My seemingly endless experiments in search of a comfortable hand/arm/neck position on flat bars have taken me to a nearly bolt upright stance, using Jones bars, and I now “get” why he designs his bikes with incredibly short top-tubes. The designers of old roadsters and Dutch bikes knew a lot about this, which I’d certainly not got my head around before ….. you have to sort of “unlearn” drop-bar thinking and modern-convention MTB thinking.
I can’t pedal efficiently with a short reach… how do you get on?

Phone! E mail answering is an awful chore and doesn’t get done in a timely manner

The solution to that problem is cutting off the crank arms leaving the spiders*.

*Probably best to find some cheap right hand cranks (wanted ad) with a suitable BCD and cut them down, saving the current set for use with crank shorteners in future.
Exactly!

Re: Adapt a tandem to take a child

Sounds to me like the shop doesn’t want the job.
Somebody linked some bars which struck me as too wide for a child

Re: Alfine shifter - hand swap…

Keeping the same layout on 2 bikes is also sensible!
I found I couldn’t do drops where (from the ramps) you go forward for the brakes and also bar ends (on flats ) where you go back for the brakes; I didn’t always have time for a second go!

In a months time you will wonder what all the fuss was about.
I assume that a helmet (safety equipment) shouldn’t interfere with your view. I don’t wear one, and I certainly wouldn’t wear one which interfered with my view. How would I watch the buzzards and red kites as I ride along?
(Maybe I don’t get neck ache because I spend so little time looking where I am going?)

Re: Alfine shifter - hand swap…

My first thought is leave the gear shifter where you are used to and put the throttle the other side.

Without wishing to be controversial the many pages of this thread are a mix of personal experiences with a few bits of physics thrown in here and there. Though I respect the experiences of others I’d really like to see a decent scientific analysis that’s then proven by test results. Short of that I’ll be taking things steady and looking for feedback from whatever brakes I’m using at the time.
Without wishing to be controversial, do you have any experience of disc brakes on bikes? Having used both,
I’m of the opinion that tandem drag brakes and bike disc brakes need a different method of use.

Re: Techniques for braking on steep descents

Drum brakes (tandem drag brakes) dissipate heat into the big heat sink which is the hub, you can carry on doing that for a while before stuff gets too hot.
Disc brakes stop you faster than the old tandem drag brakes, therefore produce a lot of heat in a short time. The way to stop overheating your disc brakes is NOT TO DRAG THEM, but to let them cool for example by alternating front/rear braking.

I think you will be missing some fun with just a footrest.
I think you said you have 3 kids, I reckon it’s worth spending more money if more than one kid gets to benefit; although in my case it was spending time, very little money changed hands.

Yeh the stiff neck thing was me thinking back to when I road a classic roadie back in the late 80’s early 90’s with long stems that actually dropped the bars to almost inline with the top tube (at least mine did) , it seems on these gravel bikes they use a shorter reach stem which actually raises the bars as well.
So all should good ( fingers crossed)
……If that’s the last time you rode drops just get something secondhand to play about with riding position, now isn’t the time to worry about the details of flared drops gearing minutiae and all the other candy floss.
