Do you think rival 22 will be adequate as Force seems pricey?
Absolutely, I have rival. Have a read of some reviews. Everyone says it functions as if it were the Red series, the difference is weight and of course materials used. I personally can't believe that people would choose shimano over SRAM.
Here's a list of what I like about it:
- Double tap, it's so intuitive. You press once for a change up, press once, twice for a change down. You can even press fully across to the left to change down 2 gears. As for changing up, it's like rapid fire on a MTB. Extremely accurate and fast shifting.
- Shifters are not part of the brake, they're proper paddles which can be moved totally independently.
- Adjustment - so easy, just 2 Allen keys and 20 seconds later the shifter is moved.
- Noise. Not to everyone's taste, but when you change up (especially) you get a very satisfying and slick thump/click. It's quite a mechanical feeling and noise. I love it.
- Yaw front dérailleur is so worth it, no more trimming on the shifters. The FD yaws to accommodate the chain on any gear and in any combination. Marvellous when you're happy spinning the big ring in a not so ideal gear combination.
The only notable difference I could find that I didn't like at first was the width of the hood. They're slightly slimmer than shimano. But that takes all of 10 minutes to get accustomed to.
Genuinely, a good/great groupset. And happily sits between 105 and Ultegra in pricing. Functionality in shimano terms is roughly between 105 and Ultegra, however many believe it to be on par with Ultegra.
Try to find a bike with it on and have a poodle about.
Ps. Sorry for the long post.
