Whats out there?

I've found Jiangwayne, which I don't really like.

and Taida which isn't quite 44 (43.6)

Am I missing any others?

Do you have a listing for it? I haven't came across it in their catalog, only OEM replacement.

Well I ordered 2 of those 44mm Stroke Dio AF18 CMR from DynoScoot. Never heard of him but he sells a lot on ebay. Ordering the cylinder very soon too. Let the games begin.

Stock rod stroke ratio is 1.93

Most ministroke cranks have a rod stroke ratio of 1.82

Modern high strung streetbikes are 2.0+

My build will be 2.07 with a 91mm connecting rod. Ordered today from a local shop as they had them cheaper than I could find anywhere. ProX 03.1102 Note that the big end is 1.5mm bigger, and will need to be resized (width), or the crank modified. I think the latter so I can use the wider bearing. You could also use a ProX 03.2104 which is 2mm wider on the big end and 1mm shorter @ 90mm and give a rod stroke ratio of 2.05.

Zoom.

Got them today, The cranks are very nice quality, good machining, nice grinding on the bearing journals, nice threads and splines.

The rod is kinda wimpy. It looks like a 2AB rod without the words on it. Im tossing these rods anyway so no matter to me. A fella could throw a Pro-X rod on there and have a stout crank.
