Specs are a bit thin on the ground but Favero have been teasing this for a few weeks and today I got the confirmatory public email.
My understanding is that we have a new dual-sided or single-sided PM, like the BePro, but this time with both ANT+ and BLE connectivity (unlike the ANT+only BePro)
The charging mechanism has been changed away from Micro USB and I would imagine the profile of the circular ‘hub’ has been modified to reduce the risk of cleats touching it.
I believe too that the installation now requires no special tools.
Those do all sound like improvements although I still consider the BePro to be perfectly fine for my usage.
This probably explains the recent lack of availability of the single-sided BePro as production of the ASSIOMA ramps up for a Summer/Fall release.
