Nope but the tire is brand new. The wheel has 32 massive spokes too so minimal lateral flex. Seems to me too that the pressure is way too high. Drop it and gain a tiny bit of clearance as well.
I redished the wheel and now it's quiet. We had a test ride in the parking lot doing some short sprints etc and it seems good. It looks so awesome and the owner is hungry for a ghetto mod so we're proceeding.
He had to buy an R8000 brake caliper, and we're going to grind down a tiny bit of material to give him ~2mm of clearance.
It's really cool to see a road brake caliper over a 35C tire. In the end we're going to have around 2mm clearance at the chainstays, brake bridge, and brake caliper. If all goes well...

Must be me... I would think dropping tension in the spokes would allow the wheel rim to expand and mean larger diameter. But I doubt that is a measurable, significant figure.
I believe almost nothing I read and 'hear'
I believe roughly half of what I see with my own eyes.. in person.
I do not carbon.. anything

I have to choose between 2 hubs for build Venn Var 501, DTswiss 240 EXP and Bitex 312 (These are in stock at my LBS for quick wheel build).
Without any read on this forum, I will go for 240EXP. But with the "240 EXP engagement problem" thread quoted few message before, I have some doubt to choose this. The Bitex 312 have simply maintenance, same bearings and simple free hub system. I search strong hub with long lifetime and the best hub geometry.
What would you do ?

Is it the BX312?
They have decent sized bearings, and flanges that aren't obviously inferior to the dtswiss.
What I have noticed with chinese hubs in general is that they're great for lighter riders that ride in good conditions.
When it gets really filthy or you put a 100kg rider on there, or a bull doing 1000w, then you might notice some shortcomings, (but this can be said for many hubs).
I ride chinese hubs for a long time. I don't have any problem servicing them. If you don't want to service the hubs then dtswiss is maybe more reliable in the long run.
Am I the only one that thinks that dtswiss straightpull hubs have quite poor geometry? Carbon-ti look better.

Yes, BX312.alcatraz wrote: ↑Thu Jul 29, 2021 11:37 pmIs it the BX312?

I'm 74kg for 180cm.
Carbon-ti is available at my LBS but they are too expensive for me.
Best hub are for my budget it's DT350 I think, but they aren't avaible everywhere... So I have to choose between these two, BX312 and DT240 EXP.
BX312 are chinese hubs, but top of range of chinese hubs na ?
I don't want to say "F**k I should have chosen the DT, these BX312 aren't reliable at all, I'm always on servicing them". Overall, I don't ride in storm and I have pair of alloy wheel with Hope RS4 for bad weather but, you never know !
Thank for your reply in any case
No, DT240 EXP isn't cheap, I'm agree ! But it's cheaper than Carbon-TI...
For this build (Venn 507, sapim CX-ray) here are the prices :
- Bitex BX 312 : 1180€
- DT240 EXP : 1390€
- Carbon-TI : 1550€
24 cx-ray spokes on realatively small diameter flanges of the dt240, does not sound like a performance wheel. It's fine for light riders perhaps. The hub might be endurance but the spokes aren't. So it's a slight mismatch.
What I mean, that's a lot of money and it's not going to compete with big brand wheels except with weight.
To maximize the potential of a spoke you need good geometry. To get a really solid performing wheel with standard hub geometries you either need a few more light spokes or some bigger spokes.
If you aren't going to ride in crap conditions then try Bitex and 24 5gr spokes perhaps. Save some dough.
If you want to splurge on luxury then carbon-ti cx-ray perhaps. Those hubs can make good use of the lighter spokes.
Or if you want an endurance wheel then dtswiss and 5gr spokes (not cx-ray)

You mean, CX-ray is not the "all-rounder" spokes ? I will must go with Sapim Race for example ? CX-sprint ?
I think I will choose Bitex hubs, quite good geometry, relatively light and save money. I have pair of alloy + Hope RS4 wheel for bad winter weather.
I'm 74kg with 360w @ FTP, mostly a puncher. I want something stiff and durable for my aero wheels.
