  • thanks. But it states 95kfg an maximum? not sure what the minimum would be?

  • Anyone offering decent quality/price wheel re-building services? Couple of jobs awaiting:

    • Rear high flange vintage Record hub on MA2 rim - 36 holes
    • Rear + front high flange Sunshine hubs on clincher rims, currently sporting Fiamme sprints, could be 700 or better so 27 1 1/4 size - 36 holes

    Recommendations welcome

  • Got this hub surplus to requirements

    Brand new Bitex RAR13 24h rear, with alloy shimano spline freehub. Anyone want to take it for £35?

  • I'm planning to build a rear wheel with a Bitex 28h RAR8 hub and a H+Son SL42 rim, but I did a simulation and the spoke tension distribution would be 3% - 100%, which seems waaayy too uneven to me. What do you guys think about it ?

    Frame is alu so I can't respace the dropouts to fit a regular road hub.

  • according to the bitex link, should the centre-flange distances not be 28.05 and 16.45?
    why do you have a hub offset?

  • On the Bitex website, they show the geometry of the 130mm OLD version. I forgot to precise that I would use the 120mm OLD version, since my frame has 120mm dropouts. Here's the geometry of the 120mm version

    why do you have a hub offset?

    The hub offset is the distance between the center of the dropouts and the center of the hub, right ?

  • Yeah it looks much better with the offset removed - why would you want to move the hub so far to the left?

  • My bad, I misunderstood what the "hub offset" value was. I thought is what something related to the geometry of the hub, and I guess it's not.
    So the distribution would be 37%, 100%, is it doable/rideable ?

  • Assuming I'm understanding this right you'll have like 1/3 of the tension in the NDS. That's very bendy, one would expect no less than 2/3 in an average wheel. Get offset rims?

  • Here's the geometry of the 120mm version

    And this is why hubs got wider when we changed from 5 sprockets to 6.

    The NDS tension is going to be a third of the drive side assuming an equal number of spokes and no rim offset. If you insist on using such a wide cassette on such a narrow hub, you should at least consider an offset rim to bring the tension ratio to a more reasonable 2:1

  • Yes I an offset rim would be a must for this hub.
    The thing is that I don't necessarily need a 11s cassette for my bike, it's just that the RAR8 is about the only relatively new cassette hub I could find that has a 120mm OLD.
    Another option I'm considering is this kit which contains a 6s hub, but I don't know if it's worth the money.

  • At that price you could buy an entire 5 speed old school wheel and still have money left for a pair of plus twos.

  • Indeed, but I'd really want to build the wheel myself, so I can choose the rim and the spokes I want.
    And vintage 120mm wheels are mostly built with freewheel hubs, which is not ideal for me.

  • vintage 120mm wheels are mostly built with freewheel hubs

    With a couple of very unusual exceptions which are practically useless since they don't take HG cassettes, they all are. We went to 126mm before we went to ubiquitous freehubs.

  • Could you go for a sturmey archer IGH with 2 speed cassette (Brompton style)?

  • RAR8 is about the only relatively new cassette hub I could find that has a 120mm OLD.

    https://sunxcd.net/hubs is a 120mm (model SXL122) hub with a short freehub which takes various numbers of sprocket depending on spacing, typically 7 out of 10

    I don't think these hubs exist in 120mm OLD versions

    https://sunxcd.net/hubs is a 120mm (model SXL122) hub with a short freehub which takes various numbers of sprocket depending on spacing, typically 7 out of 10

    This is a beautiful hub and it would be perfect for me, but unfortunately it's out of stock everywhere I look.

  • Does anybody know if I can use DT Swiss end caps to convert a set of 2016/17 Roval SLX 24 disc wheels (DT Swiss internals, Roval AFD hubs) from 12mm thru axles to quick release? If so, which end caps would I need? Thanks

  • Those wheels are QR in the marketing pictures, so I'm sure Roval have replacement endcaps. They might be standard DT ones, but could very well be Roval specific. Have you tried asking your local Specialized dealer?

  • Is there anywhere you can buy Mavic Open Pro Clincher Rims in Silver (32h, rim brake) or is mavic open elite the only option?

  • Yes, the wheels come from new with the end caps for both QR and TA but i bought the wheels 2nd (actually i think 3rd) hand on here and didn't receive the other end caps with them.

    I've not had any luck with either Sigma or the Specialized concept store so might just order some DT swiss ones and see if they fit, but to be honest I got slightly lost when looking at all the options as to which ones I would need.
