Yes, the AEOL Pro 37 are good sets of wheels, fast, I put them on my 2020 Domane SL 5 and wow the bike now weighs 2 lbs less (from front and back wheels vs OEM Affinity) using 28c Continental Gator Skin. They work great. Was going to put the Pro 37 on my 2015 Domane 4.5 (Front has 15mm shaft/scewer), of course it won't fit (store is calling Trek Wisconsin to see if they have 12mm end cap and skewers/shaft retrofit). The AEOL Pro 37 and the AEOL Pro 3 both have 12mm through end cap (front and rear). The AEOL Pro 37 rear wheel works fine (Domane 4.5 has 12mm rear wheel shaft), fits nicely. BTW, with that said, I really like the AEOL Pro 3V, it has 25mm inside wheel width (clincher). When I put 28c Continental Gator skin on it, it makes the 28c a little wider (into a 31.5mm )!!! Still retain the 28c fast rolling (at apparent 31.5 mm width) and gives a little more confidence on cornering sand laden and gravel bike paths (Santa Monica, Manhattan Beach CA). Another BTW, the Pro 3V turns the 32c continental gator skin into a whopping 35.5mm (will let you know after a few hundred miles using AEOLUS Pro 3V with 32c tires - apparent 35.5 mm when measured). Is the 35.5 mm too wide and potentially eating more wattages? Riding 20 miles tests each with AEOLUS Pro 3V with 32c versus AEOLUS Pro 37 with 28c indicated no difference in speed. Not statistic significantly different. So, for now, I'll be using the AEOLUS Pro 37 with 32c tires: Soft on the road, retaining fast rolling, grippy on the corner and capable of Gravel with cushion ride feel.

Nat S. Interesting info, thanks. I also have an Emonda ALR 4 and might consider putting the Pro 37s on that and then get the 37v/32 tyres for my Domane. Lots to consider. I’d appreciate your thoughts as you try out your various set ups.

Does the hub make a clicking sound?

@@17melee No. It’s unbelievably quiet.

@@mikebrown600 you can upgrade from the 18 teeth to like 48 teeth ratchet and that should make it louder. I haven’t done it yet, but will order the 51’s in a few months. Covid still has stuff jacked so won’t get them until next year riding season anyway.

Sweet, these are really impressive for the price

Jamesthebikeguy Cool. I get them fitted early Sept. I’ll let you know how they ride.

Glad you enjoyed it!

Would you still recommend these?

Enjoy!

Can you tell me what is the difference between pro 3 and pro 37? I am very curious about it and i can not find any info which could help me.

Yes

Which did you end up going with?

Me too! Did you end up upgrading?

How loud are they

Good choice, perfect balance between price, weight, performance

I think they are fine. More or less like the old Aeolus Pro 3. A more basic 3-pawl hub and a little heavier than the Aeolus Pro 37, but they should serve you well.

Great choice. I just bought de Emonda SL7, while doubting about de SL6 Pro :-). I would have fitted the SL6 with the 37's, because of the weight-penalty of the 35's and the 37's being brandnew design/R&D/based on the RSL's...when do you get yours? Mine is in in about 4 weeks :-)

@@anandjansen8002 I ended up getting the 37s on my SL6 for the reasons you have outlined. I picked mine up about 10 weeks ago!

...and I would add an other question if you don't mind: what do you think about mounting an xxx6 (or the new version of it if it will be available in the near future) only at the rear of an Emonda SRL7, to have a better aero performance without compromising crosswind stability keeping the Aeolus 37 at the front?

50 not good for windy conditions

Great set of wheels

48 Better.

50's are pretty stable unless you are going fast on decends and/or with crosswinds. If you combine those two you have to wear a daiper when going 50kph in a decend :-D I just bought de Emonda SL7 with these wheels, and had 62mm Reynolds Strike on my previous bike (BMC TMR01). Based on my experience, everything above 45mm is an aeroset, but not comfortable for allday use. The aero-gains from 37 to 50 are also marginal. Only if you cycle above 35kph all the time...if so: kudo's to you!

Ohhh thats a tough call.

Tough call. Same hub internals so that is quite nice. The Specialized use j-bend spokes that generally I prefer over the straight pull on the Bontys. That said, I know from experience that the Bontrager TLR system is about the best in the business so that would push me Bony especially for tubeless setups.

@@Jamesthebikeguy Hi James, I know it's has been 2y, but does Bontrager front wheel hub has option to convert to 15mm as C38 does?

This is for clinchers.

That would be a good upgrade

Aeolus Pro 3V, check my video here: kzfaq.info/get/bejne/Z9B4hal-qavYfX0.html

@@Jamesthebikeguy thanks 😊

The RSL uses DT240 so lighter internals but same function. Hard to say for sure but it is my opinion that the DT350 is more reliable than the Bontrager Rapiddrive hubs albeit not as much engagement

@@Jamesthebikeguy but do the DT Swiss' 350 sound as cool as the DT240 exp though

@@aces8481 of course not, but you can always upgrade the star ratchet to a 36 or 54 on the 350 hub. The 350 is known for being quiet.

faster engaging.

It's very quiet

Might be semantics here, but you are correct you cannot put a SRAM freehub body on a Bontrager wheel. You can however use/install a Bontrager XDR freehub body to use SRAM XDR Cassettes. (XDR Freehub body for this wheel is Part# W580844) SRAM doesn't make the freehub body, only the standard. Bontrager makes lots of freehub bodies for different standards.

@@Jamesthebikeguy Ohhhhhh, OK, great! That's the answer I was looking for. Now I know I'm not SOL if I wanna use my Rival 12-speed. Thank you!

The hubs, and the profile of the rim. So basically everything in terms of wheels other than the same diameter

@@Jamesthebikeguy in your honest opinion, do you think this one is better than the pro 5?

Not all hubs make loud clicking noises

If it's disc brake

Totally agree. DT internals, $1299... yeah that's sweet

Yes. I use 28 on mine, but I’ll be getting a smaller tire.

These are great wheels. How are you getting these /o decals. They are painted on, so are you sure you are getting real ones?

@@Jamesthebikeguy yeah. The hubs have the bontrager logo. He just didn't used it. Is it really painted or what

@@Jamesthebikeguy said straight from the factory, btw we are here in Taichung Taiwan where specialized and trek bikes or giant are made.

@@Jamesthebikeguy painted or Laminated ?

I broken my Bontrager XXX 6 Rear wheel and got a replacement from Trek’s dealer. They sent me a no decal rear rim for building my rear wheel in the dealer shop. I guess it is how a no decal wheel come from

$1299 ( $579.99 front, $719.99 rear )

I wonder if they are stiffer than my Zipp 303s I sold few years back ? I have the 404s now. Added weight to my Trek of course . These are nice 👍🏻

I'm guessing you didn't read the title.

@@Jamesthebikeguy Fair point. Guess I was expecting too much.
