On a tandem, the captain or pilot needs more stand over than he (or she)
would on a single. To get a tandem started the captain must hold the
brakes while straddling the bike with his legs far enough apart for the
stoker to mount and reposition the pedals. It's also a bit more awkward to
get
Hi Bill,
I am looking to buy an Ibis touché. I am not sure of the exact size yet,
but I am afraid that it may be a small. What size is yours? Do you think
the Riv principles for sizing apply to a tandem? I would appreciate any
advice on sizing this tandem that you could give me (I am about
I've always heard that that you should go for a lower standover on a
tandem, which infers more seatpost showing. How un-Rivendell! ;)
Any Rivendellian would look at my tandem and say it doesn't fit you, and
they'd probably be right. But what the heck, it's the tandem I have, 350mm

My wife and I have been riding a custom made Santana Noventa for the past
several years our choice of tire size is 700x28 sans fenders. We originally
used Conti Gatorskins and then switched to Ruffy Tuffy's . We were once
part of the go fast crowd and actually considered the 700x28's to be a
We use 35 mm tandem tires, and as much as I like wider tires /hetres on my
single bikes, 35 seems optimal...there is plenty of useful flexion in the
frame of all these tandems, that wider (and I did have hetres on for a
trial on the santana) didn't yield appreciable benefit. That said, our
Tandems East http://www.tandemseast.com/parts/brakes.html has them, but
they will cost you. Also they are working with Co Motion on a replacement
now that the Arai is no longer produced.

Yes, I guess you're right, it's a balance between you and the stoker that
brings proportions... not only you.
At our size, if we'd both go on the same tandem, I'd try to build a 36er
tandem!
:-)
Like this one (but it's a triple)

With a 26 wheel, we have found 36 spokes to be plenty strong enough.

Wow, thank you all so much for the input. Pretty much confirms what I
thought that we would probably want clearances for up to 50mm with fenders.

offering, but wondered if the frame might be a bit

It's great!
But at our size, I wouldn't go with 650b. Why did you chose 650b for your
Sadly my Ibis Touche won't take much wider than a Jack Brown. I have Jack
Browns on there now, and a set of 35mm Paselas in the stash. If I could

would. The fork is ready to take fatties. I guess all I need is to move
We like Pasela Tourguard 700 x 32s for most of our tandeming. Our old
Co-Motion Speedster from 2006 accepted those tires with fenders but not
35s.
To run bigger tires we recently upgraded to modified Co-Motion Java. They
changed it a couple of years ago from a 26/559 wheel model to 700c/29er.
Speaking of Bilenky, we tested one of their tandems. It was equipped with
42 mm Grand Bois Hetre tires. We used it in a 300 km brevet, and set a
course record for that (hilly) course on it. I rode Paris-Brest-Paris on a
1946 René Herse tandem with 38 mm tires, but that was only because 42s

If one is on a timetable, Co-Motion is turning tandems around relatively
quickly. With a number of custom modifications and couplers, ours got to
us in about 6 weeks after design approval.
We have friends who are getting a 650b custom tandem for use with Hetres

Our Bilenky was designed and set up for touring. We run Marathon Racers,
