Great! BUT not that cheap compared to Motolites which come with pads etc. And can't find them to buy anywhere in UK/EU .. basically I want to run 650b wheel in 26" frame which according to this needs just 12.5mm adjustment each side: http://velo-orange.blogspot.co.uk/2011/05/converting-lht-to-650b.html

26“ to 650b conversion details: Most classic mountain bikes and some popular modern offerings such as the Surly LHT (26”) have adequate clearance for all of the smooth tread 650b tires. A 650b/38mm wheel actually suits the dimensions of the LHT better than a narrow 26”/32-38mm wheel, which leaves gaping clearances and unfamiliar handling. Conversion simply relies on a brake with 12.5 mm of vertical adjustability (half the 25mm difference between 559 and 584). We have already identified that Tektro CR720 brakes work at the top of their range, as did a prototype Grand Cru brake hanging out in our shop. Of course there are a few v-brake designs that have been around since the 90’s with loads of vertical adjustment as well.

Penultimate comment suggests 16mm up or down with these http://www.probikeshop.com/en/gb/elevn-technologies-brake-adaptors/103473.html

Or http://www.ukbikestore.co.uk/product/383/pxvb00/promax-p-1-linear-v-brakes.html have 35mm adjustment and come in mini v too...

If this is anything to be relied on then they will work! https://www.flickr.com/photos/franklyn/11259990165/in/photostream/

Both brakes offer a whopping 35mm of vertical pad adjustment, which the Henderson says is 30 percent more than other brakes. Perhaps this pad adjustment would allow you to run your dad’s 27″ wheels (bigger is better, right?), or if you’re really lucky, 650b wheels on some 700c bikes, if we did our math right (there’s a 19mm difference in radius from a 650b wheel to a 700c wheel, so if the pads are on the high side of the 35mm slot on a 700c wheel, you might be in luck, but don’t trust us, and YMMV).
