With new 2018 bikes starting to hit shop floors, it’s the recently announced Shimano R8000 groupset that’s getting the most attention. However, prior to the release of this new groupset was one that slipped straight past us – a new Shimano 105 front derailleur. Thanks to reader Mick (@neutralservice on Instagram), we’ve been made aware of the new FD-5801 105 derailleur that’s now being shipped on some 2018 bikes.
This new derailleur borrows the design from R9100 and R8000 mechanical front derailleurs which sees the traditional lever arm replaced with a spool-like assembly. Its cage shape is optimised to better handle wider axle widths (such as those on disc-equipped bikes) and large cassette ranges, changes that likely lead to less rub when cross chaining, too.
This low profile design improves leg and tyre clearance, and incorporates a handy cable tension adjustment to make inline adjusters redundant. Lastly, its received similar leverage ratio tweaks as its Dura-Ace and Ultegra seniors, which should provide for reduced hand effort required to shift. This new front derailleur is compatible with all Shimano 11-speed road drivetrains.
Joining the front derailleur is a new 105-level non-series crankset, the FC-RS510. This crankset features Shimano’s four-bolt chainring design and features a wider Q-factor for use on disc-equipped road bikes.
