Number of spokes...

Morning all
Having taken advice from this forum and checked out a few options I have decided to purchase some new wheels made by a local wheel builder. They have miche hubs and kinlin rims pretty similar to the BORG31:

https://thecycleclinic.co.uk/collections/road-rim-brake-wheelsets/products/borg31-all-weather-aero-wheelset-24f-28r

My logic for buying them locally (for a similar sort of price) is that (1) supporting a local business (2) if there is a problem with them down the line I can take them back and (3) I don't have to pay postage :smile:

My question is around the number of spokes. I am 90kg and do a mix of recreational cycling plus some commuting. For the latter I carry my laptop, lunch and change of clothes. I ride down B roads which aren't great quality.

My question is whether the standard 24/28 set up would be sufficiently robust or whether going for more spokes 28 front / 21 rear would be a more sensible option. I *think* the Kinlin rims (XR31) are pretty strong but thought I'd check people's views re spokes before placing the order. The spokes to be used are sapim race double butted spokes.

Thanks in advance
Mark

    Sorry - I meant 28/32 rear

    I went for 32/32 when I was 90kgs. Better safe than sorry. How heavy is a spoke anyway? What I am fairly sure of is that you do not want 21 rear. Doubt anyone would suggest that.
    The above may be fact, or fiction, I may be serious, I may be jesting.
    I am not sure. You have no chance.

    Trust Malcolm advice. I would go 24/32, it’s only the rear that needs a bit more support

    Dear Fanboys, op's not actually using cycle clinic.

    There's someone else in the UK building wheels.

    Who knew.

    Obviously not a lot of potholes in your area.
    Avoiding potholes is preferable but sometimes shithappens.

  • Thanks all for your comments. I am tempted to go for 28 at the front and 32 at the rear. Appreciate the comments.

    There are no drawbacks in a having a few more spokes

    Seems like getting XR31 as a 32 spoke is pretty impossible. Have been recommended the DT Swiss RR511 instead for an extra £30. I am happier with the extra spokes but had my settled on Kinlin rims... Any thoughts?

    I have a pair of DT 511… I think they are better rims, in terms of quality, but. They are also marginally heavier

    My winter bike has 32 spokes front and rear, summer has super light climbing wheels with some minimal spoke count. I was very disappointed to discover via Strava segments that it makes very little difference timewise when climbing long hills (lets say 500V+ over half an hour it is like a minute and a half).

    IIRC in LA's book when he gets to recovery training he heads to the hills with his "lightweight wheels". They were 32 spoke. A different era but still...

    Marginal gains are all well and good if racing but I opt for wheel reliability.

    A minute and a half over half an hour is massive…

    2.5% is fairly insignificant if you are not racing. Also, winter bike v summer bike will have other differences. Horses for courses.

    To give you an idea… I improved my pb on a climb in Italy by 90 seconds… that’s a 20 minute climb… I needed about 30 watts more and 3 kg less, so 90 seconds is massive.

    I am responding in the context of the OP.
    Up to them to respond but I doubt they are paying that much attention to data.

    From a personal POV I can do the Mortirolo in 1:24 virtually on my trainer. I give zero F's if it takes me 2 hours in reality next month.

    Winter bike is around 9.5kg (steel is reel - and heavy after all). Summer bike is perhaps under 8kg. Winter wheels are around 2.1kg / pair, summer wheels are 1450g so with just the wheels the difference would be even less.

    For me, just pottering around, 2.5% is neither here nor there but with the winter bike I've done a lot of gravel paths as well which I would hesitate to tackle with the summer bike.

    I would expect it to be a lot less, a pair of wheels that save you 90 seconds on a climb, would fly off the shelves... the "magic wheels"

    650g extra on the wheelset, + the extra weight of the `winter bike`. If done in winter, + weight of extra clothing, mudguards and worse conditions. + `Winter` tyres too?

    Spa Cycles has Kinlin XR-31T and RT in 32H.

    I recently built a set (20F/24R with offset rear) for the Fred Whitton and I am very impressed by the general quality and glossy finish of the rims. I used CX-Ray spokes and the finished wheels are plenty stiff and work really well with wider tyres.

    The RR511s are nice too, but they don't have the offset option for the rear, and as previously noted, are a bit heavier, narrower and more expensive. However, you may prefer the look of DT Swiss decals to the plain black of the Kinlins.

    If I were your weight, I'd be tempted by 28F/32R on Miche Primato with CX-Rays or just go with black ACI Alpina DB spokes to save a fair bit of money over the CX-Rays.

    Here are mine with 30 mm Pirelli P Zero Race tyres.

    I'm pretty sure I recognise that bike from the FWC, I think we spent a lot of time swapping places.

    Couldn't have been me as I only built that up last week. At the FWC I used those wheels on my TCR, which is usually equipped with carbon wheels.
