I replaced the Tektro calipers on my Wife's bicycle with Shimano 105 BR-R7000 calipers. She already had Shimano 105 levers.

When I went to fix the cables in the new calipers, I discovered that the cable-end ferrules did not fit into the cable adjustment barrels on the calipers. Rather than a round receptacle the BR-R7000s have a square entry into the adjustment barrel. I had to strip off the cable-end errules and insert the cable housing without them.

Does this make sense? Anyone else experience this? Any downside to using the cable ends without ferrules?

No. That won't be possible and I believe these to be standard dia cable housings with very thin ferrules. Seems the square entry point of the caliper's adjusting barrel is the cause.

Measured and cable housing is the standard 5mm. O.D. of end cap ferrules is 5.6mm. I am finding multiple references for Shimano calipers to not require end ferrules whereas SRAM brake calipers do require ferrules.

Just recalled that I got my answer to this question years ago when changing out from a FSA caliper to a Shimano caliper. NO FERRULES.

Please forgive the age-related redundancy!

What caused my confusion is that the cables came out of the Tektro calipers with ferrules on. Caused me the same confusion 4 years ago when pulling them out of FSA calipers with ferrules also.
