Tailfin’s Rear Systems: The Mounting Options Explained

Estimated reading time: 5 minutes

A complete guide to the mounting options of your Pannier Rack, CargoPack (formerly AeroPack) and SpeedPack

Note: This guide references our CargoPack, formerly known as the AeroPack – part of our modular Rear Systems

Introducing choice should be a positive but we are aware that it can make things a little more confusing when it comes to deciding exactly which approach is right for you. To help work out what works best for you we have produced this guide to look at the pros and cons of each approach.

Three Ways to Mount your Pannier Rack, CargoPack or SpeedPack

1. Axle mounting

(Axle + Fast Release Dropouts)

This offers the strongest mounting option and works for the majority of bikes – even those without rack mounts. By attaching your Tailfin system to the axle, the stresses on your frame are almost eliminated, making this the safest option for use with light and high-end carbon bikes. It is the mounting approach we recommend above all others.

2. Frame Mounting with Adapters

(Frame Mount Adaptors + Fast Release Dropouts)

As with direct frame mounting, the one key drawback of using the adapter approach is that your frame needs to have the relevant rack mounting points in order to fit the adapters and be rated to carry racks (not just mudguards/fenders).

You must check with your frame manufacturer whether the mounting points on the frame are rated to carry a load or if they are just intended to be used with mudguards/fenders. If they are only suited to mudguards/fenders, they should not be used for rack mounting.

3. Direct Frame Mounting

(Direct Mount kit)

The semi-permanent mounting that gives this added security could also be seen as being the main downside to direct frame mounting, as you cannot quickly remove the rack when it is no longer required on your bike. It also requires your frame to have mounting points that enable it to fit racks (not just mudguards/fenders). No eyelets, no direct frame mounting, sorry!

As with the Frame Mount Adaptors, the other vitally important aspect to check with your frame manufacturer is whether the mounting points on the frame are rated to carry a load or if they are just intended to be used with mudguards/fenders. If they are only suited to mudguards/fenders, they should not be used for rack mounting.
