These seem like exceptional quality & low weight to price ratioLove using these on my road bike! At first they felt slightly stuffer than my previous set, but that has proven to be a plus. Keeping bottles very snug, feeling well made and looking very good. One might need to get used to placing their bottles back, as you have to be rather precise (especially while on the road). Recommended!items as described and for way less than brand name ones. sleek black with no obnoxious corporate logo was just what i was looking for. save your money and get these!Great, lightweight bottle cages. No offending graphics that are visible when a bottle is in them, just matte black. Exactly what I was looking for.These are good. Came with bolts. Fits my Elite brand water bottles nicely.Pro’s-Looks goodLight weight...Con--Only for looks or SLOW rides-Does NOT hold bottles on descends that has some imperfections on the road...1 star lost a bottle cause of it on my unsupported century ride.Final thought...Going back to my aluminum cages because they hold my bottles from bumps on the road.These bottle cages are unbelievably flimsy and my bottles fell out less than 5 minutes into my first ride. Luckily, I was riding alone because I could have caused an accident if someone was riding behind me. I would not recommend these to anyone, and I will be sending them back.These are exactly what you'd expect from a Chinese product. Claimed weight was 17g they came in at 20g and 21g. These are very functional as far as cages go; I've used full sized bottles in them with no rattling so far. They are fairly easy to pull bottles out of and put back in while moving. About $40 less than one name brand cage that would weigh more and you'd need to buy two of.
