Weird lump on steerer tube

[David Goldman]

just unboxed my new Soma Grand Randonneur frame and upon inspection of the steerer tube I came across this “bump” don’t really know what it is or if I should be concerned. What do you think?

Send the picture to Soma. 

9/8 butted steerers are so strong i seriously doubt that is an issue. But it is very difficult to see anything with the black color.

Michael, the Grand Randonneur has a 1" threaded steerer, not 9/8". I agree about just sending a picture to Soma to see what they think.

Looks like a little stray braze. You could verify by sanding off the paint to see if it’s the color of brass/bronze.

Sent some photos to Soma who sent it on to the factory, likely just braze or paint. Regardless, not deemed a safety issue. On with the build!

I had a lump like that on my steerer tube when I was about 17. Very awkward to ask about it, but the doc let me know it was just a lymph node infection. Ibuprofen for a week or so eliminated it entirely. YMMV.
