Bike Maintenance for Beginners

I’ve just chopped the hoses on my gravel bike and routed them internally through some new bars. But the rest of the gravel bike is fully external. I’ve actually got a new stem, fully internally routed, and bars, sitting in my box of bike bits waiting to go on my Scott Addict road bike. I’ll certainly be watching for kinks now!!! I’m working up the courage to attempt the job. Shortening the hoses on my old gravel bike has been a practice run of sorts.

Tonight’s job on gravel bike is to bleed the brakes as shortening the hoses will have let in lots of air. It looks simples on YouTube but I’m still trepidatious.

Faff faff faff. It’s one step forward two steps back with this rebuild of my gravel bike (On One Pickenflick). Hoses are now routed through the bars and bled, which was easy. They needed it too as the Dot fluid looked discoloured. Rear mech recabled. Tyres and foam inserts installed and sealed successfully with Stans. And new mega cassette 9-46 11 speed installed. But my SRAM CX-1 long cage derailleur is too short (it’s max. 42 but it hoped to risk it). :sob:

So now I’m waiting on a Sunrace hanger extender. Even the new chain is sitting stripped and waiting to go on (hope it’s long enough). I may get onto the trails in another 2 weeks…

What’s cooking? A new 11 speed Connex chain, 500g of paraffin wax and 50g of PTFE powder. Cook on low for 3 hours then enjoy.

My gravel/CX bike is almost back on the groad. Just waiting on a front hub replacement.

So I’ve just got round to fitting my new di2 derailleur but I’m not 100% sure if it’s located correctly

Anyone fitted an R8050?

Does it go there or in between this two notches?

Can’t see anything online although I’ll have another search

In between or it’ll be able to rotate backwards on the nut.

Thank you

Just coming back to this if anyone does find themselves replacing their derailleur - it does actually fit as I had it in the above photo.

I moved it and bolted in between the two notches but the position of the derailleur didn’t look right when I started to adjust the b screw.

So actually took the the time to look for the Shimano fitting instructions and they show the installation as I have it.

In other news, I finally got round to replacing the creaky bb on the P3 - had to hammer the shit out of the old one then beat the crank back in but all looking ok now. Will give it a spin later.

Also took me two attempts to buy the correct tool online :upside_down_face:

Was that the Rotor one I put in? i do remember it being ‘snug’! :smile:

Yeah,

I ballsed up actually. I didn’t realise you could replace the bearing on that bb with having to replace the whole thing

So I bought a Wheels Manufacturing bb that does exactly the same :roll_eyes::grin:

Yeah f’ing BB tools. I empathise. Even Shimano have two tools now and the plastic adapter they bung in with new BBs is a POS.

Related- I bought a second hand Ti frame 10 years ago and to my surprise it came with a Phil Wood Ti square taper BB installed. Clearly the bloke couldn’t remove it. So yet another BB tool was needed to get it out.

If anyone wants to buy an expensive Phil Wood BB and tool then DM me :rofl:

I wonder who spannered Rui Costa’s bike? Watching the Tour Romandie prologue was certainly entertaining.

Was he running 1x? Did he lose his chain? I need to see this!

:rofl: :rofl: :rofl: Thanks for pointing this out. Suddenly I feel much more sanguine about putting my derailleur into my spokes a few weeks ago. I mean if pro mechanics fcuk up…

That happened to David Millar once in a Prologue TT IIRC?

some mechanic is going to get a roasting I reckon

I thought he tore the rim off his (shoddy) Mavic disc wheel? Might have been a different occasion: Millar's concentration blown with disc wheel | Cyclingnews

Different incident I’m thinking of. IIRC he dropped a chain as his team though getting rid of the FD would be more aero. This was in the days before 1x was a popular concept on the road.

Did I screw up? Was taking BB apart to clean and regrease and accidentally took out the cage leaving the balls loose inside the bearing.

Is there a way to fix it or do I need a need a new bearing and replace?

If it was me, I’d put the bike on it’s side rearrange the ball bearings evenly, whack a load of grease in there and push the cage back in.

Should be ok just to put the cage back in, was there no dust cover? I don’t think I’d pack with grease though as you would want something quite thin not to increase drag.

Fiddly but got it back in eventually. Think I’ve made it worse as it now feels rough. Might replace them.

Markings are 23477RS which seems easy to find. Have a bearing press but nothing to remove. Possibly chisel and hammer will work.
