I also wanted to check his claim
placed a new battery in my calipers and had a small measurement party

Once again, it was not just a "claim", as witnessed by the image i posted to try and slow down the trolling on this forum.. lord knows it will never cease completely.
Glad they seem to have gotten their QC issue under control. The Thomson Pricing is still WAY out of line....i guess those bags are really expensive?
I spotted an XTR box on CL the other day... no part, just a der. box... $17, but Free shipping... someone should snap it up!
Update: did some checking on Thomson .. they state that the alloy is 7000 aluminum... Can't find that specific alloy listed Anywhere except in relation to their parts... It seems the closest commonly manufactured aluminum 7000 SERIES alloy is 7005... then 7010... next is 7021, 7030, then 7050, 7070... and 7075 is the Normal alloy for demanding applications.... variations exist, as some applications may call for specific characteristics not covered by the production mixes. 7005 is used by multiple Bicycle Frame builders, as is 7075... the 7075 is preferred for it's strength but tends to be more easily fatigued into failure. Boeing uses a lot of 7075... i'll ask my buddy that works there if they specify careful Heat Treating/annealing, and/or stress relieving on the parts she's made for a few decades now...
ever seen the "Thrust Link" on a 707? it holds the engine to the wing.... it's aluminum.... and one 4" long grade 5 bolt rated at 275,000lbs. shear strength.... grade 8 bolts crack easier under high frequency vibrational loads... i'd imagine those thrust links and bolts were regularly inspected and replaced... my neighbor worked for Alaska Airlines for 30 years... i'll ask him next time i run into him...
Thomson's "Masterpiece" posts have a weight Limit of 200lbs. listed On Thomson's Site..... didn't read much past that weight limit spec...... Heads-up, Clydesdale Class! YIKES. I wonder if their steering stems call out a Weight Limit too... hmmmm... pretty sure I won't bother looking... i have a Thomson stem on my Commencal right now, and i'm a definite Clyde-class rider.... sharply machined diameter changes create stress risers in any material... even a tiny radius at a diameter change improves the durability... just sayin'...
As to the Pricing.. Thomson punishes anyone that sells their products below their pre-determined retail price.................. NEXT!
