Will my 105 rear mech take a 28T sprocket?
edited December 2009
Hope you can help. I've got a Shimano 105 rear mech. I'm guessing these are short cage... (a question more than a statement)
Are these compatible with a 12-28T rear cassette?
If not, I've just wasted some money. Doh!
Should manage it. Just make sure the chain is the right length.
I like bikes...
tweak the tension screw if the top jockey is rubbing
ability to handle 28t is not linked to cage length but the geometry of the mech itself. In other words, a long cage road mech isn't like a mtb mech. Mtb mechs can handle bigger sprockets than road mechs because they have different geometries, which hold the jockeys further away from the sprockets
Facts are meaningless, you can use facts to prove anything that's remotely true!
giant scr1's came with 105 and 28 and work fine
Yes, just done it. Used a 28-11 Deore cassette
Genesis Croix de Fer - my new commuting mount
Saracen Hytrail - the workhorse - now pensioned off
Kinetic-One FK1 roadie - the fast one - hairy legs though!
Cannondale Jekyll Lefty MTB - the muddy one which keeps tipping me into gorse bushes!
I decided to get a medium cage mech, the old short cage one can go on a bike I'm making up for a turbo trainer I possibly may only look at. You know it makes sense....
