About How to Adjust the Screw Gap
This step-by-step guide will help you correctly set your Shimano, SRAM, or Campagnolo B-gap tension screw for smooth and precise shifting performance. The B-gap, or derailleur pulley gap, is the distance between the center of the upper jockey wheel (guide pulley) and the center of the cassette’s.
The table below shows the combination of the B-gap for the Shimano 12-speed Dura-Ace, Ultegra, and 105rear derailleur and cassette sizes.
Shimano doesn’t specify the B-gap distance for its 10, 11-speed road groupsets. Instead, according to Shimano, bring the guide pulley as close to the largest sprocket as possible without any turbulence between the pulley and sprocket. The chain.Most B-gap screws are adjusted using a small hex wrench, usually 3mm. Turn the B-gap screw clockwise to increase B-Gap. Turn it counter-clockwise to decrease B-gap. (See B-gap specs for different drivetrains below.) Check how your bike shifts. Re-adjust as necessary.

The B-gap or B-tension screw is located at the very back of your derailleur. It pushes against a tab on your frame’s derailleur hanger, allowing you to adjust the distance between your rear derailleur’s top pulley and the cassette. That distance is your B-gap. If B-gap is correctly adjusted, your.

It did involve learning how to use just a small bit of derailleur cable to hold the derailleur in place while shifting using the adjuster barrel while off the bike. There is no real shifter. Basically I intend to use it as a poor man’s single speed gravel bike off road and a single speed road to.
SRAM makes this plastic tool for adjusting the B-gap on their Eagle derailleurs. My question is, if I want to measure this distance without this tool (say with a caliper instead), how should I go about it? Between which two points should I make the measurement and what's the value I should aim for?.
Derailleurs are fitted with limit screws that stop the derailleur from moving too far inward or too far outward. If you look closely as the derailleur moves, you can see the limit screws stopping the derailleur at each end of it’s travel. The main purpose for the limit screw is to prevent the chain.
