Scicon Phantom 230 seat pack review

Scicon’s diminutive pack lets you carry the basics in style

Cycling Weekly Verdict

The tiny Scicon Phantom 230 has a clever fixing system and sits unobtrusively on the saddle rails. Its small size means that there's only room to carry the basics, although the included tyre levers are a useful added feature

    Too small for much more than a tube

Scicon has moved away from its focus on luggage for carrying bikes around recently, making a splash with its high-end sunnies and £225 bibshorts. But it still sells bike travel bags, alongside a range of different sized saddle bags. The Scicon Phantom 230 is one of its smallest.

Designed to clamp to your saddle rails, the Scicon Phantom 230 has just enough room - 230ml, hence its name - for a spare inner tube. You might manage to squeeze your house key in there too, but Scicon’s suggestion that you could fit in a CO2 cartridge and a patch kit looks ambitious if you carry a standard butyl inner tube with you. It’s an either/or option.

Carrying capacity is limited but the Scicon Phantom 230 includes tyre levers

So if you want to guard against the majority of on-road hiccups, you’ll need to carry some stuff elsewhere - probably in your jersey pockets

But what the Scicon Phantom 230 does really well is to give you a small amount of extra capacity unobtrusively. It sits under your saddle and is small enough that it’s not going to get in your way as you ride.

Plus, it’s held in place really securely by the clever Roller 2.1 clamp. This fits to your saddle rails and is tightened using a large red screw. Unlike some systems, this means it’s tool free and the size of the screw head makes it easy to get enough leverage for a tight fit.

Rail clamp is easy to attach and gives a stable hold

Once the clamp’s fitted, the Scicon Phantom 230 bag slots onto it at an angle and turning it clicks it securely in place. It’s a simple, effective system and keeps your bag away from a delicate, expensive carbon seatpost. There’s a light loop built in if you want to attach a rear blinkie to up your visibility.

Another useful feature is the two red plastic tyre levers built into the bag’s mounting point, one inside and one outside the bag. They’re reasonably robust, but the plastic feels slightly brittle and they are a bit short. I wouldn’t rate their chances against a tight tubeless tyre.

The £35 list price makes the Scicon Phantom 230 an expensive option on a price per volume basis, but it feels sturdy and well made and its easy on/off mounting system is a definite advantage.
