What was the last bike you worked on?

[@WorkLessRideMore]

My own bike. Got to a trailhead at a higher elevation and the brakes needed a lever bleed. Good thing they are shimano because it was super easy to do in the parking area.

[@dawg7750]

My Roscoe 7. Spoke was loose on the trail so I used my tool to tighten up!

[@markopavsek3189]

Wife’s Orbea Rise. Wanted to change rear break for a stronger one but the new and the old hose that were combined together with Sram tool disengaged while I was pulling / pushing them through the frame… so the new hose got stuck in the frame and due to battery position couldn’t push it out. Needed to take the bike to service where they uninastalled the motor and the battery and pulled the hose out, then reassembled it back together. I did install and bled the brakes by myself. 😎

One of the many things I like about mountain biking is working on my own bike. Recently I installed a dropper post and installed new derailleur cable. Future maintenance will be done by me, when needed.

Great show with Calvin and Truman! Been working more on friend's bikes this year to expand my knowledge. Getting good input from bike owners is so important towards addressing their bike issues...and subsequent repairs.

[@Milessongs]

Absolutely brilliant! Thanks for bringing 4 of the most prolific bike mechanics online together for this discussion! 😊 p.s. Calvin Jones is a national treasure.

[@danielcobb8886]

Missus and I loved this episode. Will keep the wise words stored. A big thank you to all involved! Looking back to a few days ago I realize that upon finding the replacement thermostat for my car was 2mm too large in diameter I was not at all prepared to fail. Quite a lot of time, careful filing, test fitting and swearing later I made it work.

[@RobThePatentGuy]

Thanks for a great video! I've been working on my own bikes for over 3 decades and enjoy the process and rewards.

[@playgroundchooser]

Calvin! One of the people that taught me that I can do about anything to my bike myself.

[@ericfroehlich976]

When I started dating my gf i could tell her two kids were scared to break things or toys. It was a symptom of their early childhood with their father. I was conscious of this and adamant in telling them "just break it so we can have fun fixing it". Getting to teach them and learn with how things work has been one of the biggest joys of my life. Kids need to know that it's ok to break something or fail in trying to fix it. We all become better for it

[@seano218]

Keep your kids away from other people's things!

[@LebronPhoto1]

I tend to work on old bikes on occasion. The biggest issue I have run into has been related to removing stuck, old square tapered bottom brackets. I learned that it's important to have the right tools. Every time I have run into this, my first step has been to obtain the proper tool so that I am not repeating this error again. That said, people learn (usually) by doing things and either succeeding or failing. I find that the failures provide the most valuable lessons. I had to laugh during the torque wrench discussion. Back in the 70's when I was a broke teen and didn't have a torque wrench, I broke or stripped many bolts by over tightening them.

[@grummbeerbauer3527]

"Fixing a bike is rewarding" - can't agree more on this. Being a desk warrior by profession like probably many here, I often have days where I am busy 120%, but at the end of the day, I really don't see any tangible outcome. That is why I generally enjoy most bike repairs, in particular since I now have two bikes, so I don't have to fix things "by any means" anymore as I want to get out to ride, but can do it when I am in the mood and have the time and patience.

[@robertmcfadyen9156]

Remember "SHELDON BROWN" .

[@OwenBikeNerd]

Agreed - another legend.

[@fpeter01]

My fail list is pretty long: slipped bike in bike stand -> broken derailleur hanger, shortening cables without pulling the inner cable back, putting on the bottle cage backwards, dot syringe jumped down -> dot fluid went everywhere, hammering out a brand new BB, because I forgot the spacers, screwed rotor bolt head... Thankfully most fails were not expensive, but still they were time consuming. An unsuccesful bleeding cost you about half an hour... But being your own mechanic is kinda cool. And if you have 10 bikes, it is really cost effective.

[@bchearne]

16:33 wearing headphones isn’t just bad for your bike assessment opportunities, it’s also a little dangerous. Situational awareness is a thing

[@JosephSAi2HT]

Mantra i’ve stuck to for some years, i reckon many would agree is: 3 people you dont want to piss off, but duly take care of - dentist, barber, and your MECHANIC! (Especially Anna, 😜 jus sayin’, bloody amazing she is! Yes Owen your just as gr8 M8!) For the kiddies, if you want experience to duly take care these important people in your life, throw in your parents, lol!

