Review on 🚴 Enhanced Biking Performance with Speedfil A2 and Z4+ Aerobundle Water Bottle System: Hands-Free BTA Hydration with Refill Port by Carlos Chan

After installing this system on my bike it was great. My advice: don't tighten the zip ties until you're sure they're where you want them! I had to use other cable ties because I kept reinstalling them. The refill flap is a little tight, but works perfectly. If you use Nuun tabs, you have to split them in half or they won't fall out of the hole. This is a bit cumbersome in racing, but by no means a hindrance. Computer mount is the best. My numbers are right in front of my face.
