chain- cassette

[shotojs78]

hi, I have a wheelset with 12-23 cassette and I bought a new wheelset with 12-27 cassette, would I have a problem if I use my 12-27 with my chain (that I use with my 12-23) ????

other than the issue that may arise due to a worn chain with a new cassette.... you may find that the big chainring-27 cog may not work due to chain length. but you shouldn't be in that gear anyway.
