Difference in frame weight between good and bad
 

Hey so I got this bike for £20. What do people think the difference between this frame and say carbolite 103 is?

My last bike was carbolite 103 and I got this as it was the correct size. I can take the components off my carbolite which includes alloy wheels and other components.

I have to build this thing up either way, should I bother going for alloy bottom bearing and chainsets? Also planning to go for single speed as saves me having to buy derailers and I can save weight taking the cogs off the back.

Am I looking at say 1kg between bad frame material (this probably) and medium quality (carbolite 103)

Well, I would say that the difference between a good frame and a bad frame is at least 1 henweigh.......

Well, I would say 6 or half a dozen give or take.

I have quite a few frames in the same size range, built with Reynolds, Vitus and Columbus double-butted tubesets. I also have a "lesser" frame constructed with seamed tubing. It is not poorly constructed, by any means. While it's not pretentious, it's clear that whoever constructed it used care; that's what appeals to me about it, and makes it one of my favorites. It weighs as much as 600 g more than my lightest frames of the same size; but only 400 g more than a Peugeot PX10, or a Serotta Club Special.

So, not that much difference in weight. There might be more difference in ride quality; and I grant that the the lighter frames provide a livelier ride. But I've decided that this isn't everything in a frame, for me, when all is considered.

Concur. Lighter is nicer, but I find geometry and fit (determined by top tube length and seat tube length) to be more important than frame weight. My lowly Peugeot UO-8 is surprisingly fun to ride.
