I have Shimano GRX groupset and the rear shifting has been pretty erratic lately. Got a new chain and cassette, replaced cables and housing, cleaned and lubricated everything, and it's still not working great.

I wonder if something is broken/worn inside the shifting/brake lever (ST-RX600). Does that ever happen (after 10 000 km)?

I am an experienced home-mechanic but never took a drop bar shifting lever apart, judging by the looks it's a bit scary.

Just putting together the bike now after the SF trip

I guess I let too much air out packing it. Tire got unseated... Tubeless setup is a big mess

Sealant flying everywhere when I was testing the rear derailleur after putting everything together lol

I couldn't get the tire bead seated properly no matter how fast I pump the floor pump I have. The electric pump was also no help. Eventually I used a CO2 canister which got the job done! I just need to remember to pump the tire with air next time.

A note on a broken front bike wheel (ENVE SES 4.5)

I was going to take the Pinarello out today, but I noticed one of the spokes on the front wheel had come off the hub...the picture shows the spoke resting on the broken part, but it can move freely... It looks like the part that keeping the spoke in place on the hub had somehow broken off, which is very weird because I hadn't ridden this bike for 4 months, and last time it was fine.

I submitted a warranty claim to ENVE which has lifetime warranty for wheelsets. They responded very quickly and asked for pictures of serial numbers. But man tubeless setup is sooooo annoying. It took so much effort to take the tire off because everything has to be airtight. With sealant splashing everywhere and slippery it hurt my fingers trying to push the tire rim off 🥹

I had to do this because the serial number is under the rim tape (again, required for tubeless setup). It was a pain to take off the rim tape too!

But glad that ENVE warranty is so good!

Well back in late November of 2025 I had to make the hard decision of getting rid of my little Fiat 500 and look for another car as the Fiat needed a CV Axle, which was very difficult to find. I absolutely needed a car as fast as possible and settled for a 2012 Toyota Yaris. Fast forward a few months and although the car has been pretty reliable it suffers from some neglect and needs some TLC. The exhaust gasket after the exhaust manifold leaks, a common problem. I ordered the gasket and installed it about a week ago, only to realize it wasn't the right gasket. Ordered the correct genuine one, something I should have done in the first place and waiting for it. As of this morning the dashboard lit up like a Christmas tree with the ABS, Traction Control, brake icons, most likely a bad ABS sensor of wire harness, still to be determined. I don't want to give up on this car. Wish me luck #diy #car #automotivediy #homemechanic #homegarage #toyota

So I ordered two more tools:

Tire Glider (the red, small thing)
Kool Stop Tire Bead Jack (the big black thing)

Tire Glider claims to make installing tires tireless and my friend confirmed it worked well for him. Another friend told me it didn't work for him because it simply didn't glide on the rim because the tire was just too tight. And it was exactly what happened lol maybe spraying so.e soapy water on the rim and tire bead would help...

But the bead Jack totally worked. When the tire bead is that tight, all that matters is leverage! (Or if you have iron thumbs and arms)... This thing worked like a charm. It is bigger (so only useful at home) so there's way more leverage.

I've since reindexed the rear and front derailleurs. Shifting is back to normal. I've noticed other issues though.

The front and rear wheels are no longer true and have some pretty visible deviation. They can only spin freely if the rim brake quick release is open. The rear wheel is also making some kind of rubbing sound, as if rubbing against the brakes, but as far as I can visually tell, they it isn't.

The chain also sometimes rubs against the front derailleur in a certain gear and when under load. There is no creaking sound, so I don't think it's the bottom bracket. Some say it's frame flex. My bike is aluminium. I don't know how flexy that is.

The rear rim brake calliper is also gunged up and does not return to its original position after closing. It looks pretty dirty though. But since the calliper is from Tektro, I decided to spend 20 bucks to get a Shimano 105 calliper. The tektro one can then be used for learning purposes!

So here are a few things I tried:

1. Thread the pedal in from the other side. The pedal went in halfway before it got stuck and I think I damaged more threads removing the pedal now.

2. Bought a set of socket wrenches (since I didn't know all I needed was a 15mm one) and tried to take off the crankarm. If I could take it off, I could order a replacement crankarm. Why would you buy a new crankarm if you couldn't replace it, right? Well, the socket wrench set, the second cheapest on Amazon, sucked ass. They were made of soft metal and the 15mm size was more like 15.2mm. The wrench rounded out after a few tries...

3. Took it to the LBS. The shop owner said he won't fix it because he didn't want to take responsibility of what happened to the bike. Told us to return and refund the bike instead. My partner loves the bike, so no can do.

4. I bought what looked like a decent crank removal tool. I could tell it was better because it was heavier, so properly denser, harder metal. Plus, it came with it's own wrench, which socketed in on all 6 sides of the hex-shaped tool. This did the trick, since I now had enough grip, leverage and stability to undo that crankarm nut and remove the crankarm. It wasn't easy though and took me 15 minutes of wrenching with all the strength I could muster whilst half-kneeling.

tldr: I removed the left crankarm of my partner's city bike.

Gave my new-to-me 90s winter bike (see https://mastodon.social/@nikcorg/111324944622045466) some TLC and killed my Park Tools pedal spanner in the process. Thankfully everything else opened up nicely and didn't appear too neglected. Still miffed about the pedals not budging.

Also, who the hell thought cantilever brakes were a good idea? Absolute pain to adjust.

What an absolute bitch of a job this turned out to be. An hour (normally) or so's task made into a couple of days; applying release spray a couple of times per day and much straining at a breaking bar lol. I'd decided to DIY after losing trust in my local mechanic who emphatically told me Mazda 2 rear struts + mounts aren't the same as Fiesta Mk6, they're a dealer part only...2 weeks wait! They're marked 'FoMoCo' FFS. #Mazda2 #HomeMechanic

Today I've spent the whole morning trying to find Goodyear 215/60R14 tires. I have two with good tread though they're quite old.
Finally had to resort to calling Goodyear corp number.
Wating for a callback from the nice rep who is checking for me.
As a last resort I'll have to buy 4 of a different brand. BFGoodrich still makes them.

Attached: 1 image I can't find my own old toots when I try. Another thing to figure out. ☹ Anyway my buddy came over and I'm another step closer to finishing the 68 Cougar project I started in 2016. Been a long road.
