the 'there's no such thing as a stupid question' bike maintenance thread

magicbastarder

is there a simple list of chemicals which you should not get near disc brake pads? i.e. would even something like a detergent cause issues with contamination; i was wondering as i was cleaning the bike earlier if i can be overcautious in cleaning the bike near the brakes.

any tips on looking after a steel frame? my latest purchase has mountings for racks and also a couple of unthreaded holes - should i tape those up to keep water out, or leave them uncovered to let the water out should it get in?

Technically, that chainring is a bit worn, and so will wear a new chain a little faster than a brand new chainring would but, given the price of a new chainring versus the cost of a new chain and cassette, I'd run a new chain and cassette on this 'ring one more time, and then when that chain and cassette are worn out again, I'd get all three and start again fresh.

If it makes any difference price wise it’s a 105 chain set. New cassette is ultegra as 105 doesn’t come on 12-30 and chain is kmc xl10s

Anyone?

Hard to say - wheels are like car insurance - the deal that someone else got may not suit you or vice-versa. Note that the Cosmic front wheel is a clincher and the Zipps are tubulars - have you thought about which you would prefer?

Put new wheels on and while transferring cassette I did a deep clean. Now chain started slipping on some gears. I think the dirt had actually been stopping it from slipping.

Measured chain and it’s a bit stretched but decided it’s time for new chain and cassette, no worries

Got them today and while I have the chain off looking at the chain ring does it need changing too?

Looking at a new wheel set and really dont know much about different wheels to make a decision!

https://www.donedeal.ie/bicycles-for-sale/zipp-404-carbon-wheels/20675352 <- Older Zipp

https://www.donedeal.ie/bicycles-for-sale/mavic-cosmic-carbone-slr-front-wheel-clincher/20685584 <- Cosmic SLR

This would be using for TT. Ideally just looking at fronts only, but would a better wheel be the older Zipp or something like that Cosmic? Or is it much of a muchness?

Anyone?

Quick question. I'm building up a commuter with old spares. Will a 50 36 chainrings work with an 11 28 or 12 27 cassette with a short cage derailleur. It's a 10 speed mish mash of 105, ultegra and tiagra. Thanks in advance.

I don't see why not considering my 2013 Giant Defy came with Ultegra 50/34 chainrings, an 11/28 cassette and a short cage rear derailleur.

I imagine some one here can give you a proper yes or no though.

I wouldn't have used any detergent if using the washer, just put it on a hot wash and let the mechanical action and heat take it away.

I bought a new 250 quid bog standard road bike for my 20k round trip commute 3 months ago, what would be the typical timeline for maintenance/servicing etc.
I ask as all guides I can find online are geared to the more enthusiastic cyclist with expensive bikes (i.e. wash drivetrain after each use). I've washed & oiled the chain about once every 500km. Other than that, should servicing be annual? I was thinking of doing it when summer starts after the worst of the weather has ended.

the salt will be a big limiting factor - but cassette and chainrings, anyway? jockey wheels too?

Why is everyone so stressed about salt? It's used in low amounts as a rinse aid, the residue shouldn't be visible to the naked eye (9mg/M3).

Dishwasher detergent is very caustic, so avoid putting anything aluminium in there.

In my early teens (1985), I stripped the axles and freewheel off a pair of yellow-but-filthy Skyway Tuff II BMX wheels and put them in the dishwasher when my mum was out. Got them out before she came home, and she never knew.
The wheels looked amazing, but were just as dirty a few months later...

To be fair, we only got one because we'd moved to a new house a few years earlier, and there was a plumbed space for one in the kitchen - my parents spent a year or so looking at the hole, whilst saving up to fill it - if the house hadn't got the plumbed space, I doubt we would have got one until much later.

Bottle of coke and a brush might have been quicker.

The coke was for the bricks, not for energy to scrub the bricks, just to be clear.

Paraffin oil and a match burns away the stain also...

To be fair they were stripped to nothing and had been cleaned, the dishwasher gave them an extra clean, the only fluid in the would have been residue on the piston or in the piston housing. I was prepping them for paint and rebuild

I’ve put most of a group set in a dishwasher before - minus the bottom bracket - and everything came out sparkly and clean. No issues at all. Made sure it was dry and lined after.
Also put a pair of shoes in there one time too.

I've put cassette, crank, chainrings all in the dishwasher. A rinse and a spray of something like WD40 is essential after though. I'd have no problem sticking brake calipers in either, once they get lubed after
