Material and joining choices

Hey guys I was wondering what the pros and cons are to certain ways some companies make their bikes. For instance I am looking at a steel bike thats made with

True Temper Ox Platinum thats Fillet Brazed with brass I think.

Does this sound good? Is this material comparable to reynolds 853? which I hear all good things about.

Also I have heard some bad things about fillet brazing. That it is like gluing and isnt as strong as gas tungsten arc welding (tig). That during the brazing process you are making the steel weaker, ect..

Any input on a bike constructed with these materials please let me know. I am looking for a new bike and I am a big guy and would like reliability and strength first and foremost since I weigh 250lbs. Thanks

250? have u ever consider to get one of these two?

Actually with the blue one you can run time trials, just change the sprint handle bars for a super man handlebar and you are all set.

There is a lot of mis-information in this industry. All I can say is that a brazed, fillet brazed or welded joint done well will be much more than adiquate for your needs. There is no functional difference between these methods in day to day riding.

True Temper Platinum is a similar tubing spec to 853 and in 13 years I have never had a problem with it. BTW, I have made plenty of bikes for guys of your size (actually you would be kind of small) and used either platinum and 853 interchangably with no issues.

A TIG welded joint is very strong, but a properly done filleted joint, because its radius is so much smoother can be equal or superior in fatigue. TIG welding is quick and requires no after weld preparation and therefore is much more profitable for bike companies. That is one of the main reasons why it is so prevalent today on steel bikes.

All the best,
