Mavic Tech Forum
If you have any technical queries about Mavic products, please post them here
We used to run the bikingbarn website (for those of you that have not come us in the past – we were the primary stockist of Mavic spare parts in the UK) and during those six years we built a strong reputation for product knowledge and customer service.
Whilst we no longer sell the parts, we recognise that there is still a demand for advice, so we hope these forums will facilitate that.
What adaptor do I need to convert my Crossmax from 100mm to Boost 110mm

I have a 2019 Crossmax Pro 27.5 front wheel with a standard 100mm hub, which adaptors do I need to convert it to a Boost 110mm setup ?

Unfortunately it is not possible to convert a standard 100mm hub to a Boost 110mm hub using Mavic adaptors.
A Boost hub has the hub flanges 10mm further apart which builds a stronger wheel. Another consequence is that the disc rotor is also moved outwards.
As such Mavic do not provide adaptors which support this re-configuration.
Mavic have produced a short document explaining this – Mavic Boost
There are kits available from other manufacturers which include spacers and adaptors but of course these will not be supported by Mavic.
