I think our DTB is having his hair done on those two days, it's unfortunate, but there you are.

Not true!

I'm getting my nails done on the second day.....

Parcelforce has delivered a gert big box - Santa would never have got it down the chimney!

Some minor assembly to do in the morning and then adjustment to suit my riding position - pictures soon.

It's a good job I had this book for Christmas;

It's the thought that counts
Hope you've managed a quick test by now.
Meanwhile, big news. Back home and feeling righteous.
! hour 14 min 30 sec at 143bpm. Usual route. Felt quite good considering I haven't been on the bike for a month, and the amount we drank last night !

No ride on the new bike yet; in fact no ride on any bike since last Friday! This morning I just unpacked it and reassembled the handlebars to the stem before we headed off for a walk and some fresh air. I'll fit the pedals later so I can start setting it up after work this week.

Having dipped into the Chris Hoy book I have to say I'm rather pleased I received it as it has a lot of good information. There's a whole section on setting up your bike with lots of good explanations so I'll reference the section to see how it works out compared with how I've always done it!

I don't recall ever having done this job before.....
I unpacked and assembled the boys new team mx-24 yesterday....
I didn't read any of the instructions...smart arse with memories of the 1960s having built all my bikes from scratch with parts from various doners...

well...when it came to the pedals...they are marked R and L so I followed the R and L being the correct sides when sat astride the bike...so R is the chain side and L the non chain side......but thats counter intuitive because following this logic the threads are set so that the pedal will unwind and fall off when riding normally.......

is this correct??....I then read the instructions and it seems that this is correct.....so I tightened them on as hard as I could......

[Dave the bass]

Aha, the right pedal has a normal thread, but the left pedal has a left (reverse) thread.

The reason for this is not obvious: The force from bearing friction would, in fact, tend to unscrew pedals threaded in this manner. It is not the bearing friction that makes pedals unscrew themselves, but a phenomenon called "precession".

I wish I wrote that but I didn't, its copy and pasted from -> https://www.sheldonbrown.com/pedals.html

I was going to tackle that subject too, but I was in the bath after my bike ride

ps. actually there was a known problem years ago ( do Ed or Ray remember this ? ) that French frames had the opposite direction threads in the bottom-brackets to Engish and Italian frames - and they were notorious for the 'fixed' cup unscrewing.

For a new bike, I was going to get myself measured up at somewhere like cyclefit and then go to wiggle...

...or is there a better approach...
