FARSPORTS DISC CARBON WHEELSET Test & Review

[Theopiot]

thanks for the advise, just ordered a pair of 50mm 24/30 UD matte. cant wait to try them and see the difference between my pair of zipp 303

[ullmanz]

I want something aero and that climbs well hence the 45mm. I live close to the mountains and currently ride zipp 303 firecrest. What are the main differences between 24/30mm and 21/28mm wheel with a 28mm tire?
Thanks

the main difference will be how wide the tires blow up.
e.g. a 28mm GP5000 on a 21 internal width is around 30mm, a 25mm blows up to about 28mm.

so now you need to decide what is the final width that you want to run.
A 21/28 will allow you to run basically anything that you can run on a 24/30, but if the tire gets wider than the outer width, you lose on aerodynamics.
On the other hand a 24/30 will "force" you to run a minimum of 28mm tire, because of safety concerns. Although some people run 25mm tires on 24mm inner rim width.

Furthermore, the wider the tire, the heavier. So you will also add not only additional weight for the 24/30 over the 21/28 (although that is marginal).
The weight difference between a 25 and a 28 is more significant

I live in the mountains of Colorado and climb on hills with the Farsports Hypers 50mm 24/30 with the carbon spokes (weight 1210 grams). The tires are 28mm Contis GP 5000 TRs. The Bicycle Rolling Resistance website found the weight difference difference between Contis 25mm and 28mm tires was 10 grams per tire. The ride comfort and handling on the Tarmac SL8 with the 28mms is noticeably better than the 25s. I will never go back to 25s. And I don't think the aerodynamics suffer with the Conti 28s on the 24/30. The tires are ever so slightly wider than rim. To the naked eye they look flush with the rim. The wheels climb well but it helps that my bike that weighs 6.6 KG. Biggest downside is when the wind is gusting over 20 mph with a wider rim.

Interesting that they measured 10g per tire. I actually had weighed mine and it was 50g. But could have been a measurement error.
According to https://www.bicyclerollingresistance.co ... 00-s-tr-28 it's 30g per tire. Maybe i remembered it incorrectly and it was 50g for 2.
Anyway, my point is, think of what measured tire width you want to run (not the claimed width), and then choose the rim accordingly

Just got my 50 deep 30 wide 24 internal glossy UD wheels, carbon spokes on RD270’s

Look perfect upon inspection. 1246.1 grams inc. tubeless tape.

There was a post on this thread on 1.24.24 showing the width of the 28mm Contis GP 5000 tr on the Farsports Hypers 24/30, hooked rim (see pic). It was 30.63 mm wide. Regarding tire weight, Rolling Resistance measures "specified" and "measured" weights of tires. I think "specified" is what is advertised by the manufacturer. On that link, the measured weight difference between the 25 and 28 was 10 grams for the tires they tested. Turns out the 25s weigh more than advertised and the 28s less.

Just another data point, average width for my 28mm GP5000 TR on my 24/30 FS hooked rims is around 31mm at 63-65 psi. Of course, as with any tire there is variation and I can get over a half mm difference depending on where I measure the tire so it's easy to attach excessive precision to the measurement. And the width will also vary depending on pressure used. Also, it takes a few days at pressure for the tire to stabilize to its final width. Mine measured about 30.5 when first installed and settled out a half mm wider.

Can I just check if anyone was aware that the Farsports RD230 hub was not compatible with Shimano 12 speed? I put a 12 speed cassette on my RD230 as I presumed it was compatible but it started creaking after a couple of climbing trips. Emma informed me that it is not compatible with Shimano 12 speed (Edco monoblock). Other than the creak, it wasn't problematic. Has anyone else done this? I am now looking at a new RD261 hub to transplant into the current or getting new Hypers. Farsports were good and did send me a replacement hub (another RD230! I think) but I said I would put something on here to alert others.

Just remove the small ring at the back of the cassette and you're good to go:

Does anyone perhaps have Hyper wheels with carbon spokes with 24 spokes? But still with Farsport hub?
Probably not RD270 as it has 20 spoke holes, but their heavier RD360 has 24 spoke holes. It is much heavier hub, but it is in the center of mass, so does not matter so much.

Would I see much greater acceleration from 24 carbon spokes, than from a 20 carbon spokes? Low inercia and fast acceleration means everything to me.

Already have one wheels with their RD360 hub with 24 carbon spokes. Wave series. Specially made. But it is a gravel wheelset. Riding them on road, but had no problems, and they are super responsive. And was wondering if 24 carbon spokes instead of 20 spokes have an impact on this.

No

to me the wheel feels super stiff already with 20 spokes. I don't think there would be much difference with 24. You're just adding weight and possibly drag

[Agent041]

Thanks for the info. Will probably then go ordinary 20 spokes with RD270. 40mm deep, 24int./30ext.

Interestingly I already asked Farsport about that option with 24 carbon spokes on their RD360. They could do it without problems, even when 40mm, 24/30 is not in their program with other foreign hubs (that already are for 24 spokes). They would make 24 holes instead of 20, and do the specefied setup.

Hi

Can't make up my mind between the RD270 or Extralite hub. This is a dream build so I am not too concerned about the extra money, but is there any reason (aside from £££) not to go for the Extralite hubs?

On the shallowest rims with carbon spokes we are looking at a weight saving of 94g if I go with the Extralite over the RD270. But the Extralite is 6-bolt so there are additional weight savings to be had there when you factor in rotors.

Overall it's looking like about 130g lighter for the Extralite hubs on the FSD30 rims vs RD270 hubs on the FSD35 rims.

Will probably go for the Extralites but just wondered if I am missing a trick or likely to face issues with practicality.

Thanks

The spokes for the extralites are different and much more failure prone. Check out the failure that just happened in the Light Bicycle thread. The spokes used in the RD270 hub are different and do not have bonded in inserts like the ones that are used in normal hubs.

Of course. They build you whichever configuration you want. Almost everything is possible. I let me build several completely custom wheelsets from them in the past.

They would do it. They confirmed it. But upon some opinions that stiffness should not be affected, and responsivness should be the same, I opted for classic RD270 with 20 carbon spokes.
