SRAM X0 front derailleur, in silver/black, 3 x 10 S3 Low Mount 44T Bottom Pull
It's been taken straight off my new bike as it is running 1x10.
This is the 3x10 version, and is direct mount fitment - it comes with all bolts and spacers to attach to your bike, provided of course it's a direct mount fitment on your frame! It was fitted to a 2 x 10 system as standard so I assume the capacities all work for 2x10 as well.
Retails at £49.99 on CRC at present, against a £60+ RRP:
