One of the nice things about Shimano and SRAM updating their high end parts relatively often is that the new technology generally trickles down to the lower end groups as well. In recent years it seems like more and more of the lower groups are reaping the benefits of the new technology leading to some great drivetrain and braking parts for a lot less money. The weight may be a little bit more than the top end groups but usually the functionality is really close. Grams Light Bikes found this out first hand as they reviewed Shimano’s SLX group. They were impressed with the performance of the drivetrain and most notably the brakes. Check out the thorough review for all the details.
