What is this?
 

Whilst searching for stainless steel bottle cages for the Treviso, I happened upon this image:

I see "Interdrive" but can't find info on that. Bike looks to be an 80's Orbea, guessing by the -ea ending on the seat tube.

No info. on that Italian Cycling Journal blog.

Anyone have any information/history on this crankset?


And while you're here, should I get the Elite Ciussi bottle cages or the Velo-orange ones?

One more thing, please. My rear tubular had a sidewall blowout a mile into a group ride. (Challenge Strada) I have another I bought as a spare but I'm looking at the Vittoria Pave EVO as a stronger replacement. Is that overkill? Is the EVO CX good tough enough? I've searched and searched but nothing on the Pave and lots of people say the EVO CX is durable and an equal number say it is not.

Check out the crankarm on this bike:

That looks like it would hurt.

It looks so heavy. I want some of those Campagnolo disc wheels.

Looks like they home-butchered a Cook Bros crank. Don't know why though.

Bent cranks are these-

Freakin Cool Cranks.

@ the OP, I love my Vittoria EVO CX tires...just bear in mind they are high end tires with High TPI casings, no added puncture protection and simply have less rubber on them than a standard tire. Folks who are accustomed to Conti Gatorskins and Panaracer Pasela TG's are likely gonna say those Vittoria tires are flat prone and wear out quickly. Just bear in mind its all relative.

I've had mine for 2 seasons and they've got some miles left but they are starting to wear out and I'll likely replace them in the spring. When I first put them on I was getting a lot of pinch flats but it was only because I wasn't in the habit of pumping them up to 110psi and checking the pressure regularly. Once I started doing that the flats disappeared. User Error.

Say what you like about the durability but I'll say this much about those tires....show me a person who thinks they don't offer a great ride and I'll show you a person who doesn't know what a great riding tire feels like.

I think it's an effort to try to extend the powerstroke through those springs for more efficiency....but then that thing looks really fugly....and most likely heavy too....but then these might work better than all those Delta type Aero brakes from the 80's...

"the idea is the same as on the Shimano Biopace cranks"

Think I'll stick with Biopace. Looks like something out of Wallace and Grommit.

Thanks. Just what I needed to hear. People say Michelin Pro Race 3's aren't durable but I rode all over the 9 county area for three years on them before they wore out.

To avoid the question and add another option, I like the Nitto R cage.

Nitto R's are okay ;)

I was going to put them on my new bike, but they were heavier than the Minura Ti cages that were on there :eek:

The thing is, you can't maintain much leg force on the crank arms as they go through top or bottom dead center. So unless the crank arm has some momentum to help carry it through, the spring will simply release by pushing back on the foot. In other words, it won't increase the length of the power stroke at all. So as the foot moves across top or bottom dead center you still won't get any improvement.
