The worst part of buying this? As soon as I was finished installing everything, I realized how much I'd like to upgrade my wheels. I'm thrilled with the performance and bang for my buck this set gave my 26" bike. I have a new 29", but after putting this on the older 26", I find myself splitting time between the two bikes, and sometimes wishing I'd installed this set on the 29". Easier to install than I expected, and very glad I went ahead and purchased this.
My only real gripe is how beat to heck the packaging was. Almost each components box was beat up while the box it was all shipped in was in good shape. Not sure what to make of that. Still, shipped fast, looks great on my rig and everything is what I've wanted. Great power transfer, crisp shifting, and I feel confident as ever. Great setup.
