The Mountain Bike Thread

Dating my self. I'm at least 20 years behind on bike technology. Advanced tech to me was the debate over 21, 23, or 25 mm tires at 110 or 120 psi. on road bikes. With tubes, of course. My mtn bike is close to 30 years old, and the only suspension is the tire pressure.
yea, dumbfounded when I really checked out my daughter's and SIL's (serious mtb'rs) latest rides..wireless shifting components, Garmin Edge computers, electronic suspension, carbon fiber frames, total pkgs just over 20#...bikes that will put a major hurt on a credit card...

Yeah, times have changed. Even the pros are riding 28-32's on the road now along with 1X drivetrains sometimes. I have 38's on my road bike at about 45psi and 50's on my gravel bike (in the photo above) at 25psi. Sometimes, I'll even cram a 2.1" (52) on the gravel bike for AZ since there's a lot of sand and it doesn't feel particularly slow on the road.

There have been a lot of studies that show that fatter and softer is actually faster in many cases due to the physics of rolling resistance.

OK, that's mind blowing. I recall some pretty serious, almost heated, arguments between adherents of 21 and 23 road tires with a guy who wedded himself to 25s as not giving up any speed or efficiency. A while back I did put 28s on my Rivendell, which is built a little more for comfort and touring than speed. And 28s are the max I can fit - not sure if the frame or the wheels are the limiting factor there. Then a few years ago my SIL was telling me that my other road bike (Merckx) would ride just as well and be more comfortable with the tires at 85 psi.

Yeah, 20mm or 23mm at 110-120+ PSI! We really knew how to live on the edge (quite literally) back then.

Could be the brakes too. I made a mistake above, I do have one bike still running tubes - my original long distance bike from 2006. I could probably get 30-32's inside the frame but they won't fit through rim brakes. I can get 28's on by flipping the brake caliper release lever to give a little extra space or loosening the cable entirely.
All the big tire stuff is cool but the two things that have been the biggest benefit and have actually changed my riding, especially as I age are:
1) Disc brakes - work better in all conditions and open up the opportunity for tech advances in wheel/tires
2) Bigger gears - My road bike runs a compact crankset of 46/33 with a 11-36 in the back. Really makes climbing easier on my knees. Gone are the days of a 53/46 and a 10-21... Short crack arms are the rage these days as well. I've been running 172.5 and 170's forever but switched to 165s which would have been considered something for kids or small women in the past after reading about Tadej Pogacar changing for based on biomechanics testing. Noticeable benefit to my knees and balky hip due to the reduced angle at the top of the pedal stroke.

Yeah, maybe the brakes. I had to buy a certain Shimano model that opens wide enough for the 28s, as I recall. Roadies are such weight weenies, it's hard to imagine them adopting heavier disc brakes, let alone those "heavy" wide tires. The Rivendell has a compact crank (50/34) by Shimano, I think. The Merckx is all Campy, which didn't have a compact option when I got it, (it's my only 10 spd) so 39 is the largest inner gear wheel it takes. Both bikes have 175 crank arms. Never say never, but I don't see a new bike in my future.
 
anyone running ebikes care to comment on what they've learned? Rear hub vs mid drive, chain vs belt...?
Along with a relatively large fleet of MTBs, road bikes, and recumbents we have a couple of Tern cargo e-bikes, which are mid-drive Bosch. Everyone I know that's had hub drive has had various problems (some due to their attempts to hack the control systems into class 3). Mid-drives of all stripes just appear to the most dependable, with Bosch clearly leading the pack for class 1. A mid-drive certainly keeps the bike's center of gravity low and 'centered'.

I don't have a belt driven bike, but I'm intrigued by the concept, and particularly when it's used with one of the Pinion transmission systems. Were I still an 'all-weather' bike commuter (now unnecessary due to retirement) I'd definitely own a belt drive/Pinion bike due to its vastly diminished maintenance requirements. The only problem I've heard of with belt drive is handling truly epic quantities of 'peanut-butter' mud, which can cause the belt to walk off the rear wheel cog.

As for such things as disc brakes on road bikes, internal cables, one-piece handlebar/stem, and wireless shifting...the industry thrives on creating extraordinarily costly 'must haves' among amateur cycling enthusiasts by constantly introducing 'innovations' via European racing teams...whose riders (and team mechanics) have very little actual say about what their Shimano and SRAM sponsors require.

