I'm currently running an 8 spd. 12-25 Sora cassette with my Shimano 105 rear wheel. This is a Road bike. Problem is that this casette is pure steel and very heavy. Also I'll be doing a lot of hills and mountains for training this spring and would like to fit an SRAM 8 spd. 11-28. The exact model is SRAM 5.0(11-28) unfortunately it does not mention if its for Road or MTB. Can anyone let me know if the Shimano 105 rear wheel will accept an 11t top gear or if this set-up is even compatible? I want to make sure its compatible before I buy the cassette. Looking for some feedback, thanks.

It will fit on the hub and the spacing is the same. Your problem is that you may be beyond the maximum tooth capacity of both your front and rear derailluers. Something that may help is if your running a 42 tooth small ring on the crank, get a 39 tooth.

Large cog spec on the sora DR is 27,but it will easily shift a 28. The cassette has nothing to do front derailer capacity.
Why would you want an 11 tooth??Alexx

...unless you have a 42-tooth big ring? An 11 tooth cog is about the most useless thing available.

I emailed Sheldon Brown about this last night, lo & behold he had an answer ready for me the next morning. My hats off to Sheldon and he really knows he's stuff.

BTW: I'm running an Ultegra 53/39 and a Tiagra Long cage Rear derailleur.

He said that the SRAM 11x28 will work just fine, however he doesn't like the way it shifts nor the 11t cog. He suggested the XTR 12-28. Awesome advice! Sigh, too bad I can't afford it.
