In another thread Richard Goodman said that new bikes were supposed to be faster than old bikes. This lead me to thinking 'are new bikes any lighter than the equivalent of, say, twenty years ago?'. Newer bikes have more gears, heavier combined levers and probably some other 'improvements' that don't come to mind right now. Reynolds 531 was introduced years ago and is still in use. So, does anyone have a direct comparison they can offer? (This may be more appropriate over in .tech but they are a bit trigger happy with their flamethrowers and I don't have my asbestos bibtights on today!) |

Whether they are faster or not is a different thing.Eddy Merckx would have probably beat everyone even if his bike weighed 5 lb more than everyone elses in a race, so losing 5 lb off your bike is not going to make a vast (any?) difference in the 'real world'.

So, : does anyone have a direct comparison they can offer? New bikes are lighter. Faster, well, as ever that depends on the rider not the bike. 531 isn't really in use for race bikes any more - it's too heavy. 20 years ago a standard race bike would be 22lbs and a super-light, somewhat fragile bike could be 19lbs but wouldn't be up to the job for regular use. Now a standard race bike is 19lbs and a super-light, but still strong one will be 16lbs (Trek Madone for example). The newer gears are lighter dispite more cogs. The combined brake/shifters levers are now as light as the old brake levers were after a long time in which they were heavier. There was a period when bikes got heavier, mostly due to STI/Ergo units being heavy, but they are now very light.

So, > does anyone have a direct comparison they can offer? Frames of equivalent cost are generally lighter now. The best modern clincher tyres are slightly faster. Rest of components, I'm not so sure.... I've completely rebuilt my 1980's "fast" Raleigh Royal tourer with modern equipment of the equivalent/higher price level and it's now *heavier*. Probably the only things that are now substantially lighter are the handlebars and headset. Dual pivot calipers are heavier than Weinmann centre-pulls, more sprockets equals more weight, MA2 rims no lighter than old Rigida/Weinmann alloys, Ergo combined brake & gear levers heavier than old brake levers plus DT levers, cranks still solid lumps of alloy, etc, etc. However, the better comfort and function makes the bike more enjoyable to ride than it ever was with the original spec, and the wider range of closer-spaced gears makes it faster, because I can ride more efficiently, despite the ageing of the engine! Clipless pedals help as well. ~PB |

This lead me to thinking 'are new bikes any lighter than the equivalent of, say, twenty > years ago?'. Of course new bikes are faster, unless purchased for a different property such as foldability. The effect of buying a new bike virtually expands mental perceptions of distance and slows perception of time to result in increased speed as a direct consequence of spending a lot of money on it ;-).

They are probably a few pounds lighter than some years ago and are thus 'potentially' faster. The cyclist must still be the most important component. I only ride mountian bikes and the upgrades from an origional old Boss thing to the current Marins has produced an impressive improvement in handling, braking and gear changing. These changes make me faster (a comparative term) but more importantly make the whole plot a more enjoyable ride. I love new technology and take advantage of it - but I do realise the principle limitation is me. John |

I managed to get my TT bike down to a shade over 19lbs - and I still use the frame and wheels. Tubing was 531SL (a rare breed) and I had drilled out bits everywhere. I've still got the slotted Zeus cranks in near pristine condition. John B |

Made me chuckle ![]() My new tyres convinced me I was faster, however my average speed is still the same. I thought that a long time on tyres flatspots them all around, therefore more tyre on the road. Then I realised that I was just giving it more |

I've still got the slotted > Zeus cranks in near pristine condition. I didn't really try to get a lightweight when I built my road bike 14 years ago. It tipped the scale at just under 20lbs when new. The key things that got the weight down: I am short so a 50cm 653 frame is pretty light. I have short legs so 165mm cranks save a few grams. competition 19mm clinchers and latex tubes. With a bit of work I could have probably dropped the weight by another half a pound by trimming the saddle, seatpost and handlebars. Then again losing a kilo off the bike won't make much difference when I weigh about 90kg (though this is dropping rapidly, I was pushing 105kg last summer and quite unfit) which is a bit much for my shoe size. (OK, I have a not so nutty theory that obesity charts should be based on shoe size rather than height. That is partly because when I was riding 200 miles a week, fit as a fiddle and had just got back from a month walking/climbing in the dolomites I weighed a tad over 70kg which puts my 165cm into the 'seriously overweight' category. Total bull. Yes that does make me a 'stocky' build but my target weight of 80kg is generally right for my shoe size of 9.) ..d |

I've recently bought a new bike in an attempt to get back into shape (and maybe even race again after a 21 year gap!) and I would make the following observations comparing my new bike (Airborne titanium) to my old steel bike from the early '80s. New frames (and especially carbon forks) are a lot lighter - easily a pound plus for the frame and half a pound plus for the forks. Other bits such as handlebars/stems also seem a bit lighter. But many other components are definitely heavier, especially wheels/tyres. My old 28 spoke sprint rims and ultralight tubs must be a pound lighter than my new Campag Neutron wheels, although the new wheels are staying perfectly true which the old ones never did. My old 5 speed alloy freewheel weighed next-to-nothing, as did my pedals, brakes and tubulars. I was a total equipment nut when I used to race and weighed everything down to the spoke nipples. My road bike weighed under 19lbs in 1982 and it wasn't equiped with megabucks components, just carefully chosen lightweight bits. I don't believe many people would do this today; bikes are now bought with groupsets so you get all of the good and bad bits from one manufacturer just so that the bike looks aesthetically pleasing. Overall I don't reckon there's that much weight difference between a good steel-framed bike (say Reynolds 753) from 20 years ago and a typical aluminium bike now, but getting a really light bike is now possible without spending a year's salary and without sacrificing strength and durability.

The act of purchase is reason enough itself surely? Or perhaps it is the knowledge that you are setting one free to live in it's natural environment? Graeme |
