3 Rapid-Fire Mountain Bike Tuneups

We need a compilation of Seth distributing sealant by wildly bouncing the wheel around

As someone who rode a Trek Marlin 8 for two years and broke the front and rear axles at least once each, I can tell exactly how it happens: riding it like a trail bike. Marlins are cross country bikes and are not intended for chunky technical trails, and certainly not big drops and jumps. I'm riding a Roscoe 9 now with much beefier thru axles, and I couldn't be happier.

Rapid fire cmon I want an hour long video

I’d love to see a video where you get the kids you gave the bikes to along to service them and teach them how to look after their bikes!

I had this same problem with computer hardware. After fixing someone's computer or even giving them one, you become the owner of all their problems.

Your bike repair videos are among the best content on the entire Internet. You're a fantastic educator!

I always put a differently-colored spoke nipple in when I replace spokes on my own bike. Lets me see exactly how many I've had to replace 😅

" This time these bikes are leaving my house for good. " FAMOUS LAST WORDS. 🤣🤣

I recently became a bike mechanic at a local non-profit bike shop, I had no formal schooling in bike repair and my education on the subject is almost entirely made up of what I've learned watching all your videos for the past several years. Thank you so much for everything I've learned from you Seth!

The Marlin 4 can be swapped from a freewheel to a cassette (I converted mine from a 3×7 to a 1×9), but for most people, doing that isn't worth the effort considering how you'd have to do a full drive train and brake swap in the process (the stock shifters and brakes are integrated into each other) and you'd need a new rear wheel. I did it with mine to see if it was possible and bike rides great

Straight as a bent arrow

YT is your best friend when it comes to learning how to repair and maintain your bike. I firmly believe a person shouldn't own a bike unless they know some basic maintenance. I don't attest to know how to do everything but I would say I can repair and maintain 95% of the problems on a bike and the place I learned to do that stuff is through years of watching YT videos. I'm sure plenty of people disagree with me, but those people are probably the ones who don't know how to repair and maintain their bikes. I work at a retail store and assemble bikes and a couple months ago we had someone return a bike because they got a flat tire. If you can't fix a flat tire then I'm sorry, you shouldn't be riding/owning a bike.

I actually replaced a freewheel for a freehub on my bike (the axle was bent and I didn't feel confident replacing it). Not that hard in the end (spent about 5 hours). Just needed a new hub & spokes. I feel really good about this upgrade with the new cassette

I enjoy the repair videos. Broken axles are pretty common on freewheel hubs since the hub body is so narrow, leaving a lot of axle sticking out the drive side. If it breaks again a cassette hub would be a nice upgrade I think.

I love all of the Berm channels, Seth. I'm gonna be doing my first big ride in a very long time in Chequamegon-Nicolet National Forest in Wisconsin all because this channel inspired me to do it.

See this is the problem giving out bikes, you become the free repair man :P

axles break like that because old freewheel style hub, plus kid, likely riding hard and jumping. this is why when shimano brought out the parallax cassette hub it was such a game changer. moving the drive side bearing out to near the rear mech, and bearing riding on a steel bolted to the hub casstete body made the wheel much stronger, a designed they've only just gone away from with the microspline rear hubs which moved the drive side bearing back to the hub body

Teach the kids how to do this, these are such simple fixes. Great videos though, love Berm Peak

here's a hug :virtualhug: for being nice to those boys all the way

I remember once when I bent my seatpost on my BMX bike my dad took a metal rod and pounded it into the seatpost tube to the right height and I put my seat back on. This was about 1990 or so. We also used a crescent wrench as a spoke tool.😊
