I would use the Kinlin XC-279 for you Eric 20F/28R it really is much stiffer than the XR-270 and spoke breakages will become less frequent. The Hplus Archetype is another good rim but not as stiff as the XC-279 but stiffer than the XR-270.

I suspect a stiffer rim will do more to help spoke life than an offset rim.

I was not in any danger. The worst thing that could have happened would have been the wheel going out of true suddenly on a descent, which would probably not locked the wheel just put on the brakes. When the flange let go it was just like breaking a spoke, and that's no problem. I'm used to it.

I've been using the SL211s since BHS started (3 years ago?) and have been beating them up pretty hard. I think I have had one bearing get a little rough, and it was not difficult to replace. The freehub bodies seem to be very durable for aluminium freehubs. They get gouged much less than other alu freehubs I have used. The SL210 has one slightly larger bearing (two 6903 and two 6803 vs one 6903 and three 6803) and slightly better DS flange spacing. I'm going to use that on the wheel to replace this one.

On a couple SL211s I have had the axle end caps come unscrewed. It causes a squeak and sometimes a slight amount of play at wheel. I've used loctite (#242) to keep them in place.



So, you change one bearing and you never change the freehub body after 8000-10000 miles on it. That's over what i was expeting from these hub. Thanks for the info.

Hi guys perhaps you can help me sort the wheat from the chaff.

I just posted this on the road bike review forum but thought I would try and double my options!

I am in the process of ordering two sets of wheels as per this thread:

Tokyo Wheel - Epic 60 - Carbon Clincher Wheelset - Recent Purchase

Whether they end up being Tokyowheels or not, I am going to order a tubular wheelset built around DT240 hubs for training as I can get these hubs serviced easily. I want to build an almost identical wheelset (for easy swapping out) but with lighter hubs.

The build would be based around a 38mm front and 50mm rear rim with cx ray spokes.

My frame is being painted Lamborghini pearl orange so I originally thought orange hubs - two obvious choices Chris King R45's and Tune Mig 70-Mag 170's. I eventually decided on Tune Mig-Mag's as they are lighter, I won't have to spend $180 on a proprietary tool to service them as with the CK hubs. I live in an area that does not have a really knowledgeable technician so final hub choice would have to be fairly easy to maintain and service. It seems Tune now have problems with supplying the rear hubs and the issues may take 6 months to resolve. Nobody seems to have the orange hubs in stock at the moment. The CK hubs don't provide much in the way of weight savings over the DT 240's either and I have heard some mention of increased drag due to the design.

Anyway, my wheel builder mentioned that orange hubs might look wrong if they do not exactly match the frame colour and has recommended black. Again, his distributor doesn't have the Tune pairing in black in stock either (Fairwheel) so I am stumped. What other light, reliable easy to maintain and service alternatives are there out there. (I can't do Carbon TI as they don't do Campagnolo and they are re-designing a new model to be released in 6 months. Alchemy also don't have Campagnolo.)

I am considering an Extralite SL2 and SLX pairing but wonder at the longevity of these. Pehaps you guys can help.

The wheels will be used for about 6 months a year for weekend warrior burn outs and the odd race so they will average about 6,000km a year. I weigh 65 to 70kg.

So to sum it up. I am looking for the following:
A hub in the Tune Mig 70 Mag 170 weight range
Just about bomb proof
Easy to service and maintain without specialist tools
If it looks nice even better.

Or do I just suck up the extra weight and go the Chis King route.

Any suggestions would be welcome!

You know the tokoyowheels are farsports, right? But at about double the price.

FarSports "edhubs" are 190g rear 66g front. Made by Bitex. The're good quality and weight for the price especially if you get them through FarSports rather than paying much more for them from Tokoyo.

You can also get different, lighter (but not as wide) rims.

Whit Industries T11 are easy to service but a little heavier at 345g/pair. Still not too heavy by any standard. I would not bother though and just use Miche, cheap easy to service (a bit heavier at 440g/pair) but as they come in 20F/24R drillings and cheap and very reliable what not to like.

Bitex hubs are not bad I think and there is Novatec A291/F582 SB-SL at 290g/pair.

Have a 32h silver Record front and wondering about lacing to a 24h carbon rim using a crow's foot pattern. It would have four groups of three spokes per side, with four spoke holes empty. I'm a bit nervous about both the empty hole and the radial spoke in each of the groups of three.

Anyone have any experience doing this, or recommendations pro/con with your thinking?

Thanks!

Well given it a front wheel it has a greater chance of being a stable wheel. It is still a comprimse though and you will need more than one spoke lenght just on one side. How you go about calculating those lengths I do not know but a drawing will be required.

Legit question.

I have plenty of 32 spoke wheels, have a Campy 32h set in hand, love the way Campy hubs roll, and want a 24 spoke front tubular. Also like the look of crow's foot lacing; probably wouldn't do it on a regular built, but was thinking it might a good way to make use of the hub.

I suppose an option is to sell the 32h silver Record pair and buy like a silver WI drilled in 24.... but I'm reluctant to let the Record pair go.

silver record hubs sell for good money I would do that and buy the WI T11's. If I did not have a set of 28H record hubs and 32H chorus hubs waitng to be built up I would make you an offer.

Hi all,

I rarely comment here, but Eric's post (Eric's one of my first customers - hi Eric, glad you're okay!) warranted a quick reply. We do not recommend - and will not warranty - hubs laced 1x on the DS. After Eric's initial success with this lacing pattern, I recommended it to one or two customers. But over the past three years we've seen just three rear flange failures (and only one front flange failure). Every one was laced 1x on the DS. Just don't do it!

That said, 8000+ miles on a hub laced like this - and probably not ridden softly (sorry, Eric!) - that's not too shabby!

That is all.

Brandon

I've posted before about building wheels 1x heads in on the DS to increase bracing angle. I think I am done with that experiment:

This happened today during a double century, causing a DNF. There's 6 more cracks around the flange. I used this wheel last year and this year as the training set for my main bike. It probably had roughly 8000-10000 miles on it. I'm going back to 3x DS and 2x NDS (3x since these are 28h).
I'd rather break an NDS spoke periodically as its possible to ride with that (with some field truing, for which I carry a tiny emergency spoke wrench).

Hub is a BHS SL211.

I have some 12H slotted DA 7700 hubs which I want to lace to 88mm deep rims. However which spokes. I would prefer to use a 2.3mm spoke at the elbow. which ones. Given the spokes will be very short would there really be a measurable disadvantage to using round sapim strongs compared to a DT Aerolite or sapim CX-ray which are not sold in the U.K and I will have to find on-line somewhere.

I suspect there will be no significant disadvantage to using the strong spoke I think they just fit anyone got opinions on this and weather a 2.3mm spoke and DA hubs should ever mix.

I am finally building the ArchTek rims I bought years ago from the group buy on WW. I measured the ERD as it is outlined in this popular spoke calculator http://www.wheelpro.co.uk/spokecalc/

The rims are 20 mm carbon tubular rims 20/24 hole rims

The ERD I got is 610mm the problem is that the spokes I bought for a 2 cross spoke lacing are too long.
The measurements for the front dati hub are 31mm for the flange diameter and 33mm for the distance
in between the flanges. The spoke calculator returns 300.9mm for the length in a 2x lacing.

Has anyone else measured the ERD on these rims?

If it is close, you could add sapim polyax wahers (each is ~0.7mm thick, or add 1.5mm to ERD for calculations),

Yes I have the washers but the spokes are still too long.
