Just TRIED fitting mine to the swing arm on a titus ftm - PITA! Needed a chunck (about 40mm) cutting out of the front edge to clear the seat tube on full compression. Also needed the "arms" to be 20mm longer so ended up using the long tabs with spacers to push the guard up. To perfect it i could do with 2 rubber wine corks or similar with notches cut out for the gear cable and brake hose.
Anyone use these - pics of the stays etc appreciated, anyone else had similar woes?
