This is a mounting bracket and shoe hangers for the Bowflex C6 and Schwinn IC4 spin / exercise bikes. It might fit the newer C7 but I don't have one to test with. The bracket sits in the rear of the saddle mount so if you need the seat adjusted all the way back this will not fit.

Included are four different sets of hangers. Long, short, mixed and angled long. The short pegs are for using the loops at the back of the heel. The bracket is very firm to snap into position. You can glue the hangers to the bracket but I found it not necessary.

No supports needed. I printed in 3 wall & 20% fill with PLA and it seems overkill.
