Swapping cogs on a 105 cassette

Postby MinardiM189 » Thu Nov 22, 2012 15:49 pm

I'm looking to change the ratios on my Shimano 105 11-28 cassette, dropping the 11T and inserting a 16T. The only individual cogs I can find are Dura Ace 7900 or 7800 16T. Will either of these be compatible with a 105 cassette? I can get the 7800 cog for just over £5, so not too expensive.

Alternatively does anyone know if it is possible to buy individual 105 cogs?

Thanks, :)

Why not just by a 12-25 instead?

Yes it would be compatible, but you'll need a 12T lock ring too and if you're going at the 105 level anyway you might as well just buy a Tiagra 12-28 or SRAM 12-28.

Thanks for that. I have an old 12T lockring so I'll give it a try with the Dura Ace 7800 cog.

Far cheaper to give this a try than buy a complete cassette, also

Tiagra 12-18 skips 16T and SRAM cassette costs £40+
