was only 12 cents per mile. Roger

Thanks, Hillrider.

Thanks again, Roger.

I can replace the cogs once they wear, this bike's being built for show off purposes anyway.

Bling shall reign.

Are the cogs available individually and are they priced so that three cogs don't cost moer than an entire cassette? If so you can probably keep one cassette going for a fair time by replacing the smaller cogs only. Big cogs are typically used much less and wear longer because more teeth share the load.

Depending on your needs for the bike, you could shave off some weight by running a single chainring with a 70g Paul chain keeper. :thumb:

Reasonable for sure.

$20 for a 12, $89 for a 39.

That's the plan, I'm going shine one up over the winter. :D

And this, for sure:

See you in the spring.
