Re: Doing my own maintenance

My first port of call when I'm stuck is usually Sheldon Brown:

Re: stripped threads in frame /bottom bracket .is this termi

I haven't used one of these, so can't comment on the quality, but the blurb claims that they're better quality than YST:

Re: Chain wear

your chain is steel, and at least the smaller sprockets will usually be steel too. Your chainrings and the larger sprockets are likely to be alloy. If you allow the chain to wear too much before replacing it you will wear your chainrings and casssette also, meaning expensive drivetrain replacement. ...

Re: Chain - "quick" link

here's a wee bit on SRAM powerlinks by Jobst Brandt which may shed some light and make things a bit easier:

Re: Splitting powerlink, lubricating rear mech, dirty hands,

I seem to remember posting this on another related thread, but an alternative to the (bloody expensive) Park pliers are:

Re: Do aluminium frames 'go off'

sorry, I meant to post this link for some further reading on the subject. It is a bit dated, but as far as I'm aware the science behind it hasn't yet been superseded:

Re: Do aluminium frames 'go off'

aluminium has no endurance limit, unlike steel or titanium, in that even a very small load applied repeatedly will eventually cause fatigue failure. The key consideration will be in the design of the tubes and frame. There are quite a few old aluminium frames around though, which suggests that eithe...

Re: OLD SHOUGON SHOLD I SINGLESPEED IT

If it's got horizontal drop outs then you should definitely convert it to fixed gear in my humble opinion. Takes a bit of getting used to, but after a few miles you will start to wonder why you thought you needed gears or a freewheel in the first place. Then when you get back on your geared bike you...

Re: Ideas for a 200 mile round trip from Edinburgh

I cycled Route 7 from Glasgow to Pitlochry around this time last year, carrying camping gear in panniers and on my 700c wheel tourer shod with 32mm tyres. I would submit that 28mm tyres would be fine, particularly if it's dry, but would avoid carrying so much as I did. The route up Glen Ogle from Ca...

Re: New to fixed wheel any tips?

Hi Ash28, congratulations on taking the decision to go fixed, you'll wonder why you persevered with ss so long! Make sure you've got the right gear for you, not too low that you can't keep up with the pedals the first time you hit a downgrade, and not too high you can't plug up most hills. Keep your...

Re: What type of bike? Another newbie request for help!

I'd keep an eye on the for sale forum on here, if you're prepared to do a bit of research and wait for the right bike to appear there are some great bargains to be had. Also, given that it's mostly bikes which have been owned by venerable CTC members, it's likely that they've been better looked afte...

Re: KMC chain splitting

I got a pair of these: http://www.charliethebikemonger.com/qui ... -290-p.asp - considerably cheaper than the Park pliers, and I really can't see where the extra money goes, unless you really need that 'Park' logo!
