Hi everyone,

The thump button (the one that upshifts the rear mech) on my TT specific shifters of the v2 EPS gets sticky (does not return after the click).

As a result the rear mech shifts the chain all the way up to the biggest cog.

I opened the 2 screws, removed the cover and lubed the spring and sliding surfaces but no luck.

Any ideas?
