Best Racing Gravel Bike 2024

On the market for a gravel racing rig, and likely will opt for a Factor OSTRO Gravel.

Is anyone running 1x with a Power2Max? I’m trying to understand if there should be any issue running Rotor aldhu cranks (110 bcd) with a P2M and a single chainring with GRX in the back. Can’t seem to find anything conclusive.

Sorry, I’m taking the chance to laugh a little that right after I joke about expensive bikes the Ostro is the next one brought up :laughing:

Yes this will work fine.

I ran 38 Gravel King SS+ at unbound and they were fine, but looking back (mud aside) I think I would have been better/faster on wider tires (Domane could only fit 38s).

I did manage to snag an entry in Big Sugar 50 and I am going to run 47 Pathfinder Pros (will install and test this weekend) on my new Crux. I rode 38s in Ark gravel and it was really horrible.

For Big Sugar 50, is it worth running aero bars? The course profile seems to indicate there is a lot of payved road on the course…

While I do agree up to a certain point, having raced plenty on a steel hard tail, as well as mid level road carbon, and later moving to higher end carbon frames in both disciplines - the difference is there, marginal or more, but it’s there (be it due to frame material, geo, aero, etc) if we’re comparing race rigs level.
But that’s my personal opinion, per what I felt.

Worst case - I’ll sell it :slight_smile:

And thanks for confirming!

I have on my Lauf Seigla Power2max NGeco with Rotor Vegast cranks which have same the axle interface as Aldhu cranks I think. I had to buy a offset axle which fits the wider 73 mm BB on Seigla, but on a normal BB no mods should be needed. That spider is for 110 BCD Shimano chainrings, so I put a Wolf Tooth 46T GRX Drop-Stop B chainring on it. It didn’t fit at first because of the profile to fit on GRX cranks, but with some filing (a half mm or so) it fits perfectly and works great with SRAM Transmission at the back on my bike.

I really like my ostro gravel. I am running a 46x33 red crank no issues. Good luck on your search

I’m a road biker looking at buying my first gravel bike and I live in Colorado. Planning to ride it in events like steamboat and unbound, as well as on some of the usual gravel roads around the mountains here (fire roads, etc). I’m looking at the usual suspects: the Aspero-5, kaius, crux, checkpoint, and potentially the Enve. Does my use case standout for/against any of them in particular? Road manners aren’t super important since I have a road bike for that.

I think the Aspero is the only one that can’t officially clear at least a 44mm tire.

If money is an option I’d take a look at the Giant Revolt…seems like a great bargain compared to the bikes you listed.

Checkpoint can clear 45mm

Love my Checkpoint, no complaints. Haven’t ridden any of the others. The down tube storage is super useful as well.

If you are going to limit your riding to smooth gravel like fire roads and SBT, AND want the fastest bike consider the Kaius and Factor Ostro. If you want to venture into the chunkier gravel the Colorado Rockies have to offer, you want 47-50mm tires and the Enve is your rig. It rides magnificently.

  • Progressive Geometry (fast!)
  • Downtube Storage
  • Nicely concealed cables (unlike the checkpoint)
  • 50mm tire clearance.

No other bike offers this package. The closest is the checkpoint, but the ride is too sedated and the cable integration is not well executed.

Huh? Not sure what more you need/want…

Thanks! I can add it but it feels like the list is getting very long!

I think a decent number of people have said the Aspero can clear 45mm tires in practice, so that’s why it’s on the list.

It’s definitely on the list for this reason, and it seems like a nice compromise. Just annoying that it doesn’t come prebuilt with a SRAM AXS setup.

Would you say the checkpoint comes closest to this type of package?

I can confirm that I ran Maxxis Rambler 45’s (with inserts) at Big Sugar last year with no issues.

Honestly, I never even thought about clearance issues when I bought and installed them, so never bothered to check clearance, but I also never had any problems.

I do not want to see cables.

Yes. If concealed cables are important. But perhaps the Diverge or the new Stigmata (w/o fork) might be closer. It just depends what aspects are non negotiable for you. For me, exposed cables in 2023 is non negotiable, but the Trek solution doesn’t quite do it for me. Another advantage of the MOG is the UDH if you want to run Transmission. I can confirm it shifts like heaven.

I picked up the 2021 Revolt and so far it’s real nice. Checks all the boxes for me coming from a RaceMax.


I’m sitting here looking at an Aspero 5 with 38’s on it. If I was going to run 45’s, I’d say the rims would need to be wide, probably >25 inner and my concern would be clearance at the seat tube.
