Which Groupset?

Depends which Garmin. My 1000 has had a couple of 'rain deaths' so I've filled the SD slot with silicone grease and tape it shut. It should be pretty solid now.

After its last rain death, mine has a screen with a slightly yellow tinge and the touchscreen works even less well than normal, which is saying something. It'll be going back for fixing when I find a reason not to just use an Elemnt instead.

Ideally I'd like 52/36 but that definitely doesn't exist in silver. A recent injury means I need to be nicer to my joints so maybe I will hunt out a compact. A part of me just wants to skip the faff of ultra/powertorque and get a 9 speed Athena crank and throw 10/11 speed rings on them, they are genuinely beautiful:

SRAM has an ETAP MTB group coming apparently

Is there any point (in terms of performance) in me upgrading my 4600 rd? It's paired with 5700 shifters at the minute.
It would scratch 2 itches for me: buy a bike bit, get rid of tiagra from the bike

Supposedly rear derailleur is the one that have no performance effect other than weight for the higher groups.

Very exciting if it works with HRD shifters.

Might buy a TI hardtail now.

.

What are peoples experiences of the Tiagra 4700 groupset? Was initially planning on going 1x to cut cost but the 4700 seems really reasonably priced - with the only downside being 10speed and iirc the crankset has an odd spacing between rings that would mean it'd need replacing if upgrading to 11 speed?

Would like a 44-46t NW 110bcd chainring. The Hope 'Retainer Ring' looks decent, but I assume an eBay/AliEx thing would do the job.

What are people's recommendations?

I've used 4700 for a year. It's great. Heavier shift at the front but it's no bother and not too noticeable compared to the 5800 that I run on my other bike. Craps all over the Sora that it replaced. Also I've not had to make any adjustments to the shifting since I set it up. Looks good too!

potential silly question but can I use an 11speed SRAM front mech with chain catcher on a SRAM 10speed group? any issues?
Cheers in advance,
Matt

Yes. Think the chainring spacing is slightly narrower on 11 speed so it may rub a bit on the extremes of the cassette though

Yes, I'm doing exactly that. Replaced the old mech on my SRAM Force 10-spd group with Force 22 with Yaw, with big improvement in shifting.

This isn't something I'd considered, but my actual experience is no rub, because of the Yaw, all the way through the cassette.

Is great! Have it on mine and my partner's bikes.

Much better than the old Tiagra. Great mix of function/value.

No point, the only advantage is weight saving but that’s it.

Using a blackspire 40t n/w 110bcd here - no complaints

Yes*, but it's SRAM, so the front shifting will still be shit, as evidenced by the fact that SRAM feels it necessary to fit chain catchers as standard on their front chain ejectors.

• I've got a SRAM S700 levers/Red Yaw FD on my CX bike. Constantly throws its chain, regardless of setup. Total PITA.
  

Superstar, if they do that size.

Ultegra 6800 is currently going for £470 online. Does anyone have a feeling that it's going to get any cheaper or is this as low as it goes until stock clears?

Wolftooth are good.

I would say it's better than 5700 and more like 6700. I haven't experienced it but seems to be a lot of left shifter issues.

think the demand is pretty high still so most likely not
