Official MTB Thread

I think this thread is necessary as the number of 1wd knobby-tired lung-burners on the forum has increased.





Has anyone been here? MTB Park-Ogden

[TRD270]

Ogden? Isn't that where you go to have your mountain bike stolen?

[Kevin]

I don't know about gap jumps. I can't even bunny.

Part of Ogden for sure.

I don't know about gap jumps.  I can't even bunny.

You have to run before you can walk.

I've never been to the Bike Park in Ogden. I do put in a little bit of time at Corner Canyon in Draper and Lambert Park in Alpine.

I lost my crank arm for the second time on the Klondike trails in Moab last weekend. I got it home and cleaned it up really well, it doesn't look damaged so I put it back together and torqued it carefully and I'll give it one more shot before I'll have to spring for a new crank set.

Thing is, I really want to go to a 1x drivetrain and I can't afford to do it right now so I'm going to get as much life as I can out of this silly POS.

[Kevin]

Anybody want to ride Sunday morning? Thinking about Corner Canyon, but whaddeva.

[MacKay]

I think I'm going to ride there on Thursday. Probably early morning, or maybe after work.

Define morning

[MacKay]

I need to be at work at 8:30 a.m. So probably 6:30 a.m. at the trailhead? This is unless my newborn has a bad night...

Sometime between "why is it so dark and WhereTF is the damned trail" and "OMG SOMEBODY SAVE ME FROM THE FIERY ORB OF DEATH"?

I'm no good Thursday morning, working in Layton at 0800.

Josh and I tried to ride Corner Canyon yesterday.  Busted my derailleur hanger three miles in.  Coasting.  On flat trail.  Not pedaling, not shifting, not running into rocks.  Snap.  That's two for two, if something breaks the next I ride with Josh I'm going to start suspecting foul play.

On a side note, it's ridiculous how much they want for one of those little hangers.

[dutchman]

That seems suspicious...

[TRD270]

I think the trooper sabotaged it

[Kevin]

Ghetto tubeless!  I've seen it on Youtube so I'm totally an expert.  We'll see if it works.

Stripped the wheel down, removed the rim strip, cleaned it with degreaser and then brake cleaner.


Several companies make replacement liners, but this is ghetto.  Cut a strip of Gorilla Tape just slightly wider than the inside of the wheel.  Pull it on, tight.  Tighter.  Tighter.  Oh baby.  Overlap the stem hole by several inches on each side, they say.


Press the tape down hard (oh baby) on the edges, make sure it's well seated.


Again, you can buy replacement stems specifically for the tubeless conversion.  Again, f@$& all that, I don't have time to do this crap right.  I hacked this stem out of an old tube I got tired of patching.  I tried to trim enough rubber that it sits down between the the wheel walls well but leave enough that it has a chance to seal.  I may have trimmed too much?  One way to find out.


Cut an x in the Gorilla Tape just large enough to slip the stem through.  And then take a picture of it, because I forgot.

Moment of truth, can I seat the bead?


Yes, yes I can.  I can hear a little air escaping at the stem, but for the most part it's holding.  Part two later, I'm still researching exactly which sealant to use.  But at least now I know it'll (probably) work.

So... if you put a small hole in the tire, will it leak?

Advantages of being tubeless?

[Kevin]

So... if you put a small hole in the tire, will it leak?

Advantages of being tubeless?

The sealant stays liquid inside the tire, and theoretically seals any leaks.

Advantages are less weight, lower PSI with much less risk of pinch flats.

[TRD270]

Advantages of being tubeless?

With sealant it should seal and not leak with a small hole.

Biggest advantage to tubeless is being able to run a lower pressure without worrying about pinch flats. Slightly less rolling mass, and small punctures should seal up

[TRD270]

Want to throw this up here as well if anyone is interested. I recently bought a Diamondback Sync'r, it may be responsible for sabotaging Kevin's bike. I've decided to buy a full suspension, and do some upgrades to my older hardtail instead. It's an XL frame, fun bike, few scratches from Kevin laughing at my clipless fails. 50ish miles on it

Asking $750 (new retail is $1200)

I understand now.

You get your bike fixed Kevin?

You get your bike fixed Kevin?

Parts are in the mail.

I want to do a day trip to Strawberry Narrows this weekend,
https://www.trailforks.com/trails/strawberry-narrows/
if anyone is interested.
I plan to park at the Marina then ride out and back.


Also interesting for a shuttle ride is Willow Creek
https://www.trailforks.com/trails/willow-creek-10843/

[Kevin]

I really want to canoe the Narrows.

Which marina are you starting at? There's one on both ends.
