I thought I’d go ahead and upgrade the drivetrain from a 1x10 to a 1x11 as a necessity for the extra heft. I had even gone to the trouble of ording longer cables for the job just in case.</p> <p><a href="https://www.chainreactioncycles.com/shimano-xt-m8000-11-speed-11-46t-cassette/rp-prod149701" rel="nofollow">https://www.chainreactioncycles.com/shimano-xt-m8000-11-speed-11-46t-cassette/rp-prod149701</a></p> <p>The current rear hub.</p> <p><a href="https://www.halowheels.com/shop/components/spin-doctor-rear-mtb-hub/" rel="nofollow">https://www.halowheels.com/shop/components/spin-doctor-rear-mtb-hub/</a></p> <p>Unfortunately when I was tightening the new cassette to the freehub the lockring split off. </p> <p>Long story short I read online of questions answered on the store page of the cassette I bought that said that the cassette would fit but it appears that in my haste to attach it I didn't check that the freehub body may have been too short after all, that and the larger gears are dished so that they rub the spokes preventing any backpedalling. This means I need to replace the hub.</p> <p>I’m such a fool for doing this sure but all research I did said otherwise, so I wanted to ask on what sort of hub I should I go for? Obviously an 11 speed hub, 135mm in width but I wondered if an internal gear setup would be better. After all, the solid axles may be better suited for carrying loads.</p> <p>I was thinking of the Alfine by Shimano but I’m not away of anyone using it for a cargo bike and I’m not keen on spending so much on the rohloff 14 speed internal hub as it is. Nuvinci I’ve heard have some reliability issues.</p> <p>I'm not going to install a front derailleur as my whole setup revolves around a simple drivetrain (as awkward as that may seem). </p>
