Looking at the photos on the Trek website, the angle that some of the spokes are leaving the nipple is quite extreme. I think Trek have made a mistake using a 2-cross pattern on a 32-hole hub – especially an internal geared hub that has wide flanges. (edit: if it is a 2-cross pattern, in some photos it looks like it might be 3-cross!).
On lower spoke count wheels with a smaller flange hub, the spoke angle is less. See below a rough example, the green triangle is the same size, you can see how much greater the spoke angle is on the 32 spoke wheel of the District 4 compared to a 24 spoke Domane.
I’d ask them to rebuild the wheels (or at least the rear) in a 3-cross pattern.
Thanks, good point. I see what you mean about the angles. The only other bike I’ve broken spokes on was my cheap Chinese Bickerton folder, and due to the short spoke length it had some very extreme angles. They also always broke at the nipple.
Given you have the ability to build a wheel, have you (or even the shop) put it in a stand to check out the build quality/spoke tension? Even if just to eliminate that.I’ve never built one from scratch, but I’ve replaced spokes before and have access to a truing stand (I sometimes volunteer at the local bike Co-Op.) The spokes on this wheel have always seemed extra tight to me by feel, and they are really thin (I’ll measure them when I get it back this time.) At some point the tensiometer at the Co-Op walked off, unfortunately, but the mechanics at the Trek store are the most competent in town, so I imagine they’ve checked the obvious.
The wheel is very true both radially and axially when all the spokes are there.
I will add that I’ve never
I will add that I’ve never had a broken spoke, or even had to true, my Mason X Hunt 650B Adventure Dynamo Disc Wheelset. I ride it much harder and over chonky gravel, and have nearly 15,000 miles (24,000 km) on them. They do have a slight advantage with supple 48 mm tyres vs. fairly harsh Bontrager 40 mm, but they also only have 28 spokes per wheel, and since they use a cassette I’d imagine they have a steeper driveside angle than those on the Alfine 8.
Per Hunt:
- J-bend cold drawn.
- Made from high grade T302 (18/10) stainless steel wire by Sapim.
- Triple butted 2.0-1.6-2.0 (then 2.2 at the head for the patented Pillar Spoke Re-enforcement).
- 28 spokes laced 2-cross front and rear.
- Black stainless treatment.

This is very much my local area. I’ve ridden through this intersection a lot of times… it’s not the nicest area to ride, but there is a nice multi-use path that leads north out of town to the grid of quiet gravel and asphalt roads. I’ve chosen a photo that is American in every way. There are more photos in the article. The bed got ripped clean off the pickup truck.

Maybe there’s a petrosexual under there having sex with it. It will move off when they’re done.

I was tempted to buy one from my LBS, but wanted to hear it. Luckily they were okay with unboxing it and installing the battery to test it. It was loud, but sounded so unlike a car horn that I doubted any driver would know what to make of it. It went back on the shelf.

Somehow these people manage to tie their own shoes and use credit cards.
Obviously Paris is the City of Lights and all that but it might be taking it a bit far to expect pedestrians to be festooned with them. Is there anywhere in the world where pedestrians do habitually wear lights at night?I won’t walk on the rural roads here without lights at night. Many running clubs require them for night runs, and I even see dog walkers with lights on them and their dogs. But not in cities.
£1billion for ten miles of new roadNo mention of any active travel. Plenty of Save the Driver nonsense though.
Based on the numbers in the article, that’s at least £20 for every time a driver saves ten minutes of the next couple of decades. And I’m being very generous (lowballing the estimate.) It’s probably more like £100, so £600/hr.
Or, it costs close to £40,000 per road user. Would any of them pay that to save ten minutes off their work commute for the next 20 years?
