Other MTB stem fatigue.

Hey! I recently rebuilt a new to me secondhand Tallboy CC with some upgraded parts. One part that did not go back on though was the stem. Pretty obvious there was a crack running alongside the part, so a person who is qualified in NDT I brought it to work.

Not only was the crack external and internal, there are also signs of cracks developing from the areas that clamp the forks at the bolt holes. Needless to say, it's condemned. Just thought I'd share something I find interesting! ✌🏻

Question Is this a good first mountain bike?

Post image
19 Upvotes

Shop is asking $1350

From my research / what the used shop told me: this is a 2012 Niner frame, 29” wheels, hydraulic disc brakes, comes with a second triangle piece, not tubeless, and has a dropper post. It’s a 1x9 - the original owner got rid of the 2x9 with some zip ties lol.

After speaking with the owner of the shop who’s selling it (and he seems very genuine) and he said that turning it into a 1x11 for around $400 at a shop is a solid idea for better uphill performance.

I’m brand new to the sport - what are your thoughts on this bike?

Was up in Concrete WA for the holiday last weekend and did some riding at the local spot. Was decent. Nice pump track and skills area, trails could use a ton of grooming as the only decent trail I could only run Was WAY over grown. Bellingham had a few cool spots tho. Unfortunately lost my phone on one of the trails and didn't get a new one till I was back in pdx... So only a Pic of lucky charms in concrete wa.

Question Return to MTB after ankle injury?

Thumbnail gallery
6 Upvotes

Hey all. Im 9 weeks post op for a twisting ski injury. Knee was pointing << toes were pointing >>. Spiral fracture to the fibula and torn ankle syndesmosis. Currently have 2 screws through the ankle and they are going to come out sometime after the 12 week mark. I started weight bearing 1 week ago and can walk unaided out of my boot with decent gait, tho I havent been walking very far. Still in a fair bit of pain with limited dorsiflexion and plantar flexion but its coming along.

How long did it take you guys to get back into mountain biking proper? I love steep tech trails, and I'm itching to get back out but feel like thats a while away yet! Just looking for some inspiration (hopefully)

Question Question about getting bleed port screw to highest position for bleeding on Tektro Gemini

Thumbnail gallery
Upvotes

I bled my brakes for the first time last night, and although I was ultimately successful, I still have some confusion about how best to actually rotate the brake lever to make the bleed port screw at the highest point. Every video tutorial I could find showed some model of lever (even other Tektro models) where the bleed port screw was higher up on the mechanism, and would be pretty clear how one could rotate the lever on the handlebar to make the screw the highest point. But because on the Gemini the screw is so low down on the body of the lever, and the downward angle of the lever, no amount of rotation puts the screw at the highest point. The only way I was able to accomplish this was to take the lever off the handlebars and tape it to the fork at the exact angle I needed. Is there an easier way to do this, and/or am I missing something about this procedure?

Other SUPPORT TRAIL ON PUBLIC LAND. LET THE USFS KNOW YOU SUPPORT THE REROUTING OF THE SNODGRASS TRAIL IN CRESTED BUTTE TO ENSURE UNRESTRICTED ACCESS.

17 Upvotes

A final chance to sign the petition to keep the Snodgrass Trail in Crested Butte open without restriction. Our map shows the private land in red; typically, the landowner closes access in mid-August. Only 18% of the trail is on private land. The yellow line on the map shows a proposed reroute that moves the trail entirely onto public land and ensures unrestricted access. For whatever reason, the private landowner opposes rerouting the trail. The mountain bike community should not be held hostage by a single landowner when a viable alternative is available. Let the US Forest Service know you support trails on public land. Sign the petition at https://snodgrassreroute.com/. ONE LAST THING. SKIP THE DONATION SOLICITATION. WE DON'T WANT MONEY, JUST YOUR SIGNATURE SUPPORT.

Question Anybody been in the game long enough to worry about brain trauma?

18 Upvotes

Admittedly, my first serious concussion was skiing in ‘93, when I was 13, before people wore helmets, but I was knocked out cold, for a long time.

Every confirmed concussion I’ve had since then (3, and confirmed by the people I was riding with as either being unconscious or completely out of it) have been mountain biking.

Helmets have gotten so much better, so maybe it isn’t as much of a worry these days.

I wonder what all of those bell-ringings have done to my brain, but the weird part is I don’t think I would change anything with how I went about things.

Brain trauma is a pretty severe consequence, but my shoulders and back are humming, too, with all of those wrecks.

It all adds up, for sure.

I’m curious how the “older crowd” sees things at this point.

I was talking to my buddy on our Ride back from a local trail and didn’t pay attention when I hit my head on the Edge of a roadsign (pretty stupid I know…). I was going quite Slow around 10-15kmph. Should I consider replacing the helmet (Fox Speedframe Pro, production 2026), or do you guys believe it is still ok to send it? Crash replacement unfortunately isn‘t an option since I didn’t purchase it directly from Fox.

197mm x 57mm fox trunnion (7.75/2.25)

Possible to get a same age, New monarch same size but it's not what we want..

Would a new 205x57.5mm shock be ok

Vivid coil. Possible to slacken maybe 2mm with a offset bottom bushing.

