- Boost question
Depending on how old school steel your singlespeed is, you could spread the rear apart (oo err missus) to become 148. I have sprung a 120mm road frame apart to 130 in order to fit modern gears, 135 – 148 is only a few mm more. But once I did it, I had to bend the dropouts a bit to get them parallel again, otherwise the rear wheel wouldn’t bolt in straight. A bit of a faff tbh. Then you could fit one of them skewer boost hubs scotroutes mentioned (which I hadn’t heard of before).
Depending on the dimensions, it is possible that hub adapters designed for QRing standard width hubs would have the correct spacing for boost width? And anyhow, if you are bending your frame to fit, a mm or so won’t matter.
Why do you want to do this?Posted 10 months agogreyspokeMember
I would tentatively say that boost for 10mm QR would be made with an “over lock nut” of 148-7=141, much in the same way as standard width 142×12 is 135+7. The extra 7 being for the recesses in the dropout so it is easier to slot the wheel into the frame accurately before fitting the axle (compared to 135×12 where it floated about until you lined it up well enough to stuff the axle through). As QR axle ends fit into the dropout anyway you don’t need the extra 3.5mm each side.
So actually my post above is wrong, you would only have to spread your rear end by 6mm, which would not be much at all.Posted 10 months ago
