Going from Road Bike to Gravel Bike - Need Help on groupset choice

Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like : "Unbround Gravel".

Going from Road Bike to Gravel Bike - Need Help on groupset choice

I have been riding a Specialized Allez for about 11 years now that has a Shimano 105 groupset (with the exception of the rim brakes which are some Specialized branded brakes). A couple of years back, I switched out the original cassette for different gearing a switched out the rear derailleur for a newer long-cage Shimano 105 at that time.

I am trying to decide between a Specialized Diverge Sport (with 105) and the Specialized Diverge Comp (with Ultegra). The price difference between the two is $950.00. Thoughts and opinions on which route to take are appreciated. Is it worth it on a gravel bike to spring for the more expensive Ultegra. Appears there is no difference in the wheelset between the two. Looks like you get an S-Works seatpost with the Comp, so I guess not all of the cost increase is attributable to Ultegra.

Do you have a link for each bike you're looking at?

If they're the current models then I'd go for the Sport, it's a way better value.

The above 5 bikes are currently listed on Specialized's website as being Comp or Sport with 105 or Ultegra drivetrains.
I assume you are referring to the Diverge Sport at $2800 and the Diverge Comp at $3750?

Looks like the differences are Ultegra vs 105 shifting, Zayante vs Alba crank, saddle is different, and tires are different.
Who cares about the saddle difference- thats something many people change anyways and if one fits better in the shop, im sure they would swap and adjust accordingly to make the sale.
Tires are something that many have preferences on, so that isnt a place I could comment, especially since I dont buy Specialized stuff and have no experience with their branded tires.
- Ultegra vs 105. There is a weight benefit to Ultegra. Thats it. Both will shift reliably, stop reliably, and last just as long as the other. The weight penalty is negligible(to me).
- Zayante vs Alba. There is a weight benefit to Zayante. Thats it. Same chaninrings on both. The weight penalty is something like 80g, which is about what bar tape weighs.





A Zayante costs $25 more than an Alba crank. I dont think the tires and groupset tier jump justify $950 in cost. But Ultegra is really nice(i have some of it on road bikes and my gravel bike). I also have 11sp 105 on a road bike and it works great. None of this stuff is bad at this price point.

...and the Specialized site deserves a special section in Hell for being so confusing. Why are there so many versions of the Diverge and so many web pages for the two bikes you are asking about?!?

i would wait for specialized to update the future-shock on the diverge before buying, the 2020 Roubaix came with new future-shock with hydraulic damping

I'm starting to think $2800+ for 105 hydro and carbon is our new norm. At least from the big guys.

I'm guessing because one SKU is MY2020 and the other is MY2019 nd one is 2018, based on SKU

Carbon fiber with 105 and Ultegra...is now that expensive. Even Salsa has 105 builds that ping $3000

For the differences listed here, I but save your money and get 105.

Very true. Thatís why I pulled the trigger on a 2019 Niner RDO RLT 9 for $2800 with full Ultegra.

The direction the groupset is moving towards is about the crankset. In the near future or even now we see a single ring coupled with a wide range in the back cassette.

Its going to be which version: Ultegra, etc. will make it work. SRAM is way ahead of the game, even ahead of Shimano as some wrenches would say.

Are you saying road groupsets are going to 1x and all the current 2x groups will soon be obsolete?
I am not sure why 2x and 1x cant co-exist. There are people who prefer both, and there is riding that is good for both.
SRAM has been ahead of Shimano on drop bar 1x for sure, but the Shimano GRX group has a 1x option and that will allow people to have 1x group brand options.
Given the recent and current Shimano releases that are drop bar 2x, I dont understand how that setup will be gone in the near future.

I ride both road and gravel bikes with 105, compact 50/34. Only difference is, the Motobecane gravel bike has a Gossamer FSA crank instead of Shimano 105 crank on Domane S5. It was easy to hit the ground running on the gravel bike.

IMO, upgrading to 105 bikes from bikes with lesser groupsets is like going from standard definition TV to high definition TV. Major upgrade.

Not necessarily obsolete for everyone. Just the direction. The gravel riders who still ride mostly on paved roads versus the others who dedicate their gravel bikes to mostly gravel and at the same time, their road bikes to the road when riding in a group.

Is it a "big direction", one that could have been predicted and that the manufacturers are already making adjustments? They are.

Interesting.
I still see a lot of 2x on gravel bikes around me. 1x is certainly seen too. Doesnt seem like either is going anywhere anytime soon here.

As for what Shimano road group will get 1x first- GRX exists, so Ill say that GRX will be the one.

1x is somewhat a fad in this application.

Mountain bikes need 1x to remove constraints on frame design and suspension

I could make a weak argument for cross, as I never spin out my small chain ring on cross.

But for gravel/road it really does nothing. Chain retention shouldn’t be an issue on well designed/speced bike. Adding a monster cassette isn’t going to save you the weight of losing one chain ring. If I’m running with the testosterone laced crowd, we may be doing some 35mph sprints which drop the 1x people (prompting a regroup).

There is nothing wrong with 1x for many people. It looks kinda cool, and may be less confusing for some people, but its not going to meet everyone’s needs.

I just went through the same decision. I decided on the 105 group. I built up a set of 700c and 650b wheels for it but the DT Swiss set that it came with are not at all bad.
