Best Racing Gravel Bike 2024

Time has come for me to get a proper gravel racing bike, no budget constraints really. The bike will have to serve as ocasional road bike.

Here’s the rank:

  1. BMC Kaius 01 [CT Review] [CN Review]
  2. Factor Gravel Ostro [CM Review]
  3. Scott Addict Gravel Tuned [GFM Review]
  4. Specialized Crux S-Works
  5. Cervelo Aspero 5
  6. Enve MOG
  7. Trek Checkpoint SLR9
  8. Canyon Grail CFR

Which bike am I missing? Any feedback on the bikes in the list?

Cervelo Aspero would be on my list . Aero frame makes sense for racing.


+1….sounds like it would be a great fit for your needs (gravel plus occasional road rides). It is basically a gravel bike for roadies.


Something to consider that Dylan Johnson has been mentioning lately, is that he feels the industry is lagging behind in figuring out the wider tires are faster for gravel. He mentioned getting someone to buy and send him 47C Pathfinders from Canada as he couldn’t get them and it was his intention to use them for racing in 2023. He also ended up racing his Factor HT MTB with drop bars, rigid fork and Conti Race Kings (2.2 I think) after testing it back to back with his gravel bike and finding the MTB drop bar build was faster overall for one of the races (maybe Big Sugar?).

I think if I was to buy a new gravel bike I would want something that could accommodate at least a 45c tire, which may help weed out some potentials.

This would disqualify the Aspero and the Kaius but I believe the others you listed can at least handle a 45c. Some others to consider could be the Lauf Seigla Rigid, 3T Exploro Ultra and the Canyon Grizl.

My current bike maxes out at 42c and I’ve never ridden anything but 40c with it and do ride blue level single track with it (fully rigid) but don’t doubt the idea that, to a point bigger may be bigger with may moving to 30c on road now, my winter road build is 32c.

I won’t be shopping for a gravel bike till 2025-26, (new road race bike planned for 2024) but when I do I will be looking for big tire clearance but something that is still suitable for CX (my current gravel bike serves as a winter road machine and races gravel and CX with a couple sets of wheels) I think some of the more exaggerated gravel rigs are getting a bit long and a bit too slack to navigate between the tape effectively or it may come down to needing a separate CX and gravel bike.


If you’re just interested in expanding your list, I would suggest Allied and Open Cycle.


Factor Ostro Gravel or Factor LS would be two bikes to consider. I ride a Factor ONE road bike, any I’m good friends with my mechanic who sells the bikes. I’ve gotten the chance to ride both the Ostro Gravel and the LS a few times, and I can barely tell a difference from my road bike to be honest. I also owned a Crux for a while, and although I really liked that bike, I would never choose it over an LS.


The Aspero is a nice bike, kanzo fast is nice if your ok with 1X, factor ostro gravel, bmc gravel bike, crux is light. I’m intrigued by the new rodeo it looks like it can take a wide tire

I have and love, no complaints.

As above - Factor Ostro Gravel should be on the list. Pretty much same measurements / fit as the Ostro VAM, except modified to fit 45c tires.

They just released new bars / aero bar combo too.


Aspero takes most 45s with plenty of clearance, unless the race is in sticky mud where you need all the clearance you can get.


Re: Factor Ostro

Several posters mention it, however not a single owner. I guess the hook is the price, Its 5k cheaper than the other bikes in the list. It’s hard to find the specifications of the premium build

For some reason I don’t see myself spending this kind of money for a Factor bike. I guess it’s mostly familiarity with the brand.

From what I have read online, both can fit 45mm tires and yes, it’s a requirement for me.

Thanks!. These are very fine bikes, but I wouldn’t consider them in the top 5.

Could you please elaborate?

Could you describe the “character” of the bike, ride quality, etc.?. Thanks

Trying to make the same decision myself. Currently looking at the checkpoint and the aspero. Leaning more toward the Aspero.


How did you narrow it down?. Did you consider the Kaius 01, Crux and Addict?. If no, why not?. If yes, what drove you away for them? Thanks

Aspero can handle 45’s just fine……


I’d definitely add the Factor Ostro Gravel to the list. Especially with the new aero bar they just released and the ease of adding TT extensions to it. And the price isn’t bad. Not sure why you’d be hesitant with Factor, they make really nice bikes and equipment. I ride a Tarmac SL7 now, but if I was buying a new bike the Ostro VAM would be high on the list.

The BMC would be up there on my list as well. Such a beautiful bike. And the tire clearance should suit 95% of riders. There aren’t too many races you’d need any bigger. Not if you’re trying to go fast.

I have a Specialized Crux and it’s a great bike. But, if you just want a gravel racing machine, I think there are better bikes. I use mine mostly for cross, and bought it as a jack of all trades kind of bike. So with that, you get a master of none situation. I’m by no means pushing my bikes to the limit, so it fits me fine. I wanted exposed cables because like I said, it’s mostly a cross bike, and I don’t see the benefit of full integration. But if you want aero, there are the bikes listed above that’ll get you hidden cables. The Crux is super light, which is great when you’re picking the bike up a lot for cross, less needed for long gravel races. With road wheels it’s the same weight as my Tarmac.

Hope that helps.


The problem with his testing is that he rides only certain sections of the gravel (usually rougher sections) and then extrapolated those results to the entire course.

The question needs to be whether a particular setup is faster over the whole course, not just a few sections.


Just going from what the brands themselves say spec wise, from Cervelo

"We designed Aspero to fit most 700c x 42mm or 650b x 49mm wheel/tire combinations. Of course, there are variables—rim width, tire casing, and tread depth—which will affect final clearance. We (and the International Organization for Standardization, or ISO), always recommend 4mm of clearance between the tire and frame.

**New Shimano road (not gravel) 12 speed front derailleurs reduce tire clearance in the rear of the frame to 700x38c or 650x45b."

I expect most under estimate the actual tire size they can accommodate as if running wheels with wider inner widths they can over inflate slightly and to allow for some mud clearance, in some cases, like unbound it wouldn’t matter what mud clearance you had but I think in general, to prevent you from wearing out your frame prematurely brands factor in a certain amount of mud clearance when suggesting the max tire size they can handle.

The new Ventum GS1 seems to fit in this list as well.

It might, but to keep it practical I’ll focus on Top 5, I don’t see the Ventum above any bike in the current top 5.
