Full 22 speed.

Out of the box, the Tern Verge X10 uses a single chainring on its crankset. This is actually good enough to get you around the city on flat surfaces with minimal elevations. However, if you want to go uphill, you'll need a second smaller "uphill" chainring and a front derailleur.

Below is my previous set-up which uses a single 55T chainring without a front derailleur (FD).

However, installing a double chainring set-up on a Tern Verge X10 is not as simple as buying the needed parts and slapping them on the bike.

Road FDs are usually bottom pulled, thus the shifter cable needs to be secured below the FD. One thing I needed is the LitePro FD mount/clamp. However, if you'll notice on the picture above, my bike already has a mount welded on the frame's down tube. So, why do I need a clamp then? Simple. On road bikes, the cable runs toward the bottom bracket and to the FD with the use of cable guides. My bike, on the other hand, doesn't have the said cable guides.With the use of the clamp (without the included mount), I was able to use its stopper to secure the shifter cable on the down tube.

For this set-up, I used the latest SRAM Force 22 Yaw front derailleur (previously only available in the SRAM Red). Here are some of its features:

Yaw™ cage rotates in line with chain, improving the shifting speed and precision while eliminating the need for shifter trim.*
TRUE 22 – twenty-two usable gears in all gear combinations with no rasp or rub.*

*Details taken from the official SRAM website.

These technologies from SRAM actually gives me 22 gears at my disposal, in contrast with the traditional 11-speed set-up.

With the problem fixed and the two chainrings (53T and 39T) installed, the transformation is complete.
