Last night a problem solving session resulted in a further fettle. Annoyed with myself on this one.
Replaced middle chainring on Sunday (on the Sunday) and didn't have time for a full road test.
<snip>
Doh ! New ring is 42t whereas old one was 40t.
Had to raise the mech up the seat tube a tads to get it all working, but the mech is now quite a bit higher in comparison to the big ring than all the books recommend.
Should I be worried ?
I'm kind of mystified as to why that should be. Is your chainset 30 inner, 50 outer? If it is that would imply that the biggest gap that can be accommodated on the front mech is a step of 10 with a max overall capacity of 20. Hence 28/38/48 would work as would 30/40/50 and 32/42/52 but your (I'm guessing) 30/42/50 is too big a step in the middle.
Doubtless there'll be a real tech head along shortly to tell me I'm talking bollocks <Grumpy on> It's what usually happens <Grumpy off>
Meanwhile: Last night (Tuesday) a friend of the eldest appears at the door and asks Mrs Torslanda, she of the horned helmet and heavy metal breastplate, 'Is your husband in' (The kid's 11!) It turns out he has a
decrepit heap BMX in need of a fettle, The chain is broke, there's a flat tyre, it's got no brakes - all the usual stuff.
Polite kids being rare around here (Kin'ell! You should here the way they treat the staff in the local takeaways!) he'd asked so politely I just couldn't say no. Break out the tools. Lose a link, mend a puncture - and like that!
Tonight (Wednesday) he's back. With a lever (broke) and a brake cable. He'd fed it thru the eyelets, bless him, but it still had both its nipples. I thought 'I can't let him ride this' and gentle questioning told me he had BOTH brakes. I pulled a junker off the heap at the bottom of the garden and set to work. An hour later and he owns a working BMX with TWO -
count 'em! - brakes, a grip on either side of the bars -
Luxury! and the puncture fettled properly. And I've cannibalised a junker so it's cost me precisely bugger all!
A short while later he's back. his mum wants to know what wine we like! I think I'm going to have to start charging people . . .
