Rival 1 B-Gap adjustment
Hello,
My bike is powered by a SRAM Rival 1 rear derailleur with a 11spd cassette. On the official SRAM manual, they recommend setting the space between guide pulley and biggest cog to 15mm.
However, with proper indexing, shifting is more precise if I set the B-Gap somewhere between 7 and 10mm.
My question is, what are the consequences of a smaller gap ? Bigger chain tension ? premature wear of elements ?
Should I keep my 8mm setting or get back to the "proper" 15mm thing ?
Thank you,

I wouldn't worry about it. If your indexing is working fine at the 8mm gap you have then leave it alone.
Actually,if I am understanding this correctly, increasing the gap to 15mm would effectively be increasing chain tension by pushing your rear mech cage further away from the cassette.
If it ain't broke don't fix it0
