Downsides to me at the moment would be; Proprietary cassettes that only go to 11 (so the 56 is only marginally better than a SRAM 50/10 ratio at 5.09 v 5). If you could get a 10/33 cassette, then that wouldbe great.
They offer 12 and 13 speed cassettes as well. They don't do a 10 tooth but do have a 12 speed 11-40 so plenty of range. Pretty light as well - quoted weight at least is lighter than Dura Ace. Guess removing front derailleur and inner chainring offsets at least some of the extra hub weight.
The quoted weight of the hub is 492g. The thru axle is 72g and switch 14g, so the thru axle is comparable to a standard thru axle, perhaps marginally heavier. And the switch is minimal.
A SRAM Red front mech & battery is c190g, plus say 100g for a chainring and bolts?
Comparing the Parcours Disc and then the Classified ready one, there’s a 50g saving for the Classified one.
So the weight penalty is around 150g or the equivalent of 3 gels đŸ˜‚
Checking the cassette weight, an 11-28 is a comparable weight to a SRAM Red 10-28
Being able to go bigger on the cassette could offset the lack of a 10 cog, but would require a bigger front chainring, with a marginal weight penalty.
