Glad to see it fits OK. A 42T Lekkie will deff. improve your chainline, if it touches the linkage place washers behind it. Use Locktite on the fixing nut on the drive.

I gather you are suggesting that it might be better to move the chain line inward (aim being the centre of the cassette). For the Lekkie, I gather the offset is 4mm more than the stock, so it may still clear the chainstay by the said minimum recommended of 3 mm; otherwise I wasn't aware that the Bafang chainring mount could cope with the addition of washers, so thanks.

Chainline aside, and in terms of speed, the 44T with the current 11-34 will apparently give a range between 29.84 kph and 9.65 kph at 60 rpm, which sounds reasonable. The 42T would narrow that range a bit.

Have taken up your suggestion and purchased a Lekkie 42T (not cheap at A$175);

I also decided to ditch the existing 9 speed 11-34 cassette for a 10 speed 11-40, that I had. Also then have had to order a matching 10 speed XT shadow clutch rear derailleur (said to improve hang on ability), 10 speed XT shifter and chain.
