Description

Why We Like The Nano TCS Light FR Tire

The Nano TCS Light FR Tire is built for reaching top speeds, whether we're grooving on hard-pack singletrack, gravel roads, or smooth tarmac. It features SG2 puncture protection for durability, but that also improves air retention and eliminates sidewall seepage. Its high-volume 40mm casing allows for running lower tire pressures while still reducing drag. A raised, consistent centerline tread minimizes rolling resistance, and staggered knobs provide reliable traction that doesn't make any compromises for speed.

Very good all around tire

Familiarity:
I've put it through the wringer

So good that I bought a second pair. I rode these several days a week on one to five hour mixed gravel adventures. They made it through a year before wearing out. My favorite rides take me up gravel, over pavement, over mountains, and back—no terrain is too much for this tire. This tire performs well on gravel. It rolls well on pavement (not like a road tire, but better than most mountain bike tires by far), is a little loose turning on pavement, otherwise, a great handling tire. Good comfort, tubeless, at 30 to 35 psi on gravel roads. (I’m 6 foot and 165-170 pounds.)

Real Good

Familiarity:
I've put it through the wringer

These things are sweet. They're grippy on dirt, roll fairly fast on pavement, and they'll shrug off some serious hits without flatting. It was painless setting them up tubeless on WTB i19 Asym rims with one layer of Gorilla tape. They're not the longest lasting tire, and the 40mm size will be too big for most race-focused 'cross bikes, but they're absolutely worth running if they suit your intended use.

Thoughts on these as "monster cross" tires on 29" rims? Can't find any fit issues...am I missing anything (not planning to run them tubeless at first)

Fast CX tire with good grip in the sand

Familiarity:
I've used it several times

I was looking for a CX tire for the sand/hardpack conditions here in SoCal. I had used the Kenda Happy Mediums (700x40) in the past and liked them, but wanted a tubeless setup. I had heard positive things about the WTB Nanos. These were my first WTB tires, since my "old" 26" Velociraptors. I installed these tires on Stan's Iron Cross wheels with 1 strip of tape and about 2 ozs of sealant per tire. I used the regular Stan's method, and got the beads to seat right away with just soapy water and a pancake compressor. After adding the sealant, it took a few rounds of shaking and spinning to get them to hold air overnight. Now, they hold air perfectly for days. I've done a few rides on these now, and absolutely love them. I run them at about 35 PSI (I'm about 155 lbs) and they feel like tubular CX tires. They're fairly fast on the road, but shine in sandy conditions. I've also ridden a decent amount of singletrack on them and they hold the corners well. I've attached a photo of them on a recent ride past the original M.A.S.H. TV set near Malibu Creek SP. Overall, a great CX tire for adventure/gravel rides!
