I am leaving in plastic so it is brand new, but that makes for not great photos. To accommodate the wider 135mm rear spacing of disc-equipped bikes while keeping minimum rear-centre sensible at 410mm, latest group sets have slightly spaced chain rings and a re designed chaining tooth profile. To reduce effort at the end of shifting. The rs510 is a non-series.
Fd is this really part of a new 105 group set. If tease for whole group set, Shimano isn letting on. Brand new in box Shimano 105 front derailleur for 2x11. Stuff stolen from internet: badges the FD-5801, new derailleur does away with FUDs long lever arm, which means no more cables rubbing on tyres and potentially tyre clearance full stop. It includes the same built-in Allen bolt cable tension adjustment as latest Duran-ace and ultra offerings, awkward jibs-standard cross-head limit screws have also been replaced with hexes.
The optional integrated power meter and bold aesthetic changes grabbed headlines, but from an actual shifting point of view new front derailleur design was more important.
This is the clamp-on they call it band for 34. Non-group set crank that you re likely to see a whole lot more of in 2018, and it uses the same chaining spacing as Duran-ace r9100 ultra r8000. Duran-ace r9100 was released in 2016 and ultra r8000 arrived 2017, so it would be quite logical for a new 105 group set to follows fully backwards compatible with older sifters cranks.
It would certainly make sense, however. Whats the point of FD-5801. As a result, the new derailleurs required slightly wider range of movement and subtly re designed cage.for the band-on version.
And riders should see an improved shift action by adding it to their existing group sets. 9 tubing, 6800 etc. In addition to these practical touches, the FD-5801 promises just as r9100 and r8000 did a new geometry which more closely matches force curve of hand.
According to Shimano brand manager mark Gresham, the FD-5801 was created primarily allow bike makers spec latest rs510 cranks on their more affordable disc bikes, and its not clear if will actually replace standard 5800 part completely. Interestingly, the two FD-5801 variants are just 6g heavier than their ultra r8000 counterparts. Came as part of new bike build kit, but using other.
