I got a bargain last night a set of DI2 785 shifters for £120 in immaculate condition. I have di2 FD (8070) and think I have the right length di2 cables so just need to get the rest of the kit. Will use existing calipers so think I just need RD, battery and junction boxes. Etube is for connection to PC right? Is the di2 bar end thingy worth it on non integrated bars? Could obviously change bars to integrate cables but without a frame capable of internal through the headset maybe it's too much of a faff. Unless someone is aware of an integrated combo which retro-fits? Now that would be something which sells well!
Many di2 guru's around here for some feedback on this?
Think I've read before that mixing and matching di2 can be done, like older 6870 shifters with newer R8070 derailleurs? Can you mix the derailleurs too, so an old series FD and a new RD?
Okay, back to putting these new wheels on my hybrid... can someone confirm, the disc of my current wheels are different and not compatible, right?
I don't mind buying new discs, in some ways I prefer it anyway.
As mentioned top is 6-bolt and lower is Centrelock. Centrelock is Shimano so you generally find only Shimano rotors are Centrelock. So going 6-bolt does open up cheaper rotor options. You can get an adaptor to fit 6-bolt rotors onto Centrelock, but not the reverse. So with one of those you could fit the top rotors on the lower wheels if that is your aim...
I've got one for wheel bearings and it's a faff to get in, too tight a space in the recessed hubs I tried it in to get the angle required to get through the 'outside' bearing. Probably have more joy with one on a BB as there's more room.
Are you looking for the cheapest way to get out a press fit BB? What's the BB size?
I've got a Lifeline BB30 version of this and it works well -

At least you actually tried. I've still not bothered
I tried... Twice!
I probably haven't done one since late autumn/early winter so very overdue!
I managed a 20 mile ride at about 14mph. Can only improve from that now
Good to hear you've been feeling well enough for even that! Think you're in the all clear now?
Looking at your Strava - you changed gear mid way through it, cadence dropped, power went up to 300w av from 280w average, then you blew up shortly after.
This was the final interval before a 6 minute rest and the actual test. First part 3 minutes at 280W I could handle but knew by the feeling I couldn't sustain that for 20, HR climbing and beginning to blow at the end. The interval is then straight into 2 minutes at 330W as soon as the resistance came my legs popped and I stood just to see if I could maintain it to then settle down and rest for the test. Nope!
This is with my FTP set at 255W. It was set at 261W from some of my racing over the winter and I think my last actual test was nearer 250W. I've not had a scout of my recent outside power data from the last 6 weeks (probably my next port of call) to get a best guess of what I've been doing outside. Some of the speeds on the loops and segment times are better than quite a few years ago when my FTP was 270W, so I'm hopeful for a nice little bump!
I'm currently in 2 minds what to do, cooler weather and a bit less time this week & weekend means I'll be Zwifting. So either base work this week to test again on the weekend, or get some races and sustained efforts in to get the feel back of riding on the turbo to test in a weeks time. As it just could be that I'm lacking, Zwift 'feel'...
But with the weather due to be warmer/better later next week I could forget about an indoor test and head to Gospel Pass or The Tumble for a real outdoor FTP test up a long climb. Which I've never done before!
