2x10 Drivetrain question on the HD
I love my HD, and the current drivetrain setup is:
2x10 Shimano XT
Double crankset with a 38/26T
Rear cassette is a 11-36
My problem is we have a lot of climbing here, and I would be happy running a 36/24, BUT... Shimano only offers these huge crunching chainrings in the 2x10, and in the 3x10 crankset has something like 40/30/22. I could always do the triple with a bash, but a 30/22 seems kinda silly.
So I'm looking at Raceface and E13, but I'm not sure how compatible they are with the Shimano 10 speed drivetrain.
I tried to do Raceface cranks and a Shimano 10 speed rear cassette on the Ventana, but couldn't get the chainline right. Using a chainguide was the only way I could do that before. I don't want to resort to running a chainguide as a bandaid (and adds resistance to the change).
Would I run into this with the HD too?
Thoughts on my alternatives? My knees most likely will appreciate it.
40/32/24 is the Shimano DynaSys Chainring setup. 32 would run out pretty quickly on the road for myself. On the Trail I can run the 32 on everything.
I have used Raceface Rings on a Sram drivetrain and they worked great.
Nothing wrong with a Triple if your knees are bugging you. I run a triple with a K-Edge Chain Catcher, works great.

This is a pretty cheap buy.

I ran xtr triples, 40/32/24 with a bash replacing big ring and a k-edge chain catcher. Trouble free, never had no issues with shifting. I was using a clutch rear der with it as we'll. Ended up going 1x10, but only for simplicity.
I had the same problem with the 38/26T on my XTR 2x10 crankset - the 26T was way too big a gear for my legs and the hills around here. So I just swapped out the 26T for a Blackspire chainring. It still shifts fine. (I didn't change the 38; sometimes it seems a bit tall, but then there are other times when I like it so I haven't bothered to change it yet. This is actually a bigger jump than the 14T the front derailleur is rated for, but it is working fine. You would be fine with a 38/24T.)

Running the Shimano SLX 2◊10 38-24 with 11-36 in the rear without any issues.
Me running the Shimano XT 2◊10 38-24 with 11-36 in the rear without any issues. My LBS set this up on my wish, I didn't bother with the actual origin of the 24 ring.

ok, wasnt aware of that. however, you can always use some of the cheaper mods to rear cassette than xx1. general lee or one of the others
i actually run 41 cog from ebay with 11-36 cassette. have over 2000 miles on it since this spring, no issues so far. $35 investment.
Running a Sram 3x10 XO crankset with the big ring replaced with a bash guard 22 / 33
Got kinda a crazy combination drivetrain but it works perfect, do use a small spacer on the derailleur though to get precise shifting. Works great with the big ring also but those things only last me a few weeks riding Tahoe before I grind off the teeth.
XO 9 speed shifters
XO 9 speed cassette 11-34
XT 9 speed chain
XT 10 speed front derailleur
XT 10 Speed Rear derailleur
XO 10 speed 3x10 crank with big ring removed.
Sorry about not mentioning the ring I'm using - it's a 22T. So I'm running a 38/22, which is 2 teeth more than Shimano rates the front derailleur but it's working fine. A 38/24 would be perfect.

Since I'm using an XTR double crankset, there is a ring specifically for that because it uses a different spacing. (I hear you can also just add a spacer.) I think you could just use their SuperPro rings Blackspire - SuperPro 104/64 BCD Chainrings | Blackspire, but you would want to make sure that's the right one for your cranks. They are pretty cheap at about $30.
I see you you already have a RaceFace ring; that should work fine, too.
