Which Groupset?

Or you're designing a FS MTB and the suspension linkage wants to be in the same place a front mech would be. Or if you're SRAM and can't design a decent front mech. Or if you live in the flatlands so don't need the extra range a second chainring provides.

The first one is a proper reason and falls under the dirt herder category. The others are not.

Innit. For me, it's not about range. It's about nice small jumps. I'm finding the jumps on an 11-30 too big with a compact. Let alone a 42t cassette with a single ring up-front. Eurgh.

Fixies don’t jump at all.

Yes, was thinking of a 42:17 single speed hack for my trainer bike, and now I’ve got SRAM.

I quite like not thinking about front shifting when my attention is focused in navigating rocks, roots and puddles.

Second one, deliberately so. Third one I consider valid based on personal experience. I can't think of any ride within 50 miles of home which wouldn't be eminently suitable for a 48 tooth chainring and an 11-25 cassette. None of the climbs are steep or long enough to require lower gears, and none of the descents are steep or long enough to require anything higher. Unless you're on a TT bike, in which case replace the 48 with a 54.

Well, 'scuse the hell outta me. I was tooling around 'London's famous London' on a 'fixie' only this morning.

But you're happy to think about rear shifting? Uh huh.

1x is a fad, nay! a conspiracy from bike manufacturers because bike forums had got the word out to too many people that crossing chaining was a bad idea and they needed something to ensure expensive cassettes and chains were worn out. Enter the 1x. Cross chaining guaranteed and now the massive wide range cassettes cost a fortune and oh you need to buy a new hub to use them too?

I mean, that's a total joke but now I've written it there might just be some XD driver dude rubbing his hands together laughing while he jumps on his 3x10 MTB and rides off into the sunset.

Lies! Wait, did you have e-assist or a pizza rack or were you actually driving a Prius stuck in gear? Those I could believe.

If it's flat ride fixed. If it's not flat, FD keeps your chain on (it's Millar time!) and the little ring lets you travel with your bike to places that aren't flat or deal with places when you're 'flat'. Don't bonk me this waaaaay. I can't survive, I will surely have to drive, don't bonk me this way....ahhhhh...

Y'all can justify the 1x con anyway you want but I'll keep my standard freehubs, standard chains and chainrings, nice chainlines, bigger gear range and built in chain retention.

Those XD driver hubs do look handy for running a 10t cog and being able to bomb down a mountain with 140 gear inches.

Again, might wear the chain faster than necessary.

Perfectly timed for this thread - the rumour is campagnolo are about to replace Potenza with a 1x group.

Yeah but if you had a double you'd have a whole set of bigger gears already :)

I'm fine not being convinced 1x is a good idea. Maybe I'll ride something muddy enough to ruin an FD and change my mind but right now, nope.

My Shiv is 1x for da aeroz and, even on the road with 1x chainring, chain drops fucked a couple of races before I pot a hacked FD back on for proper chain retention.

Who?

Ah thanks. I did look at the Shimano tech site and found it to be so. North of £200 for a new Cannondale compact ring pair though, seems an awful lot.

Standard legs on 48 x 17. Nothing like 'back in the day' when one would do 'traffic jamming' on 49 x 15. Also, no 'pizza rack', indeed no bottle cage bosses either, so venturing beyond inner London districts a no-no

A filling for your panino?

What sort of rings? Spider rings? I still have a new set of the FSA rings that came with my Cannondale SL? cranks.

Show me the food!!!

brakless?

Certainly not 'brkls'. A pair of R7000s is fitted. As for the Dale, first thing I did was to remove the FSA rings — cranks are now SiSL with 10-spoke SpideRing, hence the hellish cost to replace. I do have a 50/36 Praxis Works pair on an Si crankset but they are a bit ho-hum.

I don't see the appeal in those Spider rings. But I'm boring and sort of sensible and ride too far to pay that much for something that's just gonna wear out. Chainrings are chainrings and they all just seem to work unless you've bought proper cheese.

I've had not entirely good results with Praxis Works rings. Rotors are now my go-to choice on non-Shimano cranksets.
