Right Speedmax SLX size

Hello there,

i'm looking to buy a speedmax cf slx 7. I'm 169cm (M) with 77cm inseam and the recommended size seems to be XS. I do own an endurace cf 7 size S, it seems to be a good fit (i wish the reach was a bit shorter, missing few cm to be completely in agressive position but happy with the position overall). Do you have any feedbacks/experiences regarding the sizes of the SLX 7 ?

Thanks
