Hi there.

I put Interupter levers on an MTB Drop bar bike with cantilever brakes and now drop bar levers feel spongy. The interrupter levers feel fine. Any ideas why the two different types of brake levers feel so different? I did NOT have this problem when I did the same thing to my touring bike also with cantilever brake calipers.


Assuming the main levers are not bent/damaged/corroded, you
have a cable (wire or casing or ferrule) problem between the
main lever and your add-in lever.

One common problem is a too-short casing which seems sorta
OK until the handlebar tape is wrapped.
