Big wheels on small bike using road tyres

I decided to see if the wheels off of my 29er would fit on my 26" hardtail using 23mm road wheels.
Super motard! the frame could accomodate a much bigger tyre but there is far less clearance on the forks, maybe 15mm from tyre to arch.
It was too late to try it on the road this evening but I'm looking forward to hitting the west coast highway on the 23mm wide 700c tyres at 90 & 110 psi.

I like it

Now I'm thinking about doing the same with my On-One Inbred slot-dropout commuter/utility bike. Have to test out clearance on the seat stays arch, heaps of room everywhere else.

I've been running that kind of setup but using roadi rims laced to mtb disc hubs for 3 or so years on my Cannondale hardtail. It works really well, eh? I get some funny looks sometimes, but I really like the way the bike looks.

You've just gotta watch the road surface more closely: I trashed a rear rim on a square-lipped pothole I didn't see until too late. (Thankyou Mosman Council Sad ) 23mm tyres aren't real forgiving. But they roll really well and with good rubber like Conti GP4000s Black Chilli wet weather grip is excellent.

Watch out for the loose stuff, its unforgiving!

On-One and Cotic - very reminiscent to me of the Singletrackworld forums.

I still miss the Kinesis Crosslight cyclocross bike I built, it was so versatile I could ride it on most XC trails as well as the road without changing tyres, but unfortunately it was stolen.

Jeronimo, I know what you mean.
I bought it in the UK as a frame after seeing Cy (Mr Cotic)with the prototype at Mountain Mayhem back in 2006. I'd been changing bikes or frames regularly and wanted something that would last & do everything. With up to 130mm fork capability & weighing in at around 1.5kg & with the great springiness but resistance to metal fatigue or corrosion associated with Titanium I put a deposit down there & then (despite Cy telling me that there was no production date).
About 9 months later I had no4 off of the line.

I must admit it took a while to get the bike just right as small changes in the stem & fork length made huge differences to the handling.
Now with a 15mm through axle Reba 120 pop & a 100mm stem I think I'm there.

The On One stuff is also great vfm & represents the slightly off centre all year bog riding scene that is the norm in the UK but imho is not in the same league.
BTW, my new bike is an On One Scandal 29er!
