They’re unlikely to be extra tight, you’d have a particularly hard ride and potentially many punctures, unless short spokes have been used and we go back to their QC dept. Again the wheel being true radially and axially doesn’t really mean that much if the spoke tension isn’t within tolerance. I’ll assume that when spokes have been added that attention has also been paid to other spokes across the wheel.

First port of call for me would be checking spoke tension.

It’d do no harm to strip it down and rebuild it, if Trek can’t sort it out under warranty, there’s nothing to lose.

I also share CreakingCrank’s scepticism of how much spoke tension contributes to the ride feel. I’d expect tight spokes to put extra force on the rim which can lead to rim failure (it goes from a circle to a (mathematical) saddle shape) but does it really affect how much the spokes stretch?

Also, how does spoke tension affect the numbers of punctures – I haven’t heard that theory.

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.

Interesting – I wouldn’t normally think that 2-cross vs 3-cross would make much difference to the spoke angles. Also, I would expect the nipple to deform slightly to accomodate that if they (more likely the nipple flanges) aren’t sitting flush with the rim. I’d say that 3-cross would be stronger than 2-cross, but mainly for resisting sideways forces on the wheel (including the forces when braking/pedalling).

A rebuild to 3-cross is a good idea though as it’ll force them to use a different set of spokes due to the longer length required.

I had a similar issue years

I had a similar issue years ago when I bought my first road bike – a Cannondale Synapse. However, I had rear wheel spoke breakages at the usual place where the spoke bends near the hub and it’s unusual to get spokes breaking near the nipple as that’s a stronger part of the spoke. The bike shop replaced the factory supplied rear wheel with one that they considered to be an upgrade to fix the issue, but that was even worse and noticeably went out of true after a short ride.

The shop kept trying to fix the wheel and it kept going wonky, so I got bored of leaving my bike with the shop to fix, so I tried to true the wheel myself and found that the rim was distorted and so the spokes had to be very uneven in tension to make the wheel round. Once I realised the rim was unusable, I built up my own wheel instead (the shop hadn’t agreed to me trying to true the wheel as they thought I’d been tinkering with it previously and had caused the problem).

With your problem, I wonder if maybe the spokes were under tensioned so that some of them were becoming unloaded during a revolution and that could explain the breaking near the nipple end.

I don’t ride in a club (I refuse to join any club that would have me as a member), but I’m sure they all vary a lot with their percentage of idiots. Those riders do sound like selfish idiots though.

I sympathise with your lack

I sympathise with your lack of faith in your abilities, but applying helicopter tape is pretty easy. As it’s clear, it’s not that noticeable if it’s put on wonky and most people just apply it on the locations where something (cables, frame bag straps etc.) can rub on the frame. It’s not usually used to wrap the entire frame as that does sound tricky.

I didn’t read this properly.  I thought you were talking about that article about dabbawalas – https://www.theguardian.com/global-development/poverty-matters/2014/jan/04/mumbai-dabbawallas-tradition-innovation-india

(Can’t remember where I read an article about this in the last day or so, and was sure it was in the Grauniad).

I remember reading about that – it’s an incredible feat of logistics. Also, I’d love to have a lunch-time tiffin delivery service, but not so keen on paying takeaway prices for it. (That’s made me hungry for a lentil dahl now)

I’m guessing that some of the scratches came from his very annoyed removal of a seemingly justified sticker.

He claims that the scratches came from the person placing the sticker such as if they had a belt buckle scratch the car as they leant across it. It makes sense as otherwise the scratches would be on the windscreen rather than the paintwork.

Thank-you for the interesting comments on this thread.

So  support for both “separated” and “protected” then, depending on context.

I’d agree with that and will not be using “segregated” to refer to cycle lanes in future. I hadn’t considered it previously, so thanks for raising this thread.

Driver’s fury as Volkswagon Lupo damaged by ‘rude’ parking stickers in Ramsgate

I guess a description of how he was parked wouldn’t fit the victim narrative. 

“[The stickers] were right in the middle of my windscreen so someone has leant over and touched the car to put them there. It’s a show car so deep scratches don’t look good. They definitely weren’t there before.”

I like his quote of “People just need to learn respect.”

Yeah mate, you need to learn some respect about dumping your private property like an arsehole. It got scratched? Good.
