Howdy gang, I've had the 11-36 cassette sitting on the shelf for awhile and the prospect of my first gravel event (Morganzo 55) finally motivated me to put it on. Stock is 11-32 and that's what the rear derailleur is rated for but others have used an 11-36 on my bike. I can pedal with the chain on the 36 as chain tension keeps the upper derailleur pulley clear of it but if I back pedal, it interferes. I know a Wolf Tooth Roadlink would give me the clearance but I don't have time to get one ( I will order one though). I can shift into the big big combo (50/36) so I have plenty of chain.
I'm wondering - if I remove a link or two, will the increase in tension on the derailleur spring result in more clearance between the pulley and the cog?
An added question - is there a trick to getting the speed links to release?
1. Have you lengthened the chain? Too short can cause problems.\n\n2. Have you run the B-tension screw all the way in? You may need to reverse it to have the pulley clear the cog.\n\nI have a 105 long cage RD with 44/30 rings, 11-34 rear. Have run 11-36 with no adjustments.

I used a new SRAM 1130 chain which was one link longer than the chain I took off. It will shift onto the big ring (50) big cog (36) with a small amount of tension still in the derailleur (the chain is not absolutely straight through the pulleys but not far off) so is long enough as I understand it.

The B-tension screw is all the way in. Reverse the B-tension screw? So I screw it in the bottom. Does that use the extra length of the screw head to effectively lengthen the screw?
I took it for a ride yesterday and it worked fine. I avoided back pedaling in that gear but even if I needed to it would only be for a partial revolution so shouldn't be a big deal until I get the Roadlink.
