I have a ten year old Norco Alteres - a very nice drop bar hybrid with Shimano gearing - 7 speed. My rear handle bar shifter is wearing out - It no longer down shifts and I have to replace it. My local lbs says that they can not replace 7 speed shifters - Does anyone know what I can use in place of 7 speed shifter, or if something else will work in its place for SIS shifting. Thank you Doug Thomas Welland, Ontario

Replace the worn out shifter with a 9-speed shifter, buy an 11-32 9-speed cassette, discard the 11t cog from the cassette, giving a 12-32, and as 9-speed cogs are more closely spaced than your existing 7-speed cogs, the remaining 8 cogs will fit perfectly on your 7-speed hub. Your existing 7-speed rear derailleur will work perfectly when indexing with a 9-speed cassette and shifter.

p.s. Chain will need replacing as well with a 9-speed chain...

About $120 for the set. But before doing that, Try flushing the guts of the lever out with WD-40. That's given many STI levers a temporary reprieve. If you have bar-ends, just get the 8-speed ones. Their spacing is close enough to work with 7-speed systems.
