Learnt something new today.....

[funnymummy]

Had to do a few tweaks to #3's bike last week, which included a new rear mech.
I volunteer at a local Bike Project & while i'm good a basic mantainance, i'm no expert & am learning new stuff everyday.
So back to the rear mech, James (another volunteer) fitted it for me, but no matter how hard we tried, fettled, tweaked & twiddled we couldn't get the gearing right, 1,2,3,4,6,7... where did 5 go? It would just skip from 4 to 6.
On another thread it was alked about 7/8/9 speed derailleurs.. & Mickle explained the differnce to me. Thnak you Mickle X
I wondered if this could be the cause of the prob, wrong size mech.
So today Adam (our chief guru on all things bike looked at it)
Apparantly we'd used a 1.1 mech on it & it needed a 1.25... James & I both did the face!
So, we had a lesson in SRAM shifter.... now I know all about actuation ratios too...

What did you learn today....???

EDIT
Didn't know this pic had been taken until it just appeared on our Facebook page..That's James & I looking very confused, while Alison looks on even more confused!

too much digging and lifting makes one back ache and twinge

how bloody easy it is to replace the bathroom tap innards, one went very very stiff

£12 and five minutes to fit brand new valve inserts and taps, easiest win ever

Today I found that Butter does not remove grease stains from my Paramo rain smock and I'm not a happy bunny.

If drivers look straight ahead when waiting to pull out of a side road, or onto a roundabout, they cannot see you approaching them, and you therefore officially are not there. Or should not be. And most definitely do not have right of way either. Na !
