New bike sizing for 6ft 1" rider

Hi people,

I'm about to buy a new mountain bike, a Saracen Mantra, but I'm a little unsure on sizing. It's between a L and XL, I have nowhere local to try one out so hoping for some input from riders my size and those with knowledge of Saracens (I have never ridden one for reference).

I'm 6ft 1" and have a 34 inch inside leg, my ape index is positive (reach to height), I was initially thinking a large but thinking the XL would suit better, but still really unsure.

Can anyone give me some advice?

Thank you.

    According to this you are slap bang in the middle for a 19" frame although it's not clear whether that equates to an L or an XL

    I actually meant between a 19 and 21, L and XL was actually another bike I was looking at, sorry about that. It's the Manta trail I'm looking at and I'm right on the cusp of a 19/21 according to their chart. That states a 19 frame is 5ft 10 to 6ft 2, the 21 frame is 6ft to 6ft 3 but none of those take into account reach or inside leg, hence my uncertainty.

    To be honest, I were to spend that sort of money, I'd take a day trip one weekend to somewhere that has stock and try them for size.

    Depends on your build and preferences, if you have longer legs (thus shorter body) you need a smaller frame to match your reach and vice versa.
