I dunno if lighter than CT2 (assuming that's what Stronglight you're referring to), but it's probably very close, or close enough.
My friend is going with Praxis "Clover" model for both the 110 as well as 39/53. We were going to put CT2 rings for the M3 39/53 setup, but he wants the same style of Praxis rings on both setups. The compact will be used for hilly races and extensive hilly training.
Like I said, the Praxis "Clover" looks terrific on the THM M3 spider, it matches perfect in terms of mounting interface on spider arms/chainring bolt area. Can't say the same for SRAM Red spider (I matched it up, it looks sloppy on SRAM Red spider arms since they're just a tad narrower than Shimano. Rings like the CT2 similarly overlap a little on SRAM Red crank spider, which is one of the setups on the bike now and is what will be swapped out for the M3's).
I'm in NYC area, yes. Unfortunately my pal's bike is out in SoCal and frankly there's nobody I'd trust in the immediate local area to do the M3 install. Only folks I'd trust would be Signature Cycles here on east coast, but shipping a bike cross country for a crank install is a little silly. Maybe.
THM-Carbones couldn't recommend a shop out there that they'd suggest for install (I asked them, and they only said it comes with complete instructions for installation).
can't wait for fairwheel to get the m3's in stock--i'm helping a buddy put one together for his bike.
we have the spiders and rings (110 and 130 spiders, praxis rings), now just need the arms/spindle.
the wait for inventory is driving us nuts!
it'll be a really cool setup when done. the praxis rings match the width of the m3 spider perfectly, i.e., no overlap or mismatch in width.
great, I was thinking of using stronglight rings if ever I get them. are the praxis lighter? are you from NYC ?
