Jipe 58T fits fine with that tensioner.

glye is correct on his statements around the 9-32 / 9-36 11 speed mods - see my comments up thread from my version of the same modding “journey”.

I would take slight issue with the proprietary comments for the Sun Race - the outsides and cassette are pure Shimano standards namely Capreo and 11 speed cassette spacing. Whilst the product is niche and limited to a couple of folding bike OEM’s Sunrace themselves are huge . I would make a WAG and suggest they are probably bigger than both SRAM and Campy from a groupset/gearing product sales volume perspective - guess who owns Sturmey Archer!

The 9 speed Sunrace kit is available from a US retailer who ships worldwide - check out Soma Fabrications in the US.
