Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

Mantel seem to have two listings for the R785s, one at £308 and one at £385.

Don't know what the difference is...

calipers

Aha, don't know how I missed that. You could buy a pair of the new calipers for less than the difference though couldn't you?

You'd (guessing) need hoses, hose fittings etc, would those come with the calipers?

What is a better deal?

The whole Ui2 Groupset

or just the gear kit

I might have a full 6870 for sale soon for £600 if you're interested, 3 months old.

I might be interested if you did.. why you selling it after three months?

Cuz I have two sets of 6870. Recently got sram red 22 so decided to at least have one mechanical roadie

Can you ride di2 while it's charging? Wondering about using dynamo to recharge di2 battery.

I think you can, I can shift while it's charging..

How long are you planning on riding for?!

For sure.

How long and where are you riding? ;)

Can I run a 30t cassette on a short cage 6770 derailleur?
Edit - Question Answered.

TransAm record is well over two weeks for 4200mi.

You're a mentalist!

Any advantages to DA Di2 compared to Ultegra Di2 in the road bike group? Presumably some weight difference but anything else?

fancy hidden garmin switches but thats about it ..

Don't suppose you know the weight diff/ price diff off hand?

Spanks

Ultegra di2 St,Rd,fd weights 295 250 155
Da Di2,237, 217,114

tbh I didnt think it'd be 600g+

If I ever get a Di2 bike again it'll have DA or etap

150g and a shit load of money. Guess it depends if I was buying the whole group or not. It'd probably be just the shifters/deraillers.
