Seat-post bottle-cage adapter

The Hollywood Racks TM holder clamps to a seat post and carries two standard bottle cages. It is machined from 7050 aluminium alloy for high strength and low weight. The silver finish resists corrosion during regular road or trail use. Cyclists gain extra hydration capacity without frame-mounted bosses.

Riders lacking frame cage mounts

This adapter suits bicycles that have no bottle-cage braze-ons, including many folding bikes and speciality frames. It also helps riders who want a second pair of cages for longer distances. Cyclists who already have two or more frame-mounted cage positions do not need this accessory. Riders who prefer a single-bottle setup should look at simpler single-cage clamps.

7050 aluminium construction

The holder is made from 7050 aluminium alloy, a high-strength grade that resists distortion and fracture after hard impacts. This material choice keeps the clamp light while maintaining a secure grip on the seat post. The alloy also withstands repeated vibration on rough surfaces. Buyers who need a different material or a specific clamp diameter must verify compatibility before purchase.

Questions about this item

What aluminium alloy is the TM double bottle cage holder made from?

The holder is machined from 7050 aluminium alloy, chosen for high strength and low weight so it resists distortion after hard impacts.

How does the holder attach to a bike that has no bottle-cage bosses?

It clamps around the seat post, letting you add two cage mounts to frames such as folding or special-design bikes that lack threaded inserts.

Which way should the clamp face when bolting it to the seat post?

Position the clamp so the two cage-mount tabs point rearward; tightening it backward is the common mistake that blocks bottle access.
