  • Not realised that too, would've thought they don't need to due to the longer chainstay.

  • All they've done is moved the freehub a little bit inboard to you can have short road bike length chainstays and still have a chainline that will work with all gears. If you run the non SCS hanger it just means you can't run little/little because the chainline is off. It's part of the stipulations from Sram and Shimano about chainline or chainstay length if you want to fit their groupsets to your bikes.

  • That Diverge is Thereabouts 2 I am pretty sure. Buy it.

  • You've got more Spesh than I do! Where you do work? One of the Concept stores or something? PM me if you don't wanna 'reveal all'.

    I'm riding an old 56cm Tarmac w/ 110mm stem. I'm looking for a bike to race TransAm with so I'm not sure about how suitable the Tarmac would actually be since I'd like try and run fat tyres on it. I can squeeze 28s in my Tarmac but it is very much a squeeze.

  • Short Chain Stay

  • After many emails with Bruce Dalton from Kinesis (seems like he has a bot answering them, because the responses are always late and useless... redirecting my questions to the appropiate department whould be better), and then guys from MerlinCycles... they finally managed to get some Di2 Grommets from UpgradeBikes for me (for free).

    Also, if anyone has problems with Kinesis, better ask them through facebook messages! they are much more competent and quicker in their responses... but still not answering difficult questions like... Why you provide a 160mm rotor adapter when the frame doesn't allow that size?

    The plugs installed:


    The part code is: UPG-G10-ST "Grommet G10 for Seat Tube"

  • Is anyone using the BB junction box?

    A couple of Qs; 1) is it much more of a faff than the stem mounted one and 2) can you still use the internal / seatpost battery?

    Cheers.

  • Unless I misunderstand you. You need both.

    • Junction B at the BB. Which is simply a 4 port Box (battery, rear mech, front mech, Junction A).

    • Junction A at the stem. Which is the one you plug into to charge, and use for trimming. The shifters plug in here (as well as TT shifters if its a 5 port) as does a cble that runs to Junction B.

  • Ah, right. I see.

    Cheers.

    I'm just trying to work out the most economical way to collect a Di2 + R785 set up.

  • Cant you just buy a R785 groupset?

    Individual Di2 parts arent cheap. Plus the cables, charger, Junctions, battery, etc. all get pricey bought seperatly.

  • You can pick up parts cheap if you keep you eye out.

    External battery and sw-67 junction can be had very cheap for example.

    Managed to get a 1x11 setup for under £300

  • Di2 noob here. Battery in seat tube and giving bike first charge. Light on junction box is solid red when button pressed. Is the light supposed to come on when charging?

  • What charger have you got, the one that plugs into a PC?

  • Yeah, that's the one. Have worked it out now. Was pressing the button on the bottom of the junction box in error!

  • Ah, yeah that puts you into trim mode.

  • Why is my bike so noisy in the smaller sprockets at the back? It's not trim, I wonder if I've not done the cassette up tight enough or put a sprocket on the wrong way or something. I can't be bothered pulling it out of the turbo to find out. Very annoying as it's usually buttery smoov.

  • is it a new cassette?

  • have you put the spacers(s) in?

    I discovered on one wheelset I needed 2 spacers rather than the 1 I thought I needed to had a correctly torqued cassette that sounded like a bag of spanners...

  • New-ish. It could be less-used teeth but I'm sure it wasn't making that much noise the last time I ran it. Maybe it's just more noticeable on the turbo when previously I was using it outside.

  • B-screw?

    Need to screw mine in for turbo use as I have a big cassette.

  • Yeah, I've fucked up the cassette spacer thing enough times that I think I've got it nailed these days. The sprockets aren't moving though so I think it's good.

  • It's noisy on the small sprockets though, not the big ones. If the B-screw was off and the jockey wheel was interfering with the cassette, it'd be the opposite.

  • Quite often my front mech rubs the Chain when using my turbo wheel.

    Combination of oval rings and a 16-27 cassette.

    I find headphones help.
