Again. There is no such thing as 685 callipers.

There is, but it's off series, sold to OEMs for bike building.

Same as there's an R565 chainset and brakes, which you can't buy, but which I have on my Tiagra equipped bike. They're about 105 grade kit. A good job as well, as the Tiagra 4600 chainset looks minging, and the 565 one is much nicer.

Are you absolutely certain that the ones you have are 685s for the callipers and not just 685 levers with 785 callipers? Everywhere I've looked when you attempt to purchase the road hydraulic discs you'll get the 685 sti + 785 calliper combo.

edit: Von - not trying to be an arse but please can you link to proof of that (685 callipers existing + being OEM)? If I'm wrong I'll happily admit it but I've not seen any evidence of that at all and it would surprise me that Shimano would bother introducing a lower model calliper but then generally not sell it with the 685 sti levers.

Googling all over the show turns up results for 685 calipers, but always in conjunction with 785 levers, so maybe there is no such thing after all.

So... I dunno. There is off series kit, but maybe this particular bit doesn't exist after all. I guess it wouldn't be the first time a bike spec was listed wrong.
 
Well, it's not conclusive I guess but I think I'll stick to my current conclusions then :)

It was actually kind of stressful for me when my brake kit came with 685 levers and 785 callipers - I at first assumed something been mixed up in the order and they would be incompatible. As I'd ordered them from some company in Germany it would've been a massive pita to sort out.

edit: Also, FYI, both 685 and 785 levers are in the Ultegra/DA range. The upgrade difference between the two is just the Di2 compatibility in the 785s.
 
I did see talk about improved cable routing but it could have been br-r vs br-rs instead of 685 vs 785.

With the front gear changes, it has 2 clicks to go from large to small chainring, is this normal on a 2x11 system? first click moves down but will rub in the 3 largest rear sprockets. The 2nd click fixes this but would rub on the 2-3 smallest (not really an issue). Moving up from either is just one lever movement. Can't remember the hi-mod demo bike doing this.

Yes, it's normal - 2nd click is trimming.

"A trimmer allows fine adjustments to be made to the position of the front derailleur to prevent rubbing."

Riding a single speed bike is like training with grudas, because no matter what the problem is, there's only one answer. Want to go faster? Keep pushing. Hill a bit steep? Keep pushing. Spinning out on a descent? Keep pushing.
Sounds about right!

Your bb. 107mm sounds a bit narrow to me. The narrowest JIS square taper is usually 110mm for 1/8" track chainsets. ISO ones come in a 107mm and 103mm because the taper is shorter. As said, the Shimano UN55 is best bang for your buck. There's really no gain in shelling out more.

On the subject of SS and fixed, I've got to switch to geared for a bit. My right knee is really playing up, bad enough that I'm going to go and see the quack about it. So if anyone sees someone crawling along at comically slow pace on an old Bob Jackson with a disc wheel then it's me :(

Been there, done that.. ! Pretty much the whole week was on the 32t rear ! The pain was mental on Wednesday! But yeah the BB is 107mm :) that's what I've got with strong light bb and track 2000 crank! No problems, metal cups and looks very similar to my un55 that I've got in my triban 3 frame.
 
Does anyone here read any cycling magazines regularly?

I've got this weeks Cycling Weekly and its quite nice to read a physical magazine rather than a website.

Also got a couple of copies of Cycling Plus that I've read on the train etc.

Any recommendations?
 
I do quite fancy building a SS/fixie based on everyone talking about them. I wonder if I could make a super light fixie with a chinese carbon frame and over-spec'd light wheels? :p

You could do it with a regular frame if you used an eccentric hub or bottom bracket. If it were a frame with internal cable routing you wouldn't have to worry about unused cable guides ruining the look of things.

You're probably best with a decent aluminium or steel frame if you are interested in it though...

My neighbour dumps loads with me from time to time as he reads tons of them!

Cycling Weekly is much more focused on pro cycling.
Cycling Plus is a good one, put out by Future Publishing and linked heavily to bikeradar.com. Loads of adverts for Ribble and Dolan!
Cyclist is a fairly new one, I've read a couple of issues of that and it seems pretty good.
There's also quite a fancy one called... something... I forget what. Cycling? Maybe? That's a bit more high end, heavy paper and so on, quite detailed features about cycling on the continent and the like.
 
Rain forced me in to Whiteside on the Turbo this afternoon. Longest turbo ride I've done, previously an hour, and also the longest FTP too.

My 'sit-bones' are absolutely ruined, help. Tried to move around as much as possible on the saddle but it's difficult to change position and remain effective & efficient without having your legs start to blow.

Distraction is a bit difficult on relatively flat/boring workouts, some TV helped but mostly a generic dance/trance/drums based spin youtube compilation spurring me on.

The ride felt comfortable (apart from my arse) so could probably knock it up a gear, though this is supposed to be 95% FTP and I bumped my FTP up 20 watts from the 20 min test based on my other rides being a bit too easy.

I find my arse hurts a lot more after a long turbo session compared to regular riding. Moving around helps a little but as you say, not enough. I try to practice riding in an aero position a bit whilst I'm on there to help.

Looking forward to seeing what you end up eating to try and eat back all those kcal btw :p
