Worth giving Curtis a call, they’re very helpful.
For me I was considering one as an alternative to the Marino I’d ordered but which no progress had been made on. Then Marino U.K. got involved and have pushed my order along quicker so I stepped back from ordering a Curtis as it was way more money than I really wanted to spend.
That deep blue is some kind of blue candy they do – looks amazing – it’s more expensive than their standard paint I think.
I’ve gone 650b as my full suss is also 650b so they can share / swap tyres etc – plus the forks are the same travel so can be moved between them too.
I’ve not ridden a 29er I love yet – enough to move from 650b. 29ers are almost definitely quicker – the few I’ve had a go on have given me PB’s on Strava at times when I thought I haven’t even been that quick. More importantly for me though they didn’t feel as playful or as fun. I’m sure in time I’ll end up with one that hits the spot, just not right now. I imagine I’ll keep a 650b hardtail for playing on / for the agility – but my main trail fs might end up being 29er at some point.
Mullet bikes seem to be a thing now so quite a few bikes still have a 650b rear wheel – so I don’t think parts are going to die out that soon. I guess forks could be an issue in time, but I don’t see it yet.
Could you test ride some similar geometry bikes in both 650b and 29er and see which floats your boat?
