Bought two these to replace saddles on a MTB and Cyclocross bike and replace grips on two MTB's. While the MTB grips are a bit annoying becuase of the fin on the inside end of the grip, they work well and the locking pieces work well. I eventually had to cut the fins off with an exacto knife! It might affect durability, but we'll see.
The saddles are comfortable for most rides, even forest road or shorter road rides if you need them for that. Just make sure you are wearing good shorts if you'll be on the seat for more than 30 miles. The sides don't rub on my legs and it looks good on the bike. All in all, it's an awesome deal if you can take the small tradeoffs!
