Tune remade or updated their Tune Wasserträger Uni bottlecage. I almost dropped a bottle with one (Uni) on road (pavé) but works perfect for mtb. The weight is 18g.
Now is it totally remade and dropped a lot of weight. Only 9g for the 2.0 version:
What do you think? I will probably buy it and try, so light so hard to resist 😉
