What you’re looking at is a set [2] of carbon style [in other words looks like carbon fiber but is NOT] aluminum cages by IBERA. These would be great for road, mountain bike [MTB] or gravel bike/commuter applications not to mention recumbent, comfort, commuter, cross etc. Your call on all of the above. Again I say these are NOT carbon, they just look exactly like carbon! Note the insides of the cages which show some wear and thus the carbon weave design has rubbed off. Scroll through all of the many images! These are in great physical condition with the only cosmetic issues being on the inside [which is not visible when bidons/bottles are loaded]. These would look rad on just about any color bike with my top picks being black, red, gray, slate, etc. Fortunately there’s no carbon-style pricing here so I’m gonna let this set of Ibera cages go for the low low KSL price of $19.99! Thanks for checking out these Ibera Bottle/Bidon Cages & for shopping with me here on KSL today and have yourself a great and a blessed day! :-) Cash [only] accepted. Text is best. FCFS.
