Okay. I very much dislike when someone asks a question, and never updates a thread when they find an answer.
So to restate my issue: I ordered a set of bumpers and grommets for the Tecnifibre TFlight 300 XTC. The bumper and grommet set did not come with the EZ Lock Eyelets. (pictured below)
I contacted TW support and inquired if my pack was missing the eyelets, or if they were never intended to come with them. Internet research, mostly consisting of tennis talk and reddit, suggested conflicting information. Some said that the eyelets were supposed to be included with the B&G set. Others said that the eyelets are not included with the B&G set. Technifibre, to my knowledge, does not sell the eyelets individually.
So I'm thinking "What's the point of selling a B&G kit that doesn't have all the parts that you need?"
The reflection on the bag makes it challenging to see, but you can see how the grommets line up with the EZ Lock eyelets.
Well, I decided to Cowboy on (username checks out) and see what happens. I pulled the original bumper off, and the EZ Lock Eyelets on the frame stayed in place.
I only replaced the bumper, as it was worn through and down to the frame. Otherwise, the grommets look fine. I'm just going to keep the remaining grommets on hand in case the others start to show wear.
In short, if you order a bumper and grommet set, and you don't get the EZ Lock Eyelets, you can still replace the other grommets. Just pry the old ones out (being careful not to damage the frame) and press the new ones in.
