Shimano Dyna-Sys

If you haven't taken a look at the new Shimano Dyna-sys XT and SLX systems, it's about time you did.  I've been doing a little homework lately, and I'm pretty impressed with the new changes - I'll for sure have it on my bike next year.  I've always ridden XT components for their affordability, durability, and performance.  I don't think you can beat it for the price, plus, if I smash a large ring on a ride I don't have to take out a second mortgage on my house to replace it.  For whatever reason, Shimano chose only to run XT and SLX with the new Dyna-Sys (I think they'll be unveiling a new electronic XTR soon...just a guess).  Anyway, the changes look like they'll really improve mountain bike shifting.  First, they chose to keep a triple crank upfront...good for those of us who like to climb steep, technical rides like Beus, Malan's, or the Indian trail.  The rings are now closer together for a faster, more seamless shift.  They also lessened the gap between each ring by making the small cog two teeth larger (24t) and the large ring two teeth smaller (42t).  The middle cassette rings have a smaller incremental change between each cog than previously for smoother shifting and less dramatic shifts, and comes in an 11-36 option.  The goal is to make it possible to ride on larger rings more frequently to lower overall chain tension and decrease impact on rear suspension systems.  You should get an overall longer lasting, better shifting drivetrain that improves full-suspension designs.  The chain is the first 10s designed specifically for mountain riding.  It sheds mud better and is more durable.  Another cool feature is that it's directional.  Right side outer plates are designed different from left inner plates for fast, smooth shifting front and rear.  All-in-all, I'm excited to get out on the new Dyna-Sys to give it a whirl.  We'll be getting product in soon...call us with questions.
