Couple of things, I'd guess you don't watch much cross, or see many cross bikes. At all.

And being extracted by a park ranger is 100% a reflection on the rider. You can do anything on CX bike that you can do on an XC bike. Just slower and with better line choice. Much like running rigid and semi slicks. Sometimes slower might even be running. But we do that in XC too......

I see CX bikes on singletrack regularly.

One of them is under my friend, who is a pro MTB racer. Despite that, he has to pick his way down descents at half the speed he'd do them on his XC bike.

Point being, a "light" bike is not necessarily a "fast" bike, unless you ride nothing but rail trails and pavement. There is a reason many pros, at both the WC and regional level, have moved to more reliable, heavier bikes. The days of the Margarita Fullana friendly dirt road races are over.

I'd love to see someone on a CX bike do a downhill, steep rock garden that has drops.

I have had my fair share of wipes on a pair of MCFK bars and no cracks, but a small chip. Have friends that have had perfectly good, uncrashed Eastons snap off and crack Enve's in a slow speed tip over. Bad things can happen to any gear that is not properly maintained or inspected prior to use and especially after any sort of accident.

But very few can ride a bike like Barelli.

That was steep and rocky? Seriously?

That's a BMX track in the woods.

You wouldn't see many riders doing a DH on an XC bike either. And if they were, slow and steady!

I've gotta say that even though the 740 Enve tested close in stiffness to the 700 MCFK in Fairwheels test, after switching to a 720 Enve I noticed the stiffness compared to the old 700 MCFK. Did notice the 36g weight.

Agreed, while mine is just a 26er (so yes inherently lighter - although my relatively budget wheels weigh the same as quoted for his 29ers), my alloy framed home built on a budget (sub £800) FS is lighter than that on it's winter Nobby Nics.

Killer set-up and weight. Need better pictures though!

Hope you don't do any drops. I'm a weight weenie too, and I understand those are production parts, but that's really pushing the good sense envelope.

How did LS sealing went compared to SS? I plan to go SS both front and rear, but extra weight saved looks attractive, as long as SS provides reasonable tubeless setup. This year I had a great dissappointment when X/Raceking RS failed to seal after several weeks using Stan's, no way I'd like to experience something like that again.

@UpFromOne: No worry. I did som pretty tough racing on it, already. Rock gardens, steep and deep drops and jupms.
I spoke with Extralite guys and they understand how though the present XC and marathon courses are.

@Klaster1: sealing the LS version was not a problem with Stans sealant. I took maybe 10 minutes longer to seal than SS version but since then no leaks. Works flawlessly. I have been trying Race King RS version, too. I was able to seal it. But the Race Sport version is not intended for tubeless use. The sides of the tire are so thin and weak it cannot withstand any touching of rock or any obstacle. The side of the tire ruptures and the sealent will not repair it.

Yes, today's XC seems to be yesterday's Enduro!
