oh yeah. took the back wheel off today, it was really tight in the frame, and was a mofo to put back on.

Its a 7 speed mtn hub, so its likely 135mm. I had to spread the frame about a full CM to get the wheel in. this took two people.

a made-in-USA road frame from 1977, think that was 5 or 6 speed? the midrange factory builds had a "Suntour Procompe 14-28", anyone know if that was 5 or 6? per Sheldon, a 5 speed road is 120mm, while a 6-7 speed is 126mm.

I note that with the wheel installed, the stays are somewhat bowed outwards but its an even curve, there's no bend or kink.

I bet I should pull the wheels and do a Sheldon 2x4 frame bender to get it a lot closer to 135mm, then eyeball+crescent wrench the dropouts to approximately square. trouble is, I have tomorrow to do this, and its a work day. Ian's leaving early Thursday AM.

Admittedly though, "mediocre oblivion at the bottom of a pint glass" just about sums up my XC MTB racing abilities.

It's not the 70's anymore. High tpi tires are available in puncture resistant carcasses, just like low tpi models. Years ago, you didn't have many options. Today, technology and selection are far beyond the imaginations of yesteryear.

I ride high tpi tires all over the place on rock roads. If fact, I seek the gravel and dirt roads of the area for their tranquility. I have hundreds of rock road miles on the current tires on my Tricross. There's not so much as an abrasion on the sidewalls and they've proven very durable with 120tpi.

On Panaracer tires, I know Sheldon Brown was quite fond of them, but, I don't see much mention of them from people who ride modern bikes farther than the local coffee shop.

Paselas with "TourGuard" rule. Sure, they look a little frumpy with that nice brown sidewall, but I've got over a 1000 miles of touring, hundreds of miles of gravel road racing, and god knows how much commuting and gravel road "training" on my current set. Not one single flat. And it's a nice riding tire that gets pretty good traction in weird conditions too. And they're cheap!

Don't bend your frame, it will break and poke your eye out and then you will get run over by a bus!

Deerfield Dirt Road Randonee is this Saturday. The Fargo is almost ready, but I'm not.

Back in January when registration opened I felt all ambitious and signed up for the long version -- 112 miles, ~16k feet of climbing. The last two years I've done the easier 62mi/8k route.

With the shorter ride I found that I didn't need a very high level of fitness. Food, water, patience, and a 28x27 low gear got me through it. I doubt this holds for the long ride, and I'm worried that I'm not fit enough for it. But I'm going to start it anyways, with the knowledge that there are bailout options if I need them.

Just think- after that, you'll need to find something harder to do.

Looks like it should be a pretty cool ride though, enjoy!

Bike pump....years ago, bike pumps used to have a flexible adapter that you screwed into the valve on the tube and into the pump itself - remember them ? Does anybody make them still for Presta ? I dislike the 'new' pumps that attach directly to the valve itself - I just can't get the hang of them.

Anybody make the old type ? I need a new, bigger, frame pump and before I buy the type I dislike, just wanted to run this by the collective.

Cheers

Lezyne make them. I carry a Lezyne Alloy mini pump on the bike. The hose in pulls out from the inside of the unit. Will work with types of valves.

hope this helps

IIRC the highest TPI out there right now is the Vittoria Open Corsa at 320tpi. For a lot less $$ the Vredstein Fortezza rides almost as nice, and is a lot more puncture resistant.

I'm riding some Conti GP4000s on the Fetish. Ride OK. Nothing to write about either bad OR great. I liked the old brown sidewall Grand Prix tires better. Natural rubber. Stuck better in the rain.

The other wheelset has a mix of an Axial Pro on the front and the Vredstein on the back. Haven't actually ridden that wheelset cause its for the Crosshairs and I've got the knobbies on it.
