Quote from: jonathanf2 on October 16, 2026, 11:33:55 AMI was shopping around last month for some low weight carbon wheels. I was considering sub-1kg wheelsets, but the cost difference seemed a bit ridiculous for a few extra grams. I found these Go4sporting wheels and thought they hit the cost-to-weight ratio decently. 50mm depth, 30mm wide, 23.9mm internal width wheels with 5.2mm carbon spokes. It took a month to ship and I weighed everything to 1140g total. Everything appeared true and well made. I already have some narrow depth climbing wheels, but I wanted something with more depth for those flatter sections.

Added photos fully mounted on my SPCycle R088.

i'm running the same wheels but laced with a bronze hub, all the other features and weight is identical. More than 1000km on them and the weight saving (coming from 1400g wheels) is noticeable
Mine comes with CSC strip sticker on the rim
Bought this summer for 380€ (shipped and no duties Italy)

can somebody rate the difference between ultegra 12speed calipers and Zrace?

Regarding bottle cages, I have these ones, that were suspiciously cheap, but they are amazing, especially for such low price.

6 months with them, never loose a bottle.
Re thighteed 2 time the lower screw that tend to loose

any news on build up of this frameset?
Is the BB confirmed "T47 86"?

the diameter of the cable gives you the difference between good and bad cable

I always use "bad " cable for small applications

new brake pad are not parallel each other.
Brand new rotor are always with some micro "chip" in the machining
I always suffer a little when using new brake pads so I try to aling as better as I can than...the downhill let the brake pads bed by themself


That's why professional teams and advanced shop use this bedding machine

dear, I'm looking for an used SL7
What is the weight for a 54size replica SL7?

it seems the problem is the in the cassette body bearing, not in the hub body
Probably it's the external bearing

what is the perfect balance between weight/cost/function in the 11 speed di2 groupset (105/Ultegra/DA)?

It seems that the Ultegra shifter are identical to DA (button/reach) and you can save 20g with titanium aftermarket brackets.
The from mech seems to be DA/ultegra identical
The rear mech are internally identical DA/Ultegra (motor/gear) but the 50g difference?

they're std Dtswiss but new model with inner groove and not the old model without.
I swap 3 different ratchet from different wheelset/source without any problem.

The spring are not all equal, some springs are not compatible with grooved spacer (it's a matter f 0,1mmm)
There are 4 different set of springs:
conical springs (old model)
cilindrical springs (with round wire)
cilindrical springs (with flat wire)
cilindrical springs (with flat wire "double loop")
+additional trick: spring on one side, teflon ring on the other one

Is the difference from 54 to 60 noticeable? Yes.

The crisper the sound (in garage) the higher the headace in long alpine descent...

if you match correctly you can manage the balance between drag/sound...

it's not an issue, it's a clear reccomandation given by the producer.
That's why I never swap to TPU with rim brakes but I kept tubeless

What's a good USD price for the 280g version? Cheers

the effective weight of 167.5mm version with all the hardware is 308g.
The 280g is only the 2 arms with shaft, so the 280g weight is "fake".
I payed mine +- 320€ with all the unexpected duties included (36€)

Flawlessly paired with coospo S10

I think so, but you have to try expecially for the axle lenght and endcap

I own exactly the same wheels 40x30 (they're effective 42mm) CSC and I used +- 3500km so far without any trouble,
The only issue was connected to heavy drag of ratchet that I reduce with different springs and different setup of ratchet and a lot of grease.
I'm selling this wheelset because I improved my ride with the carbon spoke version 45mm tall with 23,5mm inner width.

I think that the warranty is very difficount to get, the responsability is connected with pothole (in Italy we have very bad road condition) and...bad luck.

that's very common due discontinuity in production and poor quality control procedures
