BillOdie – I just bought my son the Genesis Core 24 for Christmas.
Great bike with proper Shimano hydraulic disc brakes and a 1 x 9 drivetrain.
I looked at the Frogs as my LBS sell them too. TBH I went for the Genesis without seeing one in the flesh but it was the discs and drivetrain that sold it for me.
When I picked the bike up we compared it to the equivalent sized Frog and the Frog was a bit lighter at the front end but also a lot lower.
This years model also comes with a rigid fork as in your link but the geometry will take a suspension fork. There are a couple of lightweight air forks on the market for 24″ wheel and can be bought from Germany for less than £150 new.
I have just bought him some shortened Sram cranks from the USA which will then get a narrow wide chainring fitted. Probably a 32 as it currently has a 34.
Whether I put my spare 10 speed XT kit on it is another matter. A set of carbon bars and seat post will see a chink of weight knocked off too but I must try not to get carried away! It’s the bike that I never had when I was his age.
It’s genuinely a great bike and he has done 10+ mile rides over Cannock with ease.
