i posted this as a reply to another thread. but i'd like to know your guys views on what i was told by my lbs.

i was down at my lbs today where i got my giant tcx1 from. i was enquiring about the possibility of getting a set of alloy forks. i just don't seem to be able to settle down when riding with the carbon forks it came with, my reasons to be unsettled is that my scott genius ltd full carbon fibre mtb (£5000's worth) snapped in half due to a manufacturing fault (fracturing my eye socket and wrist and i was knocked unconscious for a short while). the frame was replaced by scott and the bike rebuilt by lbs, but i ebayed it.

the bloke at the lbs (craig at rideon in rossendale) is very knowledgeable and is involved in quite a few research and developments (bike related). rideon are giant dealers and craig goes to all the meetings a dealer has the opportunity to goto. he's been to a few where giant rep's talk about quality and prices and some others where they demonstrate the manufacturing process and quality control.

apparently not all cf is the same, i.e giant get the actual fibre's from the same place as boeing and f1 teams. in other words they get the best available, then they weave it in house and produce the components in house and keep a tight grip on quality. apparently giant have the ethos of it has to be 'fit for purpose' (which causes passionate arguments at dealer meetings, dealers want cheaper bikes to compete) and not built to compete with 'boutique' brands on lightness (eg, pinarello, colnago etc etc) the boutique companies buy in the already woven cf matting and 'swatch build' their frames with the ultimate goal being lightness and stiffness (fair enough, horses for courses).

giant actually build and have their bikes tested to some crash test standards (craig said EN summat or other) and are heavily involved with improving the standards of all bicycle frames and forks. craig says he really believes the company (giant) operate a show all policy and gets monthly emails regarding failures and recalls. he reckons in all the time he's been a dealer he's not heard (not even on the grapevine) about any problems with giant cf frames or forks.

now i'm not naive enough to believe everything i'm told by a dealer (obviously he may have an agenda) but craig seems to be a straight up guy and wouldn't sell cf mtb bikes until he started being a giant dealership.

what do you guys think? has he been straight with me (or giant straight with him).

i'm particularly happy with how he told me giant make their cf forks; a swaged end on an alloy steerer tube and then inserted into the machine that bonds the tube to cf & resin, i.e., not cold glued into a crown like a lot of companies used/do.

ribble bikes was one of the companies that was mentioned in the cheap chinese carbon category.

Threads like this are slowly putting me off CF bikes. You can pay £5000 for a bike and still have it snap in half?

I think I'm going to stick with my Reynolds 531 frame at the moment.

I watched the trek factory on sky 3d very interesting and made pretty much same as you have described giant

Some of the cheapo ebay carbon stuff have crash standards EN certificates if you believe them :smile: They've posted the certificates on their site and footage of testing. Possibly coming from the same factory as the Giant in your m8's shop.

You are going to get stories of broken carbon be it el cheapo or not but whether the chances are lowered because it's expensive, I dunno. BTW its the resin that's the important bit but not many companys spout their mouths off about that, they just confuse with their marketing nano this/ that babble .

I have 3 cheapo chinese bikes and cant fault them as one has taken some punishment and I still ride it. I know my Jamis ( USA my %^&$) comes from the same factory as Raleigh and some other brands, My tt bike - no name feels super solid as does my track bike. However my friend bought one for £200 from ebay and got a cracked chain stay after a month and the braze on front mech hanger thingy wasn't rivetted on properly, although I feel his missus could be to blame for the crack as it was deffo banged and he said it was not touched.

My Scott Addict bike was made in Taiwan and funnily enough........ Giant are Taiwanese. You have done right by asking about other peoples experiences then make your own judgement. Personally at the time I thought I was taking a risk with the cheapo stuff but looking back I think I made the right choices for myself and my budget.If in doubt you can get alloy frames just as light as carbon ones.
 
I think the Trek frames used to be made in the Giant factories not sure now though.

^Spot on, and still do AFAIK, (maybe wrong about now, but they definitely used to do) They may have been specified to Trek's own geometries, but Giant built them. There's a link knocking around this site to a very interesting article about who makes frames for who but I can't find it at the moment, I'm sure someone will be along with the link soon :thumbsup:

They can't afford to make everything in the US thats why the majority gets outsourced to China.Ill be pleasantly surprised if it was true though.

Actually looking at their website ( bored lol) I would say a minority of frames made in US, their higher end stuff.






'Is my bike made in the USA?
We continue to produce many of our bicycles in the US with a focus on our higher-end OCLV carbon fiber offerings. All of our bikes are designed and engineered at our headquarters in Waterloo, Wisconsin though select road, ATB, comfort, hybrid, urban and kids' bikes are produced by Trek-specific overseas vendors. Bicycles produced overseas follow the same stringent quality standards as our domestically built bikes. No matter where your bike is produced quality is stock on every Trek built.

Still have questions? Contact Us'
 
AFAIK the last mass manufacturer to build their frames in the US was Cannondale, but since the introduction of the CAAD10 all the manufacturer has been outsourced to the Far East, (including the CAAD10 I should add).

Some skirt the issue by bigging up the whole, "Designed in the *insert country of choice*", or "Built in the *insert country of choice*". but designed and built are very different animals from manufactured :whistle:

I'm not sure that "he gets monthly emails regarding failures and recalls" and "he's not heard (not even on the grapevine) about any problems with giant cf frames or forks" really square up!

No one has seen the trek factory on skky then because they sure made them on there and claimed that it is all in house

Any fool can put together a carbon fibre frame and fork that looks the business in the shop, but building one with the requisite performance properties is a highly technical process. The fibre/weave properties themselves are directional and laying up the layers requires research-based knowledge. For example, Specialised have used McLaren's research team to assist in building their S-Works pro bikes.
