So I've seen a few custom shoppers and it got me thinking how I would go about one. I managed to find this BSA 20 pretty cheap so jumped at the chance.

I didn;t realise how heavy they were! 18KG for this in a stndard form is a huge weight, especially when you consider my 29er full sus weighs less! The first part of the plan is to get this thing on a diet! Replace as many of the steel parts with alloy to shift the grams (or kilos!). I'll be converting to 20" BMX wheels at the same time so I'll build myself a fresh set with alloy rims to lose more weight.

The second part of the plan is to tackle the gearing. My first though is a belt drive system. It's something that's intrigued me for a while but if that falls through, I'll be potentially be adding a derailleur. Maybe.... This might actually suit just hub gears.

Before I do all that though I need to tackle that crankset and the 77mm bottom bracket and prey it isn't Raleigh threading!
