NARROW AND MEDIUM WIDTH RIMS
     ============================

The following table details some choice rim models in the 16x1-3/8", 17" and 20x1.5" ranges, which theoretically should be available in a shop somewhere in the world (or has been until recently :-). Other possible sizes (like ERTRO 340 [=400A], 355, 390 [=450A], 440 [=500A], 451) have been omitted either because they are too obscure or simply too large to fit in (most) 20" Moulton frames.
Only rims that have a reasonably narrow section, i e with an "inside", or bead-seat width of approximately 22 mm or less, are listed. Tyres that fit such sections should ideally not be wider than 40 mm nominally.
An overview of basic specifications for narrowish tyres can be found here.

Please also refer to the rim/tyre size compatibility overview at the bottom of this page.
