Thanks for the followup. My S-bar arrived last week and I am about to place an order online for Ergon GR2s. I understand the "plastic wedge" issue that you pointed out and this is the reason I am still wondering if I should order the shorter "grip shift" version of the GR2s. However I might just get the regular version, try them out, then cut off an inch or so from the inside if it interferes with shifting.
