One was definitely the weld, the other I'm unsure of. It could have been the heat weakened metal near the welds.
Both where cross country mountain bike frames, being used the way I ride my bikes I'm really not suprised they failed.
That is surprising because a good weld should not fail and even if your abusing it it should only be the metal near the weld that fails rather than the weld.

It was a *very *cheap frame :]

MrSmith and Tommy, you've both done your homework well.
As one of you pointed out earlier (I can't be arsed to check who) TIG requires more skill.
A skillful welder wanting to do a good job will choose TIG. There are more factors to vary (distance of gun from workpiece, distance of filler from workpiece, speed at which gun and filler are moved along workpiece, rate at which filler is fed in to weld area) but the potential for a stronger neater weld is greater. MIG (afaik - its been a while since I did any welding) has the feed rate of the electrode/filler fixed, so the rate of traversal of the workpiece is the only variable and hence easier to get right, however, it is harder to keep a constant distance between electrode/filler and workpiece especially when the workpiece is uneven - as the electrode is the filler, as it is consumed, distance between electrode and workpiece varies producing a poorer weld - something that is less likely to happen when a skilled welder uses TIG.Having said that, the angle of the nozzle to the workpiece can also play a part and can affect spatter and porosity of the weld. The idea is to get a good pocket of gas around the weld area so as to prevent the weld from oxidising. AFAIK there is no reason why a MIG weld cant be as strong as a TIG weld, but an unskilled welder will get better results with MIG than TIG.
Use of TIG is also a bit of a status symbol. If you can weld well with TIG you are demonstrating your skill as a welder.

Will they fit? Any reason I shouldn't get them? Anyone got some to sell?
Once again, thanks for the help!

if they are both 25.4mm then they should (WHich i think they are)

Found it in a different thread. You're right - thanks Slag.

Looking to get new sprocket on fuji track and wondered if anyone has any advice? What to look out for (like getting one so small I can`t shift it!)
Who makes the best value sprockets? Any on line bargains?
thx, P -

I'm thinking about laying my hands on a fuji track pro but can't find one in stock anywhere, anyone seen one on display anywhere in the london area?
(I need to make sure the carbon fork has got a blanked out area that can be drilled into for a front brake.... And i just need to see one coz they look spankin')

They're no substitute for their steel brother the Track. However, as I'm feeling benevolent there was one in Evans - The Cut (Waterloo) on Sunday just gone.

Saw one in Evans in Wandsworth too, I think it was a 56, although could have been a 54.

They are in loads of Evans, Wandsworth, The Cut, etc - look on their website:

But at £200 more than Biddle bikes, its must be the quality of the air inside Evans that allows them to charge that. Thats steep.

Cheers guys, finally found one at Evans in spitalfields (56) after lots of ringing around, it must be doing the rounds or something because they say it ain't at waterloo any more. I'm torn between the track and the pro still though...
Btw I bottled some of the air, £5 a pop outside the clubs? it's the good sh1t.

Or pick up just the frameset at http://www.thebikebiz.com/product_p/bk-trk-fuji03.htm

Evans will price match any UK authorised dealer on an identical product.
ShannonBall got offered a Steamroller at Winstanley bikes price I recall.

Don't like the 2009 colours as much as the 2008 personally:

Also new for 2009, the geared Connoisseur, very pretty:

A shame, I like the 2008 Fuji Track graphic, thought the 2009 is still better than the dreadful 2007 one which sorta screamed "I AM CHEAP! I CAME FROM HALFORD".

the bikes the same.. although they seem to, somehow, have picked an even worse seat!
the pro looks sweet tho!

The colours and graphics are similar but quite different. And yes the saddle is even shitter, if that were possible.

surely the graphics don't matter when riding at the velodrome?
mig can do good welds, it is fast and can be automated. I know tig is alot more skilled and slower and more expensive e.t.c, thats why I would take a guess that most mass produced frames are miged. Plenty of welds can still be good with mig.
The neatness can be important as I believe tig has a smaller area which effects the heat treating which will effect the length of the butting needed on the tube.
All this may be wrong so people correct me but it is what I have picked up from talking to various people.
