First blind moment

I am faced with seat issues - not my rear but the seatpost itself. I had expected differing size seat posts, but I am left with two paths to functionality. Current seat post and a shim or a new post of 34.9cm. A larger area is better able to dissipate impact so new wins there. Current seat post is a little crappy and for safety I have already stolen the seatpost off my sons Hotrock 20" bike. So with an ex-stock EX seat post for £11 and a quick release seat clamp from Halfords I set about installing the seat post.

OK that was unexpected, despite both being the same size they are not, and we are not talking about layers of paint out of size here. The seat post clamp is clearly smaller than the post. With much effort and prizing the seatpost clamp open, it fits on snugly to the bike frame and the the seatpost itself slides snugly in with a fresh coat of grease.

My eye runs over the matt black frame and alights on a sudden flaw in my plan. I can see two cable guides on the top tube. One for the rear mech and one for the brake cable. Where can I run the third for the front mech? There is no room in the existing guides, so that will be a non-starter. To the batcave Robin! Several hours of internet research later and I find I have two options. Braze on series of guides - possible as there is a local bike builder round the corner from me (Renowned Chas Roberts)- but pricey as I would need to strip the frame, and respray again. Epoxy glue a guide to the frame - a sore point in forum threads on the subject. Buy a seatpost clamp that adds the guide to the bike (Problems Solvers). I look back for the post where in my early research I had read that a P3 had been converted to a 3x7 gear bike. Yes you can, but quite frankly it looks like a dog's dinner and uses the seatpost clamp. Given that the seller has been using it as a commute bike, I am not entirely sure that it will survive much of the hammering it will get from me. So we are going to have to go for a 1 x ? combination and walk up hill, no actual change there then as my current stamina level is still low.

So for a very simple parts exchange and upgrade model we are now beginning to look towards a total rebuild. The shopping list now requires

Bottom bracket
Single chainset with guide if possible

with the following upgrades
9speed hub
9 speed mech
brake arms
new forks if possible to return the freebies back to the pool.
