I pulled 42 of these out of one tire
I have changed tubeless tires and discovered dozens of thorns in the tire but it never went flat.

Low pressure helps with climbing and rear wheel traction. You have to play with the pressure, too low and the tire will squrim out from under you, too high and you will skip off little rocks and roots.

With either the thornproof/sealant setup or tubeless/sealant - when something finally kills it and you have to put in your spare tube, you will spend most of the time clearing thorns from the tire so the spare tube is not immediately destroyed. The record was about 45 minutes time from stop to ride away.

Its very possible. I'll never forget the time I almost had to spend the night in the woods because of unfamiliarity with an unmarked mtb trail system. We rolled back onto the main entrance road well after 9pm. This was back before GPS was common, so I say bring it and make sure you turn it on before leaving the parking lot.

So, there I was...cranking out the 140th mile in 3 days of commuting on Hunter AAF. I check my mirror and there's another bike way back. I keep cranking...I check the mirror again after about 100m and this guy is closing...fast.

And, he's on a tricycle.

I was already spinning 100rpm at 15mph into a 15mph headwind...I went past LT..and watched as this dude...on a TRICYCLE..passed me (I was gasping).

He was in ACU's and just spinning at about 70rpm..as he passed, he looked over at me and remarked: "wanna race?".

I gasped: "no"

As he pedaled merrily away, I noticed the battery pack on the rear axle. It was a huge battery case.

I can't beat electric assist (at least not after 3 hard days of riding).

Catch me after a couple days off the bike....well, then.

Anyone else seen electric assist bikes? I read in Bicycling magazine that they're starting to trickle into the rental bike fleets. Wave of the future?

80% of the delivery guys use electric assist bikes here in the NYC. Some of the electric bikes style and size practically qualify them as a moped. Also starting to see more electric bikes at commuter stations as commuters ride them to station instead of driving. Curious to see how the electric bike segment will play out. Though to be honest, I grumble a little when I see an electric bike in a bicycle lane.

Yea, that is something I don't always remember to do.

Yep. Been there. During the mid day sun riding withlacoochee state forest. Glad I brought along my etrex with truck marked as waypoint and also glad I had over 70oz in my camelback. Somehow got off the bike trail and on the running trail. Lost for hours and it was hot.

Its real hard to ride 'easy enough to not break a sweat' when the wind's coming straight at you at 20-30mph. Managed it, but had to cut my ride short to keep it right at an hour.

Last nite at UW Hockey I was paying for my ride Wed. No air. When I did stretch it out, it took twice as long to recover.

Ankles are sore today from the fins.

Oh well. I had fun.

Been years since I rode the paved trail. The offroad trails , unless there was a recent rain, are usually sugar sand with lots of ups and downs. It was brutal being lost out there.

I took my Trek X-Caliber on its first outing today, riding the dirt trails at Wekiva state park. Some observations I made along the way:

1. The stock tires are worthless in Florida sugar sand. Traction was almost zero. At times I had to dismount and walk it, as pushing on the pedals would just cause the rear tire to spin.

2. The stock tires are also worthless in wet sand. It takes mere seconds for the shallow treadblocks to completely clog up. At that point it's like riding on slicks.

3. The bike acquitted itself well in all sorts of terrain (except sugar sand). It had rained shortly before I got there, and the exposed roots on the trail were still wet and slippery. There were times I was sure I was going to go down in particularly rough sections, but it never happened. I did make sure to have my Go Pro camera rolling just in case, mindful of the street cred I'd earn by doing a face plant and having the documentation to prove it.

4. The hard tail didn't give nearly as bumpy a ride as I'd expected, even when going over roots.

5. Trails like these may be good practice for beginners, but you can't ride them fast enough to get a decent workout. I need to find some hills.

6. Florida does have cactuses!

Try less air pressure.

Sounds like you've got the tires pumped up too high.

Old rule of thumb is you should be able to bottom out the tire on the biggest hit of the day. (same as your suspension)
