I am starting a conversion of a MTB to a touring bike. It is a 7 speed which currently has Altus components. Going to try to upgrade to Deore 7 speed. Can't seem to find indexing bar ends for a 7 speed so will any friction bar end shifter work? Does it have to Shimano or just any brand? May not be an issue as I may go with trekking bars and thumb shifters, just looking at my options if I go with drops.
Thanks for the help.
