Unlike a 29er, it took almost no time to adapt but you can definitely feel the rolling & 'suspension' benefits of the bigger hoops. 10 minutes in & I felt right at home.

The frame itself took a little getting used to as it's so flexy in the front end it has a sort of 'fuzzy' connection between the saddle & the bars but you get used to it & it actually becomes a positive part of the ride (as long as you don't mash on the bike...).

Nice!
Looks like a fun bike with good kit. (bar the rear qr is that home made? haha)
Think I'll end up on a 650 in the near future, seems like they have solved some of the 29er issues with the smaller wheels but have all the benefits that 29ers should have in theory.
How do you go with tyre choice? I know when 29er's started out it was slim pickings until the big brands got in the game.

Nice looking build, the seat post looks really nice as do the skewers. I'm really happy with my 29er's so not sure 650b is for me , but I know people who love them.

What do you put the flex and fuzziness down to ?

Guessing the Ti bars and Ti seat post with a lot showing would be part of that.

Beautiful bike.

Good question. Seeing as this is an XC rig & most 650b/27.5ers at the moment are ~150mm travel 'all mountain' ( :roll: ) bikes, the majority of the choices on offer seem to be in the 2.3" range. I tossed up between the Kenda Nevegal 2.1 & the Kenda Karma 2.0. I have plenty of miles on both. I went for the 2.0 Karmas & am glad I did. They seem to be baggier than an equivalent 26" tyre due to the extra sidewall height.

The pillar & bars are there to soften up the ride but they don't contribute to the 'fuzzy' feel (beyond the 700mm wide bars providing lots of torsional flexing leverage). The frame has a nice, stiff rear triangle but the top & down tubes are tiny & really light gauge. Consequently you can easily flex the head tube 20+mm either side of centre when seated on the bike. It's somewhat disconcerting at first but with a small adaption to out-of-the-saddle riding & time in the saddle it just becomes part of the ride.
