Post your drivetrain

Post your drivetrains! List your chainrings, cassette, derailleurs, shifters and tire size. Got a picture? Post that too.

50, 39 & 26 chainrings, 12-32 ten speed cassette, Deore M592 rear derailleur, 105 5603 front derailleur, 105 5603 shifters

Rohloff 14 internal speed....MTB set-up the same...wouldn't have it any other way.    

XTR Trail Pedals \nRotor 3d+ 160mm cranks \nWickworks 44/34 tooth rings \n11-32 force 22 derailleur/cassette/shifters \n

   Campy Centaur 10 speed shifters, Record F. derailleur, Centaur rear.

Sram/Quarq crank 48/38 with Ritchey big ring or Rotor compact crank 48/34.

Campy chain and Sram 11-32 cassette.  Campy derailleur only supposed to work up to 27 cog - wrong.

Jtek shiftmate eliminates the need for Campy freehub wheels and works pretty darn good.  

I was running 32mm Gravel King slicks all year.

Suntour Barcons shift Shimano Deore XT derailleurs. A Suguno 48, 36 & 26 crankset combined with a 13-24 seven speed freewheel. Old-school, but effective;\n\n\n\n\n\n\n

Regarding the Wolf Roadlink, on their site it states that the front chain rings need to be within 14 teeth of each other, and like you, I'm looking at doing the 50/34 with an 11-36, have you noticed any issues with this set up? Currently the bike is being spec'd with 11-32, but I worry for loaded up gravel climbs, that may not be enough gearing. Just want to see how this system is working with Di2? 

Thanks

Eventually I'm going to swap out of the cranks - prolly go Force. Might also go 1x, time will tell...

No issues with the shifting with the 50/34. Pretty sure the reason the reason for the claimed 14 tooth limit is chain tension. To get the chain long enough for a 50frt - 36 rear combination, it is a little slack when in a 34 - 11 combo. I have no reason to be in either a 50-36 or 34-11 combo, but I'd rather have extra slack in the chain when I accidentally go in the 34-11 than rip the derailleur off when I screw up and go in the 50-36.

Perfect, I will have the shop throw one of these into the mix and pick up an 11-36. Thanks for the information!
