Well done!
What frame is this and how long is the stem on that cockpit? I'm looking for freakishly long stem options for a friend.

Thank you sir!

The cockpit is the Tavelo AROW. 140mm stem and 36cm width. I've used most of the usual suspects when it comes to one-piece handlebars. The Tavelo AROW is my fav in terms of having a good balance of price, weight, stiffness, and ergonomics. EXS is way overpriced.

First road race of the year. The 100km course has a few (wet & gnarly) gravel sectors, so I went with 32c GP5000 STR which stretches to 34mm at the rim. Carbon spokes is manageable on gravel but not ideal. Even with cushy tires.

Currently at my best fitness ever. NP 235w which is 3.2wkg for 3 hours and 15 minutes. Doesn't really matter though because my both bike handling and tactics are awful. Out of place early, and got dropped by the much stronger Cat 1/2 dudes about 45 minutes into the race. Ah well on to the next one...

Are you sure it's the carbon spokes, not the wide inner width that makes the tire walls straighter?

Any thoughts on this? I bought the D50CU to use with 32c GP5k on tarmac and light gravel.

 Two different thoughts bruh. It's the rim width making tires wider - and carbon spokes harsh on gravel even with 'cushy' tires. Peace out

OK. I thought the straighter sidewalls made the ride harsher, even if the tire got wider. Less lightbulb-effect.

So I got a quote for 65 mm T800 wheels with steel spokes and a 54T ratchet, priced at $754 shipped to the EU. The estimated weight is around 1550 g.

That felt a bit heavy to me, since my current 65 mm wheelset with steel spokes weighs about 1430 g — although it’s only 28 mm wide externally.

I then asked for the same specs but with carbon spokes. The weight would drop to 1400 g, but the price goes up to $945 shipped.

It’s a bit more expensive than I expected, so I’m still debating which option to go with.

Sounds about right for steel spokes.
How many spokes 20/20, 24/24 ot 28/28 and what hubs are being used?
Steel spokes are around 4grams a pop
And T800 rims around 495grams each

I have ordered 60/65 wheels from another suppliers T1000

Rim 60 450g +/-15g
Rim 65 465g +/-15g
H-Works hubs 20/20H 276g
5mm carbon spokes @2.8g each 112grams
Wheels 1303grams
Did ask and see if it was possible to hit sub 1300g but they cannot promise that but around that weight for a wheel of this depth is light.
