A friends high end Marin alu hard tail cracked where the seat post enters, the frame was replaced swiftly and without fuss.

I bought a quality s/h road bike once, the original owner bought it brand new in the autumn at a knock down sale price, hardly rode it and by late winter was selling it to fund a motorbike purchase. I effectively paid 50% of the sticker price it would have had in the shop 6 months prior. Over the years I have seen and heard of a couple of real bargains but not of a type I wanted at that time or if I wanted it couldn't afford it. When I once did set out to buy a good bike second hand I got fed up wasting time and petrol to look at what quite frankly was junk (or maybe I just expected too much). My policy now is to shop around for year end specials; nice, shiny, untouched with statutary and manufacturers guarantees, then go and ride. Pete |

You need to be a lot better informed to buy a second hand bike than a new one. Not only must you be able to appreciate the difference in quality between the loud, heavy crap and better stuff but also the difference in a reputable manufacturers range, where they may start with bikes costing £300 and range up to near £3000. Then you must be able to make a mechanical assessment. At least with a new bike you can generally apply the rule of thumb that, with few exceptions, the more you pay the better it is and of course you have consumer protection. Pete |

Yes I agree. For amusement I checked some out in M*kro once, no comment! In this age of nannyism it seems odd that reputable businesses can sell a safety critical device like a bicycle the way they do, it seems a different standard applies between, say, electrical goods which must be CE and Kitemarked and a bicycle sold in a box to be set up by "Dad" who may be perfectly clueless. We no longer expect, nor trust, people to fit a 13amp plug but consider it acceptable to sell a road going machine that a novice could exceed 30mph on with the right descent. Pete |

I don't know how the system works, but I'd be surprised if >a big-name brand didn't impose some kind of quality control (What >happens to the rejected frames?). > As far as I can tell from reading information from some of the manufacturer sites they have runs/batches of certain frames. I.e. tuesday morning would be lets say a Specilized 18" frame, tuesday afternoon might be the 20" version. Wednesday morning might be an apollo frame. The specialized frame may simply be that a frame order where as apollo it might be a contract for a 80% assembled complete bike. Companies like abeni seem to have options ranging from just the main frame to a completely assembled bike. They also do bike kits with no assembly at all (I quite like the idea of that one). There is also an option for standard design frames which is their cheapest option. They'll do a large run of an identical frame which they sell at low cost unpainted or painted. This option is for small bike builders it seems as they are available in smaller quantities like 100s instead of 1000s. These look to be the frames that companies like Edinburgh cycles or merlin use. There is a pecking order of frame builders in taiwan though. Giant seem to be the highest rated or at least one of the highest rated. A step down from them seems to be Merida (not sure I've got that name right). Nearer the bottom end is Abeni and Idealbike. None of the frames are bad though. >Secondly; The components fitted do make a difference, and while >upgrading is possible, it's cheaper (in the long run) to have the better >components fitted by the manufacturer who can buy them at a lower cost >than you. > I'm not knocking good components, my point is there are a lot of £300 bikes that really don't have particularly good components fitted where as others do for the same money. I'm only questioning the consistency of brands to produce good value models not buying bikes with good components. You can get basic tourney gearing on bikes upto £400. >Thirdly; If you buy a bike from a supermarket, you have to accept that >it may not be well set up, and that the staff may well have little or no >knowledge if something goes wrong.

Theres no reason to buy a bike from a supermarket because the same cheap bikes can be bought cheaper elsewhere as far as I can tell. Halfords tend to be as cheap if not cheaper for the same type of bikes with just the branding changing. >Fourthly; Heavy != strong. Light != weak.

Its just one of those things where the variables are enormous. However I do think that when a bike is trying to be as light as possible for performance reasons with aluminium replacing steel, tube thickness thinning down and triple butting in the frame on fairly standard size tubeing , spoke numbers cut down etc you are not going to have a stronger bike a lot of the time. >Fifthly; I don't recall anyone here offering any genuine brand snobbery. >There is good support for Cannondale, but they don't fit your >description of budget bike construction.

The point is they offer a generous guarantee on the steel frame, much longer than they have to but stick to the bare legal minimum for aluminium. Whats this reference to 'cast iron' though is that some sort of dig against steel frames again? ;-) |

No? I suspect you'd be surprised, then. In my experience lighter components generally are (usually considerably) stronger. Forged aluminium cranks, for example, are several times stronger than cast steel ones, and I strongly suspect that carbon ones are stronger still. Of course, they also cost a lot more. -- simon@jasmine.org.uk (Simon Brooke) http://www.jasmine.org.uk/~simon/ .::;===r==\ / /___||___\____ //==\- ||- | /__\( MS Windows IS an operating environment. //____\__||___|_// \|: C++ IS an object oriented programming language. \__/ ~~~~~~~~~ \__/ Citroen 2cv6 IS a four door family saloon. |

You'll get a one year old mountain bike for about half its new price; older ones cheaper.

I personally > would say the vast majority would have had a fair bit of use to a > massive amount of use. But you're wrong, I think. A substantial proportion of bikes get bought, ridden a couple of times, shoved in the back of the shed, forgotten, dragged out several years later and taken to the tip. More expensive bikes are more likely to be advertised second-hand than taken straight to the tip, but remarkably few of these bikes have seen any significant use. -- simon@jasmine.org.uk (Simon Brooke) http://www.jasmine.org.uk/~simon/ ;; Semper in faecibus sumus, sole profundum variat. |

That's confusing correlation with (implied) causation. The reason cast components often fail before forged ones has nothing to do with weight, and the cost of forging compared to casting is reflected in the price. To continue your example, I'd expect a really well-made forged steel crank to be considerably stronger than anything of the same dimensions that could be made by any method out of an aluminium alloy (none of these so-called aluminium components are made of pure aluminium, any more than pure iron is used in engineering. -- Joe * If I cannot be free I'll be cheap |

> >Data? People used to say that about high end aluminium frames as well >until EFBe fatique tested a whole range and all of the steel ones failed >while many of the aluminium ones survived. > > >Tony Well the long guarantees on steel frames is standard for bikes imported by conceptcycles and universal cycles. Other brands may offer lifetime frame guarantees for all frames but no one offers long guarantees for aluminium frames and short guarantees for steel frames. Steel frames always have guarantees as long as aluminium frames or they are a lot longer. Wasn't the EFBe tests based on steel frames designed to compete for lightness with aluminium frames? I'm making no claim that steel frames are stronger and can be as light as aluminium especially for light weight road racing frames. I'm just pointing out manufacturers of low cost steel bikes which are obviously going to be heavier than the aluminium bikes offer long guarantees on the steel bike frame even though they are a lot cheaper than the aluminium models. Maybe this will change when bike manufacturing moves away from using 7005 aluminium which is prone to cracking and better aluminiums like 6061 are more common which have equal strength across the whole frame and are not a mixture of heat treated and non heat treated aluminium. |

On the subject of frames failing, none of them are indestructible. I still have and use an old Raleigh Royale I bought second hand. It's made of Reynolds 531, reputedly a very tough steel that outlasts most other bike frame materials. Even so, after adding to its previous history with some severe touring use on a quite a high bottom gear by current standards, riding around places like the Wicklow Mountains, I found the seat tube had broken in two above the bottom bracket. -- Joe * If I cannot be free I'll be cheap |
