The post that was referenced speaks of dati hubs being of poor quality; so why would you pick the dati hubs over the circus monkey ones based on that topic?

Oh? Maybe I misread I thought it was referring to circus monkey.

has anybody worked with the xr-270? I'm seeing two ERD's from numerous places. I'm seeing 587mm and 585mm anybody know which one to go with? and as for the hubs these are the dimensions I'm seeing.

If I'm putting in the calculations correct the spoke length should be 278.2(587 ERD) or 277.2 (585 ERD) for radial lacing the front or 286.5(587 ERD) or 285.5(585 ERD) for 2x lacing.

Would it be better to round up for spoke lengths or round down?

When you get the rims measure yopurself and when you get the hubs measure yourself. It is the only way to be sure.

The ERD is 587mm bty but really measure yourself as it is an effective rim diamter and depending on how you measure 585mm could be right also. There is always an acceptable range.

277mm or 278mm should both work if for radial spoking based on those measurements. The 277 will mean that you will come up to tension alot quicker. and you might have part of thread showing on one or so spokes. IO would plump for 278mm.

But really measure yourself. doing the ERD your self also helps decide if the rim you have is round to start with.

for now i have builded 3 set of xr-270, i always take 587 for ERD take on bikehubstore website, everything was always good with spoke length, and i'm already building an other set with xr-270

for the weight, i have build a 24/28 kinlin xr-270, sapim laser front, laser nds, race DS, alu nipples front and NDS, Brass DS. With BHS hub for 282gr for the set and it came out at 1503 gr including rim tape(38gr) so you can get it to around 1475 gr with veloplug. Circus monkey seem comprable in weight with BHS hub.


The build i'm doing now, is 20/24 xr-270, laser front R NDS, alu nipples, Rear DS race and brass nipples, with a set of 260gr hub, with veloplug and i'm just under 1400gr, around 1390gr.

We use the stated ERD of 587 for all of our Xr270 builds, and that seems to give us just the right length spokes.

thanks for all the help guys I'll probably begin purchasing components soon

The combination of BHS rear hub with its suboptimal geometry and low max rim tension is not going to yield a durable wheel with lower spoke count. The extra low NDS tension will cause problems on that side, especially for 180+ lb rider. Contrast that to the use of Kinlins XR-270 or 300 with good high tension on DS, and the BHS hubs will do well.

Thought I'd pop in for a reality check. I'm wondering about spokes. Thinking about getting some Nemesis 32s with CK R45s built (with Veloflex Roubaix). How does Laser or Revolution with Race or Competition on the DS sound? I'm 88 kg and am not after a 'bombproof' set. Just something that will ride nice and stay true (and be reasonably non-heavy). I'm not hard on my equipment and the roads around these parts aren't too bad.

Sounds fine to me. I have built several wheelsets with that sort of spoking for 90-95 kg riders although on OP's or RR465's and there have been no issues with the wheels.

TuplaO, sounds great. My typical build from 24h to 32h is Laser NDS and either Race or WS DB-14 DS. Only for heavier guys, softer rims, or tougher conditions do I veer off this for road or cross. That's notwithstanding using CX-Ray all round if budget allows.

^&^^Thank you, gentlemen. To be honest, I thought as much. It's just that so many around the internets are 'going foolproof' that I started to doubt myself...

would just like some opinion's on my next wheel build.

i am planning on using tune hubs mig70/mag170, BHS472w rims, cx ray spokes.

they will be used fairly often, but i want something thats race worthy for when i don't feel like running my tub's.

im 80kg (google says 175lb). not hard on equipment but a fairly aggressive racer.

i was thinking 20H radial front, and 24H radial DS (heads in?) and 2x NDS.

is the tune hub suitable for that patern? i am leaning towards the lower spoke count for the weight and also aero advantage.

I would lace the rear 2x both sides. Why do you want to do DS head in lacing anyway? Radial DS spokes are used to redue the ammount of peak loading the rim experiences. This allows a lighter rim to be used. The rims you have picked is not that light anyway so I am not to sure what you are going to gain. It makes some sort of sense for some wheel manufacturers to do as they can design the hubs, spokes and rim to work together and only makes some sort of sence to shave every last gram of the rim but more weight will be needed at the hub so it's a trade off. You would also need a large NDS flange to help with torque transfer. The tune hub NDS flange is not very large at all. It small to keep the weight down. Heads in DS radial spokes are going to put a fair bit of load on the hub flange I really don't know if the tune hubs are up to it but I would not take the risk with such an expensive hub.

In fact when doing a handbuilt wheel you should be doing the same i.e. seleting compents and lacing pattern that ompliemnt eah other. I cannot see any signifiant advantages for the pattern you propose only downside.

So in my opinion don't risk it but maybe someone will come along who has done it and found no problems after a few thousand miles.

If you want heads in on the DS, do 1x. But you only need that if the hub has a narrow DS flange spacing and if you need a laterally stiff wheel due to your riding style. If the flange spacing is greater then you run the danger of the spokes interfering with the derailleur cage (bladed spokes may address that somewhat depending on where they go from round to bladed section and the flange diameter).
