Some folks love 'em, some folks hate 'em.
Debbie had one on our first tandem and wasn't a big fan so we removed it and she's never used one since.
- They take the sting out of big bumps that captains neglect to warn their stoker's about.
- They can be set up with either fast or slow progression to suit different riding styles:
a) Aggressive teams usually set the posts up so they are very stiff to guard against "pogo" action; they'll still deaden the big bumps while providing a firm foundation for pedalling efficiency.
b) More "sensitive" stokers can have their posts set up so they soak up just about everything - kinda like an air-ride seat on a truck. For some stokers, if it wasn't for their softride beam or shock post they probably wouldn't ride a tandem.
- If they're not set up properly they can mess up a stoker's riding style/pedalling efficiency.
- They add some weight to the bike; hey, some folks count grams.
- You have to have enough exposed seatpost distance available to ensure the post will work with your stoker's minimum seat height position. If there is only an 1" of seat post showing on a tandem a shock post probably won't fit on the bike.
- Some of the early models (Tamer) were not as durable as they needed to be and proved to be problematic until stronger hardware was installed.
- Unless you use a parallogram model (Cane Creek Thudbuster - http://www.mtbtandems.com/images/thudbustersm.jpg
), there will be some maintenance required to ensure the post doesn't develop a problem with stiction.
- Single bike Roadie's will never understand why you need something like a shock post.
So, there you have it. RockShox makes good products so, for $60, it might be worth giving it a try. You can certainly spend a lot more on one. As casual riders it may be just the ticket!!!
