Dec 12, 2021 at 9:47 comment added Chris H Interestingly @MaplePanda while there are tickboxes for the true length, they haven't actually been ticked
Dec 10, 2021 at 22:55 comment added MaplePanda @ChrisH Looks to vary heavily by brand I guess. The Shimano ones I'm familiar with have packaging like the following with many length options: ebay.com/p/14006749252
Dec 10, 2021 at 9:56 comment added Chris H @MaplePanda With QR on my steel and aluminium bikes I can see that. However they seem to be titled by nominal size ("front"/"rear"/"boost") rather than actual length, with the actual length in the specs if you're lucky. This all reminds me - I need a new skewer for my hardtail: external cam+ disc brakes mean I need to check frequently or risk losing the wheel landing even my little jumps
Dec 10, 2021 at 2:37 comment added MaplePanda @ChrisH See my comment to Weiwen. Side note: there’s the 141mm “QR Boost” standard used by some budget hardtails, and there might be fat bike stuff too.
Dec 10, 2021 at 2:36 comment added MaplePanda @WeiwenNg It’s been a while since I last bought a QR skewer, but I remember they were sold according to external dropout spacing. Aluminum frames with thicker dropouts would need longer QRs than thin steel dropouts. I suppose it varies greatly.
Dec 9, 2021 at 22:40 comment added Weiwen Ng @ChrisH Salsa lists fat bike QR skewers on their website, and they were really wide. That’s the exception, though.
Dec 9, 2021 at 21:52 comment added Chris H Note (@MaplePanda) that the nominal dimension of a mechanical part may not be any physical dimension on the part but a mating dimension or a reference dimension. This is particularly true on threads for pipes, but even common metric screws are always narrower than the nominal size (the thread is specified to be flat-topped; if it wasn't, the diameter would match the nominal size)
Dec 9, 2021 at 21:52 comment added Chris H I reckon QR from the pic of the 2020 model as well. I'd be surprised if a >135mm rear hub was QR, so 135mm should be good. I read just enough German to reckon the specs don't give that much detail even if I look at "Nabe (hinten)" (rear hub) on the 2020 model and search the part number, it seems to be a discontinued OEM part, and the new model has both QR and TA versions.
Dec 9, 2021 at 16:33 comment added Weiwen Ng @MaplePanda true. For simplicity, I omitted that part. The fact is almost all retailers will list skewers as 135mm, if they list a length. Interestingly enough, Trek seems to list its skewers in actual length. trekbikes.com/us/en_US/equipment/cycling-components/bike-wheels/…
Dec 9, 2021 at 16:03 comment added MaplePanda A hub with 135mm over-locknut distance evidently needs longer than a 135mm skewer.
Dec 9, 2021 at 15:24 comment added Weiwen Ng @AnuBhuvanendranNair I don’t read German, but I think I see quick release nuts on the drive side of the bike. Thru axles would be flush with the dropout.

Dec 9, 2021 at 12:13 comment added Anu Bhuvanendran Nair Thank you very much @Weiwen. I updated the question with the link to the bike model. From the index entry, I think mine is not thru-axle.
