Well nearly completed the build once i'd sorted the Di2 routing and the SWorks cranks with direct mount chainring, but hit a snag with the brakes.
Am reusing parts of my I-play 105D, and although the Niner is a smaller frame the rear brake hose is too short, so have had to order a new one, and then realised that the Niner is designed for 140mm discs and mine are 160mm , so a search for some spacers turned up a great deal on Planet X £3 per brake with Ti bolts. just have to wait for the postie now.

full build is/will be.

How does it compare to your Iplay frameset?

Exar, haven't had a chance for a decent ride on it yet to comment on the ride, but generally the frame is built with a lot more finesse than the I-play, less chunky around the chainstays and brake mounts and generally more sculpted lines than the I-play, weight wise isn't a fair comparison as they are different sizes. Will comment more once i've got some miles in and dial the fit in.

Overall the weight is reasonable at 7.7kg, given the rear mech and cassette weights, plenty of room to drop weight from the wheel-set if i went carbon rims and tubs. A more expensive cassette with an XD drive and XD free hub would drop up to 0.2kg on its own.

(an update) slightly disappointed in the weight so i have ordered an XD driver (one advantage of the American Classic hubs) and SRAM X01 XG 1195 cassette which should drop the weight below 7.5kg and expand the gear range slightly, 10-42

works out at about £1 per gram weight loss, so not a bad cost to weight saving ratio.

I have a 2015 BSB RDO and it will take 160 rotors with spacers I believe. You might not need the 140s.

Yepp thanks realised that, ended up going with some Ashima adaptors as they are light and pretty cheap, The Avid ones i tried didn't seem to sit the calliper flat against the mount.

Weathers dull and sleety so no pics yet.
