Avoid sealant explosions by fitting the tyre first, pumping it to set the bead then just fill through the valve. It's a lot cleaner and offers a chance to check the tyre is good before things move to the messy bit. A few years ago there was an issue with some Maxxis TR tyres being slightly wonky, most people didn't find out until after they were full of sealant and getting a refund was made awkward by some vendors as a result. (Note: these issues seem to have been due to early production, Maxxis haven't displayed this issue since to my knowledge).

Great ones Niel! The backwards tire has happened more than I can admit :) Another wheel issue, maybe not that common, but if somebody comes in with a broken spoke, it's very possible that other spokes are about to explode... so if the customer only wants to change the broken spoke instead of all spokes, be sure to true & stress the wheel BEFORE putting cassete, strip, sealant and tire back on. I've had a spoke nipple break on the test ride, and have to take everything off again :( Another minor one is changing cables without screwing in the barrell adjuster. It's frustrating when you just need a few clicks to get the shifting right and find out the adjuster is already all the way out!

Tyres on wrong way round, forks on wrong way round after I serviced the lowers, removed a internally routed gear cable which didn't have the full outer sleeve running through the frame 😞. Think that's everything. The thing about making mistakes, apart from the fact that it shows your human, is that you always remember next time.

Steel frame with an aluminium seat post causes galvanic corrosion which is when moisture gets between the two it actually creates a basic battery. The aluminium gets transferred to the steel to create the voltage (very low voltage) and they literally weld themselves together. So if you don't grease the seatpost then you may have to end up getting a new frame.

I have an aluminum dropper seat post, which stopped working, cold welded inside a carbon mtb frame. It's impossible to remove and no bike shop will touch it for fear of damaging the frame. I've been able to secure it in place so its no longer a dropper post, which sucks, but the bike is still rideable. I now make it a regular habit to remove and grease appropriately my seat posts.

I still run a tyre deliberately on backward.... I run Maxxis DHF's so mount the old front on the rear backward... relying on the design of the front to only have load in one direction (Under braking) I mount it on the back backwards to have the strength in drive (I'm not worried about braking in the back, its either sliding or locked near airborne... and light breaking for corners doesn't matter).

Greasing the seat post is a mistake I made once. I was wondering why my seat felt a bit low after a few weeks, and realised that the post had been wiggled in by several centimetres! Tightening the clamp didn’t help, post was still sinking into the frame over time. So I completely degreased the seat post and the inside of the seat tube, put some assembly compound on, and that stopped the seat post from working its way in.

I actually had a shock canister fly out of my hand can damage the seals. I did in fact let the air out of it bat the valve stem but I didn't cycle the shock so there was still a little error ahead of the packing. Luckily it only hurt seals on the bottom of the canister but I was installing a volume spacer and it was a brand new shock.

my mistake was buying a used bike with a shitty front brake twice. Both times the pads were completely ruined cause of oil. Almost replaced the pads before i found out it was leaking at the caliper... And you only find out that the threads on the fork are shit when your trying to install new brakes.. And you can ruin brakes by forcing the cilinders in the caliper back..apparently you have to open the bleed valve before doing so.

That’s why tyres are already designed in a way to give you more traction when braking (take a look which side of the centre knobs is the sharp side), so by mounting it backwards you actually reduce braking traction.

If all else fails, take off the crank, disassemble the pedal (if its seized on it probably needs a rebuild anyway...), clamp pedal spindle in a vice and use the crankarm as a lever to unscrew the pedal spindle. This will work and save you from having to use clumsy tools on the annoying little flats some pedals have, or worse, round out the hex socket.

Another easy way to loosen stubborn pedals is to point the crank straight down, insert the hex wrench so it's pointed towards the front of your bike, stand on the pedal, and then use your arm and body strength to pull the wrench towards you. Unless the pedal is welded on, it's guaranteed to come loose.
