Anyone using this product?

Saw it over at Hi Tech Bike's site. They replace the alloy clamps for yor Ergo levers and are reported to save you 18 grams...

Be the bike.

Not sure that I would trust that little carbon ring while cranking on the hoods on a climb.

I think carbon isn't as fit for small parts like that as it is big parts like tubes.

The future I see is integration of parts, instead of a bunch of bolted together parts we have now. The Cinelli Ram is a good start. I also see that there are seatpost/saddle integrated parts, too.

What's the ultimate? How about a complete frame with integrated seatpost and saddle. Maybe you just add a neoprene cover over a carbon shell. Of course, you'll have to get the sizing perfect from the start. The bottle cages could be integrated, too.

How about integrated stem, handlbars, and shifter/levers?

We already have what are effectively integrated wheels, the ADA, but I suppose tri-spokes and discs are, too.

Brake calipers could be integral to the frame and fork.

Pedals could be integal to the cranks, and the left crank could be integral to the bb spindle and rings.

This could cut down a lot of weight, be stronger, but would very little room for adjustment. Whaddya think?

... we use the term carbon fiber in the same way we use steel, aluminium or titanium... failing to take into account the specific form (alloy) of the material... meaning, there's got to be more than one form for CF (either the type of cloth, type of matrix or hybridization (aramid fibers embedded within the matrix... perhaps even alloys)).

Again, the beauty of carbon fiber may be in the ability to design it's layout for a specific function. Indeed, in some applications (and for given stresses), carbon fiber could be superior. In model aeronautics, reinforced nylon and carbon fiber has been used for years in motor mounts... I even experimented with a simple matrix in my model building days (took old panty hose cut into strips... then saturated with glues (either an ambroid type, epoxy or even cyanoacrylates) to make extremely strong yet extremely lightweight joints 'tween certain wooden components. In some applications, composite fixing bolts are used for seemingly paradoxical reasons... the strength to hold an engine to it's mount yet with the ability to be sheared to save said motor from damage in a crash.

Markets drive some forms of innovation... with many good ideas falling by the wayside simply for lack of said markets or prohibative costs... or worse yet... a major player in a particular market, protecting itself by buying out the little guy... then burying the product (you didn't hear me say Shimano).

One thing is certain... with respect to cycling equipment, 2004 promises to be biggest year yet for folks in search of a high fiber diet.
