Hey guys I usally post in the ss/fg forum but I am leaning toward the road bike community as I am going to purchase a caad 10 in the next days

the only probleme I can not decide between the caad10 4 SRAM rival or the caad 10 3 Ultegra

Prices are really good as I can have both in staff deal differences between the two is a hundred dollar

I test drove the shimano 105 and the rival to have an idea on how they shift

I think it's a wash. Pick the one you like the best based on the color of the frames. If you are new to road bike brifters then you will like either one (Sram/Shimano).

Go Sram man. You will love it. Plus it is cheaper, and lighter.

personal preference.

the only major negatives i've heard about sram is that the front derailleur has to be set perfectly to work well.

I'd go ultegra, but only because I've been using exclusively shimano components since my first real bike.

If after testing 105 and Rival bikes you have no preference, then I'd choose based on which hoods fit your hands better.

Go by hood ergonomics and color scheme if you don't have a preference for either STI or Doubletap shifting. Or if you don't care about those things and prefer to save a few bucks, get the less expensive one... Either way, enjoy it and remember to post pics when you get the bike!!!

Hmm these are what I would keep in mind:

- Which brand components am I most familiar with (for me, Shimano)
- Which one better has better ergonomics
- Which one has a better wheelset, saddle, cockpit, etc...
- Am I going to upgrade components?
- If yes, then it will depend on my favorite frame color.

A lot of it will be up to you. But the CAAD10 frame in general is a stellar frame, you'll love it.

I did test ride the shimano for about 25 km the sram rival only about 7km, because of the bad temperature and the rain i f i remember at this moment it's seems sram shifting is a bit more rough in the front then shimano but like I said maybe with more mile I would be comfortable with sram and I like the aesthetics of sram

I would be only upgrading the wheels if i had two in a season or two because in the end I want to participate in some few events and even races

Id take the one with the best cranks and wheelset. This 2 are the places most manufacturers cheapen bikes

I have no problems on two different Rival bikes. Of course, mine might be set perfectly.

OP, buy the one you like best whatever that criteria is for you - be it color, shape of hoods, etc.

I've never heard that about a Sram FD, nor have I experienced any difficulty. I've built up bikes myself with both Shimano and Sram and they are 100% identical as far as ease of setup and maintenance. If either bike has a better crankset, go with that one. The quality of the chainrings will make a much larger difference on the performance of the drivetrain than anything else will since you're comparing two quality products. Also, check out if either comes with better brakes, though I believe both come with Tektro.

If all else is equal, go with the purdier one.

The Ultegra bike has the C2 seatpost (C2 seatpost is carbon C3 is aluminum wrapped in carbon) but both have C3 handlebars. Obviously the cranks are different but depending on who you talk to either one is better. The SLK light on the untegra bike is really nice. Also the brakes are much better on the Ultegra bike as the Rival bike has generic Sram brakes not the rival line. Kind of like how the 105 version has tektro brakes and not 105 brakes(I have the '12 10-5). Just upgrading the pads alone would fix that to an extent.


Also wheels are are about the same level on both. Not stellar but easily can upgrade later to somehting like the Boyd Vitesse wheels and sell your stock ones for $100-200.

My C2 is also carbon wrapped aluminum. It's from '09 so maybe it's different now.

Why is SRAM both cheaper AND lighter? I thought lighter should be more expensive?

Completely different brands man. Apples to oranges, different engineering/technology. Within Sram, the lighter you go, the more expensive. The same thing with Shimano. But just because sram is lighter than shimano, doesn't mean it is more expensive. If that was the case, Apex would be cheaper than Ultegra.

Kind of annoyed they keep dropping the specs. My 2010 caad9-4 came with the C2 carbon post, C2 stem, and Force cranks. Now the 10-4 has the C3 stem and C3 carbon-wrapped post and a lower level crank. Plus it costs more. Guess that's just part of the whole rising costs issues across the industry and everything else.

I would pick Shimano because I like the shifters better. Double tap only allows shifting one gear down at a time per throw, whereas Shimano allows 2 or 3 depending on the generation of shifter.

In the real world, this might not matter, although I am used to Shimano, and so it'd be a strange transition to move to SRAM.

I do not think that there are any quality differences at all, so it really comes down to preference (and weight as mentioned above)

^yeah...not true.

So I take it that you've never used a SRAM shifter before.

Other than playing with it to observe its operation, no.

If I rode SRAM, I think that I would either learn to love or hate the double tap design.

I really like the fact that it would be easier for me to reach the shift mechanism from the drops/sprinting position with my shorter fingers, maybe enough to negate the other differences.

Like I said, it's preference.

Isn't he correct about the shifting down (smaller cogs) though. I've never figured out how to drop two cogs at once. If it's possible, please let me know. However, it's easy to click several times so I don't see it as an issue. However, shifting up (larger cogs) you can jump at least three. Not sure I've tired more than that.

your terminology is bass-ackwards by most standards.

shifting down to most people means fewer gear inches-- an easier gear to pedal. sram can go down 3 gears in the rear in one swoop if you push inward as far as the lever goes, 4 clicks.

shifting up to most people means more gear inches and harder to pedal. sram can only go up 1 gear per lever press, but you can push it in rapid succession or even multiple times before you pedal and voila! you've gone up 2-3 gears really fast.

Fair enough. However, I was just trying to clarify what was said. Most casual riders have no clue what a gear inch is and shifting "down" the cassette is a logical explanation for some since you go down from larger to smaller cogs.

lol, apex is cheaper than ultegra...
