It would be a nice idea to send it to FrictionFacts for a review.


I afraid people will think this is an advertising. I just a designer :noidea: , I really want to know what is mostly roadbike rider want.
Because upper wheel axis also locate the cage dead point, one bolt two functions to save the weight. Final version will fit 11-28.


it says that the Shimano 9000 series is ready to ship? i like the one arm SRAM version with sturdy top pulley. i would like to try one out...but costs still seem a bit high. very close to Brenner.

Thank you a lot, it is not difficult for me. It is already have new perk on indiegogo.
I really like campag design, My first road bike use VELOCE 10S with old RECORD rear derailleur. When I started design the oversized pulley I afraid it will destroy campag's tbeautiful.

no love for Berner? That's what some of the pro's riding in TT's would use.

berner very hard to get i thought.

edit
apparently not too hard (website updated since i last looked) but quite expensive. as in 500 euro

another option is carbon dry from japan but similarly expensive as berner.

I've got a UCB on my DA9070. Works very well, including 32T. Carbon cage with Ti pulleys and ceramic weighs the same as the stock cage, so it's not a weenie move - but it's much nicer than having to use an Ultegra GS6870 RD in the mountains...

Is this world's fastest and lightest oversized rear derailleur cage currently being produced and available for sale? The references in the original topic show it being distributed only to original Indiegogo contributors over the holidays. However, it doesn't reference future production or where further information can be found.

I'm interested specifically in the Sram E-tap version and would like to give one a try if I can find where too buy.

I appreciate any update.

My experience with the 15 the top and bottom pulley systems are that the pulley rubs the largest cog of the cadsette, negating any friction benefits gained. I even used longer be screw to no effect. Ended up putting back the stock dura ace cage and happy again.
