Works well, holds 24 oz water on gravel, logging roads, bumpy descents, etc. Doesn't mark the bottle, fairly light weight, totally affordable. Anything more puts you into poseurville.
Cost a bit more but light enough and holds fine ( would be nicer if it had the little plastic gripping buttons near the top like the Aluminum ones do). Holds well anyway haven't lost a bottle yet. Leaves no marks on my bottles. Strong and realistically light weight.
Hold the water bottle fine for road bike use. Yesterday hitting a big dippot hole at 30mph on a downhill section was the 1st real test for holding power. Bottles stayed put. Easy to pull out and replace the bottles. None of my water bottles look showroom new. Don't really care if the cage does or does not mar the bottles. So far, don't notice any new marks on the bottle.
use this cage on my road bike. I do a lot of climbing so I needed the weight savings. The design holds the bottle from bouncing out on the wicked descents, but it also allows for easy out and in when I need a drink.
