That looks awesome. Good luck!

Ya know, Paris-Brest-Paris is in 2015.

Solo. Would've been nice to have company tho.

Beautiful day despite the wind.

I never met one 'till I moved to Colorado. Then I got to know them very well and very quickly

The most common name here amongst cyclists is the Goat's Head, but the species name is Tribulus terrestris. They creep along the ground as they grow, widening their path of destruction and are really hard to see unless you're looking for them and moving slowly. I couldn't get in a single ride without a flat. That's when I went to the tire strips and gooey tubes - nary a flat since. I'm taking a weight penalty, but it's that or fix flats every day.

I keep a good supply of Park GP2 glueless patches on hand. In almost 20 years of mountain biking, I haven't had one fail. And they're soooooooo easy to put on. They're itty bitty too and the glue's already on, so there's no mess. They also come with a little slice of sandpaper and a plastic box it all goes in. It's all about the size of a postage stamp, only thicker.
Hmm, I tried the gp2s, didn't have good luck with them. . . . they'd last one ride, then the heat cycling would pop them off (I guess). Went back to glued patches, never had a problem with them.

Bizarre. Maybe it's a matter of method.

I scuff up the tube while inflated to about where it's gonna be. Then inflate it as much as possible to reflect where it'll be in the tire. Then put on the patch and mash the snot out of it. Then put it all back together - never fully deflating the tube.

The patches are flexible, so putting one on with the tube deflated or overinflated might make the patch wander and fail. Bubbles, debris, and/or ridges will also botch the job. But with properly applied patches, I've had great success.

Might have something to do with tire pressure too. I rarely run over 35 psi. Haven't run one in a 29er tire either - always 26. I'm hoping my strips will make it a non-issue.

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.

Nice

Took part in the old part of the town, 7 km per lap X 5 laps

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.
