TrailWarrior Posted September 9, 2016 Posted September 9, 2016 May be a stupid question but here goes.... I currently ride with a 142x12mm rear axle and have spare wheels with same sizing. Buying a new bike, the axle size is 148x12mm. Does this mean I would now have to sell the spare wheels as there is no way of getting them to fit?

Buying a new bike, the axle size is 148x12mm. Does this mean I would now have to sell the spare wheels as there is no way of getting them to fit?Boost hubs are 6mm wider between the spoke flanges. The spacing of disc to frame on the left and cassette to frame on the right stays the same so that standard components like calipers and RDs will just bolt on. Converting your 142x12 wheelset depends if your hubs can accept alternative endcaps. LBS in PMB has successfully converted a few 142 hubs to 148 by making up endcaps that are 3mm longer each side. You also have to space the disc out by 3mm. I bought a new wheelset with my new frame but my old wheels with DT Swiss 350 hubs are apparently quite easy to convert and I may still do it. The cassette will retain its original chainline so you will need to use appropriate cranks. If your new bike comes with 1x cranks that have the wider 53mm chainline to suit boost hubs then you may have to put a spacer under the cassette and may even need a lockring with a longer thread....or you can put spacers under the chainring to move it in....or move the BB spacer to the non drive side if its a threaded BB in a 68/73 shell. There are many ways to get it done but it depends somewhat on what components you have. Do your homework to be sure it will be workable. Ideally you want to be able to simply slot the alternative wheelset in without having to bugger around with crank, BB and cassette spacers each time you change wheels. As an example, moving my old wheels and standard 2x10 XT crankset ( converted to 1x10 with chain ring spacers) from TBLT onto the new Hightower frame would be plug and play by simply removing the chainring spacers, converting the hub endcaps and spacing out the disc mounting. Another easy way to get a plug and play swap is to buy some boost hubs and get them fitted to your old rims. Sell your old hubs to offset the cost. Sent from my SM-G935F using Tapatalk
