When you could learn everything in 5 mins with a google search but post a question on a forum cause you couldn't be bothered, I don't really feel much simpathy

Why no?
Because there is nothing to back it up with?
lol
Gotta love the marketing machine that is Specialized they are the best at what they do.
New SL9 is due this year probably 15watt faster stiffer more aero etc etc so I'm getting one

Info is proprietary but its significant for front wheels, rear wheels could use more spokes for pedaling stiffness. Don't have any data to give so I wont die on this hill.

That's a pretty bold statement, could you elaborate bit more?

no

I have a stupid question that is with same wheels and tires or gravel setup?

gravel setup iirc

Hi all,

We're considering to develop a new 50mm carbon road rim and would really value some feedback from forum members

Concept Direction:
   •   50mm depth
   •   Modern U-shaped aero profile
   •   25mm internal
   •   ~32mm bead / ~34mm max external
   •   20 front / 20 rear
   •   Lightweight performance-focused rim


Rather than chasing extreme gravel-style numbers, we're trying to optimise:
   •   Efficient U-shaped aero profile
   •   Lower overall rim weight
   •   Improved system load tolerance
   •   Better impact resistance than typical ultra-light race rims
   •   Compatibility with 28–32mm tyres (optimised around 30mm)

Spoke holes would likely be drilled with internal reinforcement for flexibility across hub types.

⸻

Open Questions:
   1.   Is 25mm internal still the right direction for 2026 road use?
   2.   Is ~34mm max width ideal for modern 30mm tyre setups?
   3.   Would you prioritise lower weight or higher load/impact margin?
   4.   20/20 rear — acceptable for modern road builds?
   5.   Any concerns with U-shape profiles at this width and depth?

Looking for constructive technical feedback rather than brand comparisons.

Appreciate any thoughts.

need 18 spokes front for aero, specialized does it on the newest rapide and its significantly faster than higher spoke counts.

its worth noting that my cda is .210 in an optimized position on a 2026 s-works sl8 with all the nicest kit, Seka claims that their aero gravel bike vs their road bike is .012m^2. The seka road bike is very close to the sl8 in aerodynamics so one can conclude that a aero optimized gravel bike can come pretty close, if you assume the seka spear is just as fast as the sl8 and account for the drag difference between spear and exaero you can give the exaero gravel bike a tour aero rating 223w

this aero nonsense is a joke.

You have to be about 20mph to see gains in aero on gravel. when mvdp won the gravel worlds i was 22mph in that race. 

so it is pretty safe to say none of us aero will matter one bit ever.

so back to your bickering

at a cda of .35 (mediocre for a optimized tallish gravel cyclist) here's speed (mph) and watts required to overcome drag.
15=65w
16=78
17=94
18=112
19=131
20=153
21=177
22=204
23=233
24=264
25=299
26=336
27=376
due to the cubic nature of aero drag and that so many key sections in gravel racing occur on the flats where speeds can exceed 26mph easily aerodynamics obviously matter.

does anyone have pictures of how these fit?

If you need to produce something, I highly recommend https://www.tarstone.com/, Lena helped me produce jerseys for a local team, they were amazing, super fast, helpful, and had excellent prices, I used one of their suits for 100+km and the pad had no problems.

curious how these fit, send pics

Hey everyone!

My name's Anatoly. I just wanted to share my build based on a Epic WC frame - nothing fancy, but it's coming together nicely.

All the components are visible in the photos. Total weight with pedals and bottle cages is 20.3 lbs. The stock shock fits like it was made for it - no issues at all.

So far I've put in 100+ miles, mostly local rides. Really looking forward to hitting real MTB trails once the weather warms up!

Thanks for taking a look - and if you have any questions, I'd be happy to answer them!

holy chromatic abberation, invest in some nice glass

Hi all,
long time lurker and here comes my first post

I'm interested in the CSC FS278 rim brake carbon wheels from CSC.
The T800 rims with 3K brake surface look very good to me, and so do the 1423 spokes.

They're using "their" FS278 hub with 4 pawls. I'm wondering who the manufacturer of these hubs is, for future maintenance and parts.

Anyone?






thanks

looks like "chosen" to me

I got this jersey here.
With a undershirt and a gilet been good for about -5C
It's got long arms and tight hems.
Long enough for me and quite snug which I like.

The color is a bit muted.
I'm 193cm and 78kg with a 102 cm chest. Went with a European L as per size chart. Could've been an XL for looser fit.

What bibs? more people gotta post pics of how the kit fits.

Hello, just finished building my bike. I need to make some adjustments and will be getting a replacement front wheel, as the one I got had a flexible spot.

rotors and font lowkey ruin the build, super ricey and cheap looking

Me hab escrito hoy diciendo que en mi talla M, si quiero el cuadro estándar, tendría que esperar hasta marzo. Que si que tienen otro que es más ligero. Me ha mandado un vídeo en el que se ve como flexa el tubo cerca del pedalier, al presionar con los dedos, pero que esto es así, en versión ligera. Conocíais este modelo más ligero?

Can we have more details on the lightweight version?

Quote from: toxin on November 10, 2025, 11:06:16 AM
Hand drawn rendition of some changes I'd make. Mostly focused on dropping weight by giving the rear some Incolor SSR and Scott Foil treatment.

This is nice, dont like the transition from headtube to top tube, I think the slow taper looks really ugly and dated.