It's always amusing to see a 'weight-weenie' MTBer or roadie riding an ultralight $10k+ bike while sporting an extra 30 -50 lbs of flab. It's a bit like me fishing a Loomis Assqueef.

Hope y'all are ready to buy the new bikes with 32" wheels!

Before I became a UPS package car driver I used to drive my mountain bike a lot. I still have that original mountain bike back in the early 1980s. A Schwinn Mesa Runner. I've been thinking of restoring it to a fishing bike. I still have the racks i added to the back for my days as a paperboy. I figured I'll just it to carry a pannier.

Those 80's Schwinn Mesa Runners MTBs are considered classic vintage rigid 'bombproof' steeds. I've a couple of pristine late 1980's Schwinn Cimarron's with handbuilt fillet brazed/butted frames and XT components....built just before Schwinn shit the bed in 1992.

For those of you who have infants or grandchildren getting ready to adventure onto two wheels, balance bikes ARE the way.

Our daughter just turned five and one of the gifts we bought for her was a new bike. We knew she was about ready for a pedal bike having ridden a balance bike for a few years, but had no idea she would take right off on it. Less than 5 minutes after assembling her new bike, she was off and pedaling on her own. She was so proud we went pedaling around the neighborhood shortly afterwards. We ran into a neighbor whose kid also got a new pedal bike and had the same experience with their kiddo.

New bike is a Prevelo Zulu Two and her previous was a Kids Ride Shotgun Dirt Hero. New bike has 16" wheels with hydraulic disc brakes front and rear with a single-speed freewheel rear wheel. Full face helmet has been purchased!

Super proud dad moment in the books.

I beat the crap out of mine. She's still running after all these years. I think I'll seriously tore her down and do a new paint on her and take all the parts and clean up/lube them (cables,shifters, etc)

There's a few folks on the GCN network that rightfully regard balance bikes for children as one of the truly great bicycling innovations.

Good on you! I've got a couple of scars on old MTBs that I'd never repaint because every one of them was honorably earned while riding....sort gives them 'street-cred' and brings back good memories, much the way old flyfishing gear does!

my worse..bombing down Montara mtn, a coastal hill just north of my old town of Half Moon Bay, had taken the same line dozens of times before, requires a lift launch over a narrow ravine bisecting the fire road...only this time on landing the stem on my early 80's Fisher MTB snaps...frozen moment as I go airborne head over heels still holding onto handlebars only connected to the bike by cables...over the side tumbling into a big thicket of poison oak...got home and wife said it looked like I had been attacked by a potato peeler...ended up with the worse case of poison oak imaginable, needed a steroid injection to slow it down

Reminds of the time are rope swing broke sending in into a forest of stinging nettles, in shorts and a half shirt, ah the 80s :ROFLMAO:

Luckily, the local creek was the best nettle relief and wasn't to far away!

You rode MTBs in the very birthplace of mountainbiking!

My worst crash didn't occur on a MTB, but rather on roadbike during a hard lean into a downhill curve with a patch of black ice hidden in the January shadows; woke up, feet still in the toe clips, blood streaming down the side of my face from a deep gash. Ended up with a concussion, stitches, and four broken ribs. Except for some scuffed bar tape the bike was untouched.

My worst mtb crash occurred attempting to bomb down a bit of highly technical basalt garden trail (that was clearly beyond my abilities) on a 1998 Diamondback Axis TR with those old elastomer Manitou forks. Did the full high-speed OTB and landed middle of the trail, earning some applause from some whitewater kayakers playing in the Spokane River adjacent to the trail (next to the Devil's Toenail rapids). They quickly paddled over to see if I was ok. My ego and body were badly bruised, and my bike suffered only a bent Bontrager handlebar, both of those shitty Bontrager rims destroyed beyond repair, and a deep gouge in the top tube that I cherish to this day.
 
my worse on a road bike was at Travis AFB. Late 60's, had gotten off shift loading air freight on C-141's, changed at the locker room into shorts and tank top, pulled out my 60's Bianchi 10 spd. The LT running our shift had a bathtub Porsche convertible and we'd both be heading for the north gate, him to go home to family and me for a back country spin...so we'd developed an informal first through the north gate wins...LT had to be careful pushing the base speed limit, I could take shortcuts...so spinning pretty flat out, go into a corner not knowing a road crew had spilled some bed gravel...slid for yards...off to the infirmary to get gravel picked out of my leg and arm.
Bikes are special because they give a kid the freedom to get out and explore at speed...same for big kids too
