I have bought a replacement FD for an old Shimano Alvio der that is showing signs of wear. The replacement I bought is a Shimano Altus FD-M313 and appeared to be compatible as it was sold as dual pull. However, I now find that the cable clamp is at the front of the pull lever, whereas the Alivio was at the back. There is a cable router at the back to enable the cable to pull the derailleur in the same direction as the Alivio but I am wondering if this will work or if there will be differences in the amount of pull, travel of cage, etc. By finding more online I learn that the Altus is described as top swing and wonder if this is different from top pull. So a bit confused.