[@Cycle9568]

[@vinny61389]

Breaking things as a kid is so helpful to building a lifelong curiosity and comfort with occasionally breaking things you try to fix (hopefully less as time goes on).

Seem to be tha story of my life, cleaning up someone else's mess..but it does have a feeling of satisfaction after all is said and done...dealing with automotive electrical and mechanical cluster fuks at times...then being baffled by a bicycle makes you rethink what do I actually know...😂

[@prolfinator]

Parktool needs to invite gmbn to cuyuna/ north shore. May not have the most vert but it's still fun lol.

[@seraphan6]

Working on someone else's bike is often more fun because your emotional connection to the experience is very different. As the mechanic (not owner), you can focus on solving problems and not worry so much about riding time lost or how much the repair costs. As the owner repairing (or building) your own bike, the experience is a blend of frustration and satisfaction.

[@Brendan95902]

The whole issue of sounds that one's bike makes could be the topic for a whole episode! What the different sounds could be and which ones need urgent attention? Sometimes the LBS seems to have real difficulty in hearing what the rider hears, or understanding what the rider is saying and being able to effect a repair. My bike has been back twice already since a major service for a clicking sound that seems yo be coming from the bottom bracket (a dub with GX crank) that only seems to start happening after 6km or so on a trail. They just can't replicate that in or near the workshop, but as a semi OCD person it is driving me to distraction and ai am allowing it to ruin my rides! They will be getting an instruction to replace my BB just to rule that out. Maybe foam ear plugs could be an answer?😊

[@hellkitty6663]

I'm quite new to cycling and still learning the basics. My last fail was not checking the chain wear often enough and in the meantime I rode my bike more than I thought. Well, now I don't only need a new chain but also new casstte sprocket 🥴 but what I find infuriating is, that if I have a bigger problem which I can't solve or I would need quite special tools, than I have to wait a half year for a workshop appointment because they are so busy doing the general maintenance stuff for people who are too lazy to learn to do it by themselves

[@Emtbtoday]

There is three of us in the family and twelve, yes 12, bikes. Home maintenance is a financial must do for all but the most difficult jobs. I look forward to passing down years of accrued knowledge to my lad to give him the means to have a happy cycling life.

my problem is, I stop before the wrench clicks, because it seems way too tight. and that's with a new or newly recalibrated wrench.

[@bchearne]

I have the opposite problem when I work on carbon or aluminum stuff, and I’ve had to use thread locker more often to keep things in place since I got a non-steel bike. Recommended torques can be really low when you’re threading into softer materials

[@jakebrakebill]

@@bchearne I often compare my natural feel to the torque wrench and I'm either right on or slightly under. Things I don't trust staying tight or won't be taking off for a while get the good old Loctite.

Great question! We'll try and tackle this with Calvin! Cheers Owen

[@TitoJoebs]

#gmbntech Hi guys! I'd like to know which is more efficient to use: Spider mount chain rings or direct mount chain rings? My son & me are betting that this one is better than that one. I told him that however if he losses one tiny bolt for the direct mount, the chain ring will start to wobble & "game over". Unlike, spider chain rings, when you loose one bolt, at least you still have 3 more secure bolts, right? What would be your personal choice? #owenbikenerd, #payner25, #zimblake, #neildonoghue, #annaonthebike

[@hughjanus7354]

Before I watch till the end, are you going to deep-dive by doubling down on available market synergies through gamification of shareholders value in the ever changing landscape of corporate restructuring? PS the word you're looking for is "analyse", not "deep-dive" (unless this is a channel for PADI certified scuba divers or frustrated financial analysts) . PPS I love how you introduced them (your sponsor) as Park Tool*s* when they are Park Tool - you'd even spelt incorrectly in their lower thirds. The deep dive now makes more sense... Hollllllllly fffffffffffffk.
