    Potential Shimano Upgrades for Specialized Diverge

    Hello Everyone,

    I was looking into Shimano Groupsets or Partial (5 piece) Groupsets to upgrade a Specialized Diverge Elite. I understand that I could use parts from the 6700 Ultegra series 10 speed parts. Given the relative scarcity of those items I was searching around for new parts. I'm generally considering wheels as a separate upgrade and am looking to avoid not have to buy a new set of rims/tires.

    Will a Shimano 6800 (11 speed) full groupset with hydraulic brakes work on the Diverge? Would a 5 piece set like those sold by Colorado Cycle work?

    What's the 1.5 pedestrians--Your body count (so far)--like one was DOA and the other only half dead?

    That would be the average fatality rate of pedestrians killed in traffic crashes, on average, between the age of 15-19 statewide that I reside in according to the NHTSA. Yeah, now don't you feel bad.

    According to the National Highway Traffic Safety Administration for the latest year complete data is available (2013), Delaware has the highest fatality rate in the country with 2.70 Pedestrian Fatalities per 100,000 people. 2014 preliminary statistics were showing Florida overtaking Delaware.

    But about them bicycles...

    Actually it appears that you are correct (I just double-checked). I am at a total loss to explain how I could be wrong because I know I read it on the Internet.

    So, to answer your original question, I know a little about transportation in general. Just not a whole lot about bicycles.

    You can certainly change your component group from 10 to 11--but you would have to replace at least the rear wheel, since an 11-speed cassette will not fit on a 10-speed freehub.

    The Elite has Shimano Tiagra, 10-speed, 12-30 cassette. All you need to do to convert it to 11 speed is remove the spacer ring behind the cassette.

    Sorry Poonjabby,

    Could you clarify what you mean? I know about the spacer but not how that affects adding different parts...

    Do you mean I would be able to purchase a Shimano Ultegra 6800 groupset and still use the same wheelset (as mentioned by clarkinHawaii)?

    I believe you may be mistaken.

    OP--Just Google "11-speed cassette on 10-speed freehub" for yourself. On Shimano, you can't do it.

    I'm getting conflicting information from the old Google search.

    Road.cc states:
    Shimano 8, 9 & 10 Speed Cassette Compatibility With 11 Speed Freehub
    The Dura-Ace CS-9000 & Ultegra CS-6800 HG-EV 11 Speed Cassette is 1.85mm wider than a 10 speed HG cassette, therefore the freehub dimensions have been adjusted accordingly. In order to mount a CS-9000 or CS-6800 HG-EV 11 speed cassette, an 11- speed wheel must be used.
    Bicycle StackExchange states:

    Shimano/SRAM 11 speed cassettes are wider than 8/9/10 speed ones. So yes, you need a new, wider freehub body, unless your old one was not very old and used a spacer to fit a 10-speed cassette.
    For 11 spd road drivetrains Shimano uses a 1.85mm wider hub with the drive side flange closer to the centerline to compensate for the additional width. Using a spacer allows the wheel to be backwards compatible to fit a 10 spd cassette. You can't fit a 11spd freehub in place of a 10spd freehub unless the wheel has been built to accommodate it.
    Some hubs are, usually 2012 or later hubs from better brands, are able to be converted. Others are not. It is different for each brand.
    I think I need to take a close look myself...

    Trust me--I proved myself to be reliable with the pedestrian-kill issue, right?

    Actually, Shimano freehubs have been the same axial length since 8 speed. Then they made 9-speed cassettes the same length so they fit the 8-speed freehub body. They along came the 10-speeds which (counter-intuitively) require a 1mm spacer to fit properly on the 8,9 speed freehub.

    Then along came 11-speed cassettes, which are just too wide for the previous freehub and a new generation of Shimano freehub was born. You can use 7,8,9,10 speed cassettes on the new 11-speed freehub body (with appropriate spacers). But the 11-speed cassette will not fit on the previous generation Shimano freehubs -- it extends out so far that you cannot engage the lockring.

    That's all from me on this subject

    Alternatively, would a 7900 Dura Ace 5 piece group set fit without needing to replace the wheelset?

    The Diverge was new for 2015 for Specialized. If the Shimano hub has a spacer on it now you can add an 11 speed cassette just remove the spacer.

    I just added a Shimano 6800 Groupset to my Roubaix. It was Shimano 5700 Groupset 10 speed. I didn't have to change the wheels. All of the new Shimano hubs are 11 speed compatible hence the spacer ring.

    OP--take off the cassette. Underneath should be a spacer either 1mm thick or 3-4mm thick. If it's the 1mm spacer (or no spacer) you cannot use an 11-speed cassette. If it is the thick 3-4mm spacer, then it is an 11-speed freehub.
