a basic cassette, ultegra compatible chain and ring alone is £180

That seems expensive. Where are you shopping?

Also, why the fuss over 1x? Depending on your RD you can probably already run 36 to 42T cassette and even if you wanted lower gears, a Wolftooth and 46T MTB cassette is way cheaper than the prices you're talking. I decide against those bar end junction boxes too because they'd make charging Di2 while riding a pain in the arse. If you're worried about neatness there's cheaper ways of hiding cables.

1x seemed like a neat idea when I decided to switch my road setup to more of a road plus / gravel but now after looking at it I’m happy with sticking to 2x for the mo...

More than £180

As far as the di2 charging box goes not sure what you mean? You’ve charged your battery while riding? How big are your rides?
“ A modern Di2 battery is said to last between 2000 and 5000 kilometers per charge. This depends a bit on how often you shift and also your shifting style. The front derailleur has to work harder than the rear derailleur and thus also consumes more energy”

There’s nowhere better to hide the box on a ti frame when the bar end solution exists but I will buy new bars (zipp xltc SL) for the di2 routing instead of drilling my current zipp bars
The frame has internal routing for the gears and hydraulics so make sense to go full neatness 🤷‍♂️

How big are your rides?

Lel.

Quite a lot of that seems like bike shop bullshit. And RRP. Who pays shimano RRP?

Yes GRX is expensive but you dont have to go GRX to go 1x with di2.

I’ve shown the online some of these 25% less than retail prices here..

Closer to £200 and I’m not knocking 1x - I’d like it, but it does mean scrapping my perfectly good cassette, chain and ring when I’d rather spend my upgrade money elsewhere (for now)

I decide against those bar end junction boxes too because they'd make charging Di2 while riding a pain in the arse.

Got to agree. My tripster has a bar end junction and there's no way I'd ride and charge it as there's too much flappy cable. I did it that way as the price difference was negligible and I wanted something less exposed. Got the under-stem one on my normal road bike though; the increased effort in cabling wasn't worth it for me.

@tilover - Why XT? If price is a major driver, SLX/Deore parts are also available and you'll save 20-30% and add probably 50-60g at most.

Why does anyone need to charge while riding, the battery’s last 2000miles? They’d last a non stop LeJoG with ease

As for SLX options, because it’s a titanium and carbon ultegra specced bike as is, seems crazy to downgrade components to entry level just to try a new system. I’m of course not against spending money but on this occasion sticking to the 2x makes the most sense, if I do change eventually it will be to equivalent spec or better 👍🏻

If anything, your lbs prices are fairly cheap. You can't change your drivetrain for £50

Yeah, I think the prices are good too

Oh for me there'd never be a point. For some of the people on this forum, 2000 miles isn't enough.

😂 impressive dedication, I’m fine with a monthly charge overnight to keep it topped up and will be glad to see the ugly stem mount gone for sure

if you are not in a hurry, lightly used stuff on ebay/FB marketplace is plenty

not having a go at you, I was. in a similar situation; having to build up a Di2 only frame with 1x; I 'compiled' a whole groupset for about £550-£600 incl everything. The slightly older stuff is very cheap; the best value thing to do right now is XT Di2 rear mech with ST-R785 shifters. Again only possible with hawk's eyes on ebay/FB marketplace/other classifieds and a desk job.

I normally buy 90% of stuff used on eBay or Forums but this time It’s at the lbs being built, I’m not gonna faff with internal wiring / routing and rebleeding myself

Total bill of parts is about £500 ( at a good discount under retail and no labour costs as they are good friends) and good thing is I can sell all my unused bits for slightly more than that so I’ll have saved money overall

Don't we all like to tell ourselves this

😂 I’ve estimated modest prices I think, will probably get more given lockdown

Hunt x mason wheels with gravel king tyres £250ish
Zipp compact drop SL bars £35
Ultegra Di2 levers and brakes £150+
Old frame and forks - 58cm rose Xeon di2 £100+

Hit me up if anyone interested

Unless you really think 1x will be an improvement to how your bike rides all it's likely to do if give you less gears with bigger jumps in-between, a worse chain line, more chance of dropping the chain and more chance of a slack chain hitting your stays.

... and less money in your sky rocket.

Yup - this

Also this

Is this a legit place to use "do you know who I am?" :D

Just remeber to charge the Di2 before leaving the house and you won't need to charge it while riding! All of this faff to ride down the road to the corner shop..

Also, 1x are way overrated.. Not really loving my new 40x 11-40 setup at the moment. I find the cassette jumps particularly annoying

I will convert to 1x when we get to 20-speed
