What do you carry to remove tight tubeless and procore Presta valve locknuts?

folding spoke

Wait what? Folding spoke?

Depends on the ride what I carry, big epic out in the boondocks gets a bigger more extensive tool kit. Backyard rides on Fromme get a minimal tool kit.

Euros/Pounds

If you have a bank account that has no ATM fees, withdrawing money from any 'plus' ATM machines in the respective country has generally given me the best exchange and lowest fees.

This has works. Africa, Europe, South America and the formerly great nation of the USA and a debit card.

The decline of forums

Why is this true?

We need a giant reset in the West. Education is failing us tremendously.

People need to learn how to be person/human. Critical thinking, etc.

I don't know why it's true. I have no idea how to change it.

The decline of forums

There is a trove of amazing technical information shared on forums if you spend the time looking, reading and digging.

I am thankful of those that share their build projects and technical information online. But you only get out what you put in, so remember to give back and make some quality posts of your own.

You're never going to change someone's political/social view arguing on the internet so why bother wasting the time. You're likely receive a useless meme to your well researched.

Saint/Zee vs. Magura MT7/MT5 : mini review

I weigh 230 pounds right now and they just work.

I see your Fiver World Series training is right on target.

you're building an adhoc

Yes some similarities.

The Xprezo's leverage curve has a different shape (progressive - linear - progressive), also with main pivot placement we end up with much different AS curves. I've got a bit more anti-rise on mine but chain growth comes out the same.

Oh and mine's a wagon wheeler.

That's taking suspension geek to the next level, very cool. Linkage driven single pivot? Looks like just over 100 percent antisquat, looking at the pivot location. Just moving the frame shock mount location a few milometers makes a difference in progression rate does it not? Almost makes me want to go buy a welder.

Yes just over 100% as with a 32t chianring and 42t rear cog.

Correct a few mm on each pivot can really change things.

Here you can see that I am bench marking against the new Transition Patrol Carbon, one of the first bikes to be designed around the metric RS shocks. My earlier iteration had the shock sitting lower in the frame and I was playing with going trunion mount. Decided to ditch the trunion mount and move the shock up higher so it involved less fab work at the bb/dt junction and I get a slightly different LR curve with lower initial progressive spike. I think this final one is what I am going to move forward with.

nice looking design , what travel roughly ?

Will be 136mm travel frame paired with a 150mm fork.

Still a possibility that I move that up to 140ish.

As with the way Kona designed their Process line I am not designing to a specific travel but to a LR that I want to hit within a travel window. In this case I'd be happy with anywhere from 130 to 145mm of travel so long as I get the lr I want with the shock size I've picked.

It's currently designed around a 210mm x 55mm metric sized shock.

455mm reach huh? How tall are u?

About 6ft, a hair under if I've not shrunk since the last time I measured myself a decade ago.

very cool. how are you fabbing the linkage bits?

TBD.

Could be hacksaw and a file, or get a friend (Biggles604) to machine them.

speaking of garage jalopies, what's the status of your latest build? something like the starling 29'er perhaps?

Just ordered some tubes for this today.

The geo on this isn't final, but it's allowed me to work out the kinematics on the linkage.

Lots of stuff to work out in cad for the linkage and the shock mount/pivot/bb/downtube junction.

I don't think I'll go back to 2x. With 1x it makes designing and building my garage jalopies much simpler. With a 1x drivetrain you can get a good anti-squat without needing extra linkage around the main pivot.

The Decline of Vancouver.

I need to stop reading the news in the morning. It only makes me angry at the moment.

Don't read it before bed, it just makes you toss and turn most of the night.
