2012 Specialized SHIV Comp Rival

I don't know much about the Specialized Ruby but I can tell you about the Shiv in general. I ride a 2012 Cannondale CAAD8 alloy road bike and I have a 2014 Specialized Shiv. Comparing my two bikes, here is what I can tell you.

1. Weight. The Shiv is heavier than my alloy bike, at least 3 lbs heavier. This help the Shiv remain very stable at speed and carry a lot of momentum downhill. But the Shiv is a pain to climb with.

2. Visibilty. The Shiv sits lower than my alloy bike. This improves handling and probably increases some speed.

3. Position. The Shiv takes a long time to get used to. Going from a road bike to the Shiv has a steep learning curve.

4. Stability. The Shiv feels solid as a rock rolling down the street. I never managed to remain stable using clip-on aerobars on my road bike but I don't have that problem with the Shiv.

Personally, I say it is totally worth it because the Shiv is a riot to ride. Keep your Ruby for group rides, mountain climbs and day to day riding.

The Shiv is a great bike, but the fit is kind of funky... I'm guessing from your post that you're looking to get a bike to help you with the bike. Since the rider accounts for the vast majority of the drag, you will only get faster if you can maintain a good position while generating power. This is why you should ALWAYS start with a bike fit, then start looking for bikes that fits YOU. The Shiv may work, or it might be horrible for you...

I have a 2013 Comp and love it. I am long legged with short torso so needed a shorter reach. Do research and/or get fit. I have not had any issues with seat post and recently ran Di2 which was a bit of a pain but otherwise great bike.
