Thomson Aluminum Elite 410mm Seatpost
The Thomson Aluminum Elite seatpost features double the fatigue life of any other production models tested. The tube and head of the Thomson seatpost are integral-machined from one single piece of high strength 7000 series aluminum. The head is not pressed or bonded in. This allows for superior strength and minimum weight, allowing higher strength at low weights.
The Thomson seatpost design incorporates a bending fuse to prevent catastrophic failure. All brand-x seatposts we tested - every one of them - failed in catastrophic failure with the seat and clamp components - and sometimes pieces of the tube and head - flying off in all directions. This type of failure would dump the rider.
The Thomson seatpost has a clamp, head, and upper tube strong enough to withstand 350-foot lbs of torque. The tube will start to yield and bend at the seat tube clamp at about 250-foot lbs of torque. Remember all brand-x posts we tested flew apart at less than 150-foot lbs of torque. Under severe impact the Thomson seatpost would bend slightly and allows the rider to come to a safe stop or finish the ride.
Put this on my mtn bike in 2002 and havent had a problem with it. I have my post hiked up pretty high, and it hasn't bent or anything in more than 10 years. Never had to tighten or re-adjust from things slipping. Great part to add to any rig.
Heavy duty quality you pay for what you get - easy to dial in set angle no creaking - happy customer
Flawless as is expected with Thompson , American made if that matters, work of art that performs perfectly . Follow their instructions and it should out last your frame.
