Thanks, great info!! I think we'll give some 32's a try.

We're fairly new to tandeming and have only ridden our bike, which is a Santana Arriva from the early 90's. My wife loves it and doesn't want to try anything else, I on the other hand, would love to test a few other bikes. I appreciate you taking the time to explain the changes to your Santana, sounds like you aren't afraid to think outside the box and have found the perfect bike for your team. I like the paint job!!

Thanks we are very happy with it. I would like to try a carbon bike with wide tires but don't want to spend the money to commission a one prototype by a builder that doesn't usually build that type of bike.

When looking for 32mm tires we found the choices few for fast flexible tires. Maybe others can give you some ideas.

It is a Santana so hubs are Hadley. Found them very high quality with easy maintenance. Mid range in weight
Spokes 14/15/14 double butted - 36 per wheel with brass nipples
Rims - Started with Synergy but Velocity had a bad batch and replaced them under warranty with A23 - 431 grams.
Total wheel set weight 1149 rear + 891 front = 2,040

Velocityusa.com only shows A23 in 700c. Do they make them in 650b but not show them on the web?

They are a nonstandard offering commissioned by Longleaf Bicycles available in 32 and 36 hole drillings. This is a lightweight "tubless ready" rim. That means it is difficult to mount tires because the diameter is on the large size compared to some rims.

Most people seem to use the Synergy 650B rim.