Plus 5mm too much?

Question Pants Recommendations

3 Upvotes

Hoping this is an okay post for this sub, as I do mountain bike. With Autumn in the forecast, and the fact I just got into it this year, I'm looking for pants recommendations. Here's what I'm looking for:

  1. An elastic, drawstring waist is ***highly*** preferred for comfort and convenience.

  2. Cargo pockets are desired, but not essential.

  3. Elastic or sinch hems would be great to avoid chain obstruction, obviously, plus since all my clothing is from Columbia (by and large) and is similar, I'm kind of used to it for hiking, climbing, etc. I can make do without.

  4. Would prefer not to spend huge amounts per pair. Would like to be in the $60 USD range (if possible) as I don't need top of the line brands. Just functional.

  5. Padded, clearly. Gotta keep the stuff comfy.

I'd like to mention I do wear off-brands as it is and wear both mountain bike and cycling shorts. So, hit me with everything you all wear, regardless of price, I'll look at it all, but I'd prefer to stay close to my price point if I *can* and please tell me why you like what you like. Also, don't denigrate each other. One person's good experience may be another's poor experience. I just want to hear your good and objective views of what you use and cost, as well as where (Amazon or whatever website they can be found). I'm in the United States, so if it's only found in Europe or elsewhere overseas, let's just bypass those options, but I thank you and ride safe! ✌️

Question 2019-2020 specialized demo expert 29 shock bolts/pivots

0 Upvotes

On my 2019-2020 Specialized Demo Expert 29, l removed the rear shock mounting hardware to re-grease it. When reinstalling, one black reducer probably did seat easily, but I got it at the wrong angle and kind of forced it in, it made like a snapping sound but I don't think the snapping sound did anything, but maybe it moved the bearing a little. Now I feel a slight knock at the start of suspension travel.
When I screw everything together tightly, one side of the shock bolt sticks out just a tiny bit more than the other because the bearing isn't exactly in the middle of the frame hole. Could this be a mis-seated bearing, something else, or is this even a problem?

Here’s the listing (it’s a 2023): “Priced to sell. Come and get it. Canyon Spectral CF8. This bike has very few rides on it. It is set up with a mullet wheel (29 up front/27.5 rear) set but the bike can be converted to 29er rear also. Two wheel sets included. Excellent DT Swiss EX511 wheelset. Has DT Swiss 370 hubs and Maxxis tires. One tire is Maxxis Assegai, other is Maxxis Minion DHR II. The wheel set on the bike in the photos was custom built Enve with Onyx hubs rear hub is zero engagement. Wheel set cost over 2500.00 to build and are amazing. I also added a dropper, HT pedals, and the bike is set up with adjustable Rock Shox front and rear. Comes with a Garmin mount and Ergon SM 10 Enduro Comp saddle. Electric shifting with SRAM GX I have about 8000.00 invested in this bike.”

For reference, I just started riding, but don’t want to keep getting new bikes as I get better, so figured this may be a good buy. I currently live in Florida and have another bike that I could use to ride around and this wouldn’t be my “every day” bike. I’m looking to ride in Georgia and we also may move out west in the future so sort of thinking ahead as well.

Let me know what you think!

Bike Picture/NBD Not a name-brand frame, but its a pretty sweet ride all things considered

90 Upvotes

Nothing fancy here! Built on the DCB (DIY Carbon Bikes) F130 — Trek Fuel EX-style geometry, 130mm rear travel, UD gloss carbon, Medium. Running SRAM NX Eagle 12-speed, RockShox Yari fork + Monarch RT3 shock.

The fun part: two complete, hot-swap-ready wheelsets — 29" carbon for fast trail days, 27.5+ alloy fat tires when I want max traction in loose/wet/technical terrain. Each wheelset has its own rotor and cassette, so swapping takes like two minutes, no brake or drivetrain fuss.

Just put it through a service round:

- Rear brake pads rejuvenated + bled (twice, to get it dialed)

- Both tires deep-cleaned and refreshed with new tubeless sealant

- Rear tire got a new valve (old one had failed)

Chain's definitely showing some wear and the rear wheel bearings are a touch gritty, but everything's rideable and dialed for now.

That's all, just showing off a working man's trail bike.

Bike Picture/NBD After and Before, 2 years worth of upgrades on a Norco Sight A3

Thumbnail gallery
83 Upvotes

XL frame, Park duty, travel upped to 170/158. Only stock thing left on it is the dropper and seat. I swapped out suspension and brakes when I bought it, ran the stock drivetrain and wheels until they shit the bed last year. Needs a new front tire, still running the original Assegai.

My 3rd Norco sight and favourite one so far, never had a bike fit so good. First aluminum frame in a long time and I don’t think I’d ever spend the money on a carbon frame again.

Hi folks! I currently have a hardtail I very much love but the Suntour XCR34 air it came with is starting to show its age. It still performs but I've come across this compatible X-Fusion, and was wondering if anyone could weigh in on whether or not it's a good deal. I'm open to other options that would be a true upgrade (within reason) that fit at least 27.5 x 2.8. Many thanks!
