My 4 year old Giant Contact SL dropper is finally dying (good riddance!) It seems all droppers will have issues at some point so may as well get something reasonably priced and replace when needed. I'm settling on PNW due to their good reviews and, most importantly, lifetime warranty. But I'm undecided between the Loam and The Rainier. I know you can adjust the air pressure on the Loam under the seat. Is this a better construction than the Rainier? Which air cartridge design will be more reliable in the long run? I'm just wondering if there's any mechanical benefits to getting the Loam over the Rainier. BTW, I am a heavier rider.
