The Lightweight Edelhelfer (German for “Precious Helper”) water bottle cage tips the scales at a claimed 18 grams.
The crisscrossed retention loops mimic the carbon spokes on Lightweights’ wheels. It comes with two small alloy screws to hold the “Reserve Tank”, as they’re calling it, to your bike. Now, matching your handlebar tape, tires and kit will no longer suffice for a complete look. Your cage must match your wheels.
UPDATE: Price is around 65€, which may vary slightly depending on VAT and shipping.
