bought this frame about 3 years ago off ebay for £20.from the serial no. it i.d's as an rl 240.but is very much the same as an rl20b.it has a slight crack in the seat tube (hence the doubled up clamps) most of the other bits are stuff i've had for ages kicking about,aswell as a couple of recent buys from here.but i reckon its cost me about £170 all in. i quite like it and it rides pretty smooth too.gonna give it a blast at the boardroom meet next saturtday
