Review on 🔧 XLAB Delta Sonic ML Bottle Holder - Black, Universal Size by Adewole Sherman

It's a clean beautiful design and if you add a cage bag you can carry spares along with the bottle. It feels very solid and is part of the bike, unlike rail mounts or previous iterations of seatpost mounts that spring a lot. Unfortunately, the screw that holds the rail to the seat post clamp sheared off after only 6 months. I'm a salty sweater and I sweat a lot, but it happened really quickly. I would recommend that you replace the M5 bolt with a quality blue loc site stainless steel replacement when reassembling.
