Good morning. Thanks, Kurt. I I struggled with the 1x vs 2x decision for a long time before committing to the 2x. And I was pretty confident I made the right decision until now. I think you're right, the 1x would solve my problem -- that 1 ring would sit, I think, almost exactly where my current big ring now sits. And I get no chain rub while in the big-big combo. Not a ton of clearance, but it's definitely not touching. The only problem, and this is a huge one, is that I've already bought and mounted all the 2x parts -- crankset, cassette, derailer, and even left hand shifter. These would all have to be replaced at great cost, unfortunately. So, as much as I might be wishing I'd gone 1x, I think either a new skinnier tire, or simply not using the low-low gear of the 2x makes a lot more sense money-wise. Now, if it turns out that I don't get good shifting with this set-up, or if chainsuck becomes and issue, you just might see a bunch a lightly used 2x12 XT parts for sale on eBay to fund new 1x stuff.
Glad to hear that you like the Honchos! Oh, and can you explain what a "clutch derailer" is? I've looked at the differences between Shimano's 12 speed XT RDs and neither mentions a clutch. The only difference, as far as I can tell, seems to be capacity. Am I missing something? What is a clutch? Thanks, Ryan. Thank you for the photos. I agree with everyone else here and think you should also send along a couple of the complete bike. Wow... you mean a Bombadil might come up for sale? That's going to be very tempting to many. Why are you reconsidering your idea for a 1x12 Gus? Sounds like it would have been great -- you'd get all the benefits of a 1x set-up, plus the ability to run the widest tires these bikes can handle. Just curious... Thanks, Ed. You know, that was the first potential solution I thought of, and the one which sent me down the path to discovering what in the world "Boost" was. But I ended up quickly discounting it because it seemed(wrongly it turns out) that running a Boost crank required also running a Boost rear hub. So, essentially it would move my inner chainring outboard by 3mm, correct? If so, and I just learned this, I don't know whether it'd be enough to get the chain to clear the tire. I just measured the chain/tire clearance while in big-big. It is only 3mm. But the big ring in about 6mm outboard of the inner ring. So, if moving the ring out 6mm gives only 3mm of chain clearance, how much will moving the ring out only 3mm, I wonder? 1.5mm? Less? This is definitely a preferable solution(if it works) to shrinking the tire, so thank you for it! But my one concern is the increased chainline differential. I currently have 7mm, and this would make it 10mm. Does anyone know what a sound limit is before getting sub-optimal shifting performance? I'd really love to know. Thanks so much to everyone!
