Q. Hi, I have a Giant Defy4 from 2010. It is fitted with an SRAM PG850  8 speed 12-26 cassette and a PG850 chain. I see you can get a 11-32 cassette. Is there any benefit fitting this cassette regards hills etc or will it be overkill? Also if I do fit this cassette will I need to extend the chain and by how much?
A. Thanks for your online question, fitting bigger ratio cassette will help with inclines, however this cassette can only be fitted if the bike can work with this cassette, With regards to your bike and mech that is on there a 11-32 would require you to fit a new mech and a new chain and the mech will need to have a bigger cage and the chain will need to be longer. 
Q. Is there any difference between the PG850 12-23 for mountain bikes and the PG850 12-23 for road bikes other than the colour of the smaller cog ?
A. There is only one model of PG850 cassette that will work on both road and mountain bikes with 8-speed drivetrains. The difference between a road and mountain bike would come down more to the ratio used. In most circumstances the 12-23t cassette would be a road bike cassette. Wider ratios such as 11-28t or 11-32t would be considered mtb cassettes.
Q. What is the difference between the 11-28 and the 11-32 and what one would make the bike faster.
A. 11-28 and 11-32 refer to the ratio of the cassette. On both cassettes the smallest cog has 11 teeth, so both offer the same largest gear ratio (hardest gear to pedal). The difference with the two cassettes comes in the low gear range with the 11-32 offering an easier lower gear than the 11-28 cassette. With a wider ratio the spaces between gears will also be slightly wider on the 11-32 cassette.
Q. Is this cassette suitable as a replacement for the Revolution Triad? Is it an upgrade or a downgrade from the one the bike comes with?
A. The Sram PG850 cassette would be suitable replacement for the Triad 2.0. '11. The PG850 would be an upgrade over the HG30 cassette fitted to the bike as standard. The PG850 cassette is drilled to save weight and has a harder wearing satin chrome finish.
