Birzman Feexman E-Version 10 Multi-Tool review

Birzman’s Feexman E-Version 10 Multi-Tool features 2.5mm, 3mm, 4mm, 5mm and 8mm Allen keys and a 6mm L-shaped Allen key that fits into the end of the 8mm and can be used to operate the 8- to 12-speed compatible chain tool. There's a T25 Torx key and Phillips PH1 and flat-head screwdrivers, too.

Each tool is made from Chroma Vanadium steel, except the chain tool that’s fabricated from alloy steel, while the side plates are made from standard steel.

The tool weighs 120g and is 50mm wide, 18mm deep and 68mm long. Its general construction feels solid and robust.

With the bits on offer, the Feexman E-Version 10 is best-suited to trail-side adjustments and light repairs rather than being relied on as a get out of jail free card. There’s also the notable omission of a 2mm Allen key.

The simplistic construction meant the Feexman E-Version 10 remained tight during the testing process, and the tension of the tools was easy to adjust thanks to the 3mm Allen key pivot bolts.

The tool remained rattle free, including the chain tool, despite there not being a dedicated stash bag or securing rubber strap.

Allen key sharpness was spot on. The 6mm Allen key was fine for low-torque bolts, but as soon as more force was required its L-shape design meant that applying more pressure was tricky because the tool folded around itself. Although the bit’s angle is adjustable, because of its shape, it was always off centre and I was unable to find a position to reliably put lots of pressure through it.

Torx accuracy was good, too, and the bit was long enough to access disc rotor bolts without the tool’s body making contact with areas I didn’t want it to.

The missing 2mm Allen key meant that adjusting brake lever reach on some brakes wasn’t possible, and the length of the bits and bulk of the body made it tricky to reach the adjuster where a 2.5mm Allen key was used.

However, the 5mm Allen key was long enough to reach all of the bolts I needed to access regularly. The removable 6mm and 8mm tool was fastened tight enough for me not to worry about losing it during transportation, but the retaining spring was loose enough for it to not stick.

The chain tool’s design relies on detaching the 6mm Allen key, but I found it wasn’t long enough to provide enough leverage to split stubborn chains.

This proved to be frustrating trail-side when wet and cold. As a solution, I used a second multi-tool to operate the chain tool’s 6mm Allen bolt head, but this wasn’t ideal.

I struggled to find many applications for the two screwdriver bits and would have preferred one of them to be replaced with a 2mm Allen key, knife or additional Torx keys.

Birzman Feexman E-Version 10 Multi-Tool bottom line

A reasonably well equipped and quality feeling tool with sharp and accurate bits, but the chain tool was tricky to operate when I needed it most and I thought the screwdriver bits could be substituted for more bike-specific pieces.
