Vision, a recumbent tandem maker from the USA, used to make IPS cranks which allowed either captain or stoker to stop pedalling. I understand that they could be retrofitted to ordinary tandems also.

Total capacity is difference in biggest and smallest chainring added to difference in largest and smallest sprocket.

How about "I would not purchase anything from XXX again and will pity those that do."?

Rohloff doesn't make a 14t cog.

I know a lady who has a 48 x 13 Rohloff on her skinny-tyred Moulton. Running a 15t reversible cog means the chainring has to be too big. The 13t cog has a slightly wider chainline than the reversible cogs.

I've ridden a Cambiogear many years ago but there have been a number of expanding chainring (or sprocket) systems.

Absolutely need a shorter cable pull than a V-brake lever provides.

L'Union des Audax Francaise organised an Audax in 2003 that basically followed the original route and a similar timeframe. Only 1 or 2 Brits rode. It was a group of about 100 riders with lead and follow cars, scheduled at 22.5km/h riding average, so the mostly major roads weren't too much of a hassl...

My partner has a leg length difference and has different length cranks on some bikes (SPD pedals) and uses spacers under the cleat on other bikes (Look pedals). No problems during up to 17,000 miles annually.

Have not tried to get a warrantee as yet; it has been a busy couple of weeks.

My partner's Phillips battery taillight died after a few months. Disappointing as it was otherwise a favourite.

My partner fits Pogies to her commute bike whenever it starts to snow.

Schwinn, the USA-ian Raleigh-equivalent, had a custom department where the Paramount frames were produced. Back in the 1950s or so, all of their Paramount framebuilders were women.

With bar end shifters, I know what gear the bike is in at night. Judging by the amount of cross-chaining I see on other bikes after dark, STI and similar have a major disadvantage.

Fit a heavier front tyre and tube. The gyroscopic thing.
