I recently acquired my first tandem, a 2001 or so Burley Duet, and have a few questions about parts. Note that this is a road oriented tandem, and we will be using it on the road.
1. We had to flip the eccentric to the high position to reduce the saddle-to-pedal distance enough for my girlfriend to be able to captain comfortably. Are there any unforseen consequences of doing this? The bb is the type with set screws on the top. I did read somewhere that the eccentric is ususally assembled in the low position to lower the center of gravity of the rider, but it is not clear to me that this would change the geometry meaningfully.
2. The captain seatpost has a super-beefy double-bolt seatpost clamp that I think may actually be a re-purposed unicycle seatpost clamp. I like the idea, and it has not come loose even once in our first week of riding. However, swaping it out for a shorter clamp might remove the need to flip the eccentric. Any ideas on which compromise to make?
3. The bike has drop bars with shimano 105 brifters (I'm assuming short pull), and direct pull levers (I'm assuming long pull, but not sure). I really like the braking action, but I'm curious if Burley has been known to deliberately use long pull brakes with short pull brifters to increase the braking leverage on their tandems. The arms of the direct pull brakes look like they might be shorter than typical.
4. Is there any reason I shouldn't use cyclocross style in-line brake levers on a tandem? The intent is to help my girlfriend brake more comfortably when she captains. She can currently brake very effectively, but she is more stretched out than she or I would want to be when she is in the drops. I'm new to this type of lever, and the stakes are more than twice the usual, so I thought it prudent to ask around.
5. Anyone know what the modes of failure of the Thudbuster suspension seatposts are? I weight more than she does, and we switch off too often to change the elastomers each time. The manual warns users to never use softer elastomers for those recommended for their weight. Should we always ride with the elastomers for my weight, or should we disregard the manual and find a comfortable ballance? i.e. Are we just risking the discomfort of the stem bottoming out if we use too soft elastomers, or would our hubris be rewarded with an asploding post? This is a new LT version.
