I’m just under 6’1″ and have had a Tallboy LTc for the last couple of years. Normally run either a 70mm or 60mm stem and 760mm bars and I like the fit – I have a liking for really steep techy natural trails and find that the bike has a nice compact feel….for the type of bike it is. I’ve demo’d a couple of TBc’s, and in a perfect World, would love a TBc and my LTc. I found the TB’s much easier uphill, but preferred the balance of up/down capability of the LTc for rough natural trails – if I was just doing trail centres, I reckon a TBc would be perfect.
FWIW, my OH has a large Superlight 29, which is exactly the same geometry as the TB – she’s running a 55mm stem and 785 bars and it feels great; only notice the handling getting very slightly ‘edgy’ feeling at high speeds over rough ground – but even then it’s not that bad. If you can bag a demo of a L and XL TB, it might be worth a go.
