Define ‘BB part’, is it the shell, downtube, seattube, chainstay, or the interface of one of these that has cracked? I’d be surprised if you cracked the BB shell.
What’s the history on the frame? Excessively spread? Thrashed hard every day or ridden to a cafe on Sundays? Rider weight? (i.e. is this failure due to use or is it a fabrication defect?)
I think it’s poor form on Surly’s (Dirtworks’? If so, contact Surly direct) part to refuse warranty simply due to repaint. Blasting and paint/powder won’t affect tube strength/weld integrity. Frame mods, possibly.
It’s TIG welded, so not quite as easy as brazing in a new tube/BB, but any decent framebuilder should be able to repair it for you. Try Saints Fabrications (@St. Kilda Cycles), Ewen (@ Cog Bike Cafe), Gripsport for a start. Take some photos, send them an email, see how you go.
Surly™ frames and forks are guaranteed to be free from manufacturing defects for three
years from the original date of purchase. If we screwed up something in the manufacturing
process that resulted in the premature failure of the product, we’ll fix or replace it at our
discretion. This warranty is for the original buyer of the product and is not transferable. It
should go without saying that we won’t even consider your warranty problem without a
This warranty doesn’t cover damage resulting from any sort of riding other than “normal”
riding, and the inevitable wear and tear resulting from “normal” use. Surly
products are built to be used vigorously, and we wouldn’t expect you to treat them gently.
However, we can’t be responsible for the inherent danger to body and property you face
each time you throw your leg over the top tube. We’re hip to the “just riding along” phenom-
enon - and frankly, we’re just not having it.
Sorry, the paintjob isn’t covered, nor is any damage that happens to you or your other
components as a result of any failure of one of our products. Lastly, if you modify or
neglect our products, we can’t be responsible for them or what might happen to you while
you’re using them. We hate to spell it out, but hey, it’s the 21st Century. We’re known to
back up our products, but we’ve seen too many peoples’ parts come back to us that were
not defective and did not meet our warranty guidelines. Save yourself some time and
shipping money by reading this and making a decision for yourself. If you and your shop
think your Surly product is worthy of a warranty inspection, please return the
product to the original place of purchase, accompanied by a sales receipt. In the unlikely
event that this is not possible, call or email us and we’ll do our best to get you riding again.
Failure analysis reports can get kinda destructive :evil: :evil: :evil: :evil:
If it is a manufacturing defect you could get a new bike from surly if it isn’t you get your bike back cut into little pieces and mounted in phenolic resin
