I really want the force cx1 crankset. Should i get the BB30 version or a the gxp and run a kcnc/praxis Convertor?
Reason being the bearings might actually last longer and is easier to install/remove
BB30 bearings are not as well shielded (almost can say there's none) as compared to GXP and this usually means more frequent BB bearing changes compared to GXP.
Even Cannondale who is the founder of BB30 is moving to PF30.
Between BB30 and GXP, I strongly feel that GXP is better.
BB30 crank is lighter and supposedly shifter
if your frame allow a BB30.. then make full used of it..
and get the BB30 Crank.
i dnt have a cross but my MTB is on BB30. so is my Road. and i am using Sram X0 BB30 on theMTB and Red on the road
what i realise is that for my MTB, regular maintenance is a must. I pack my BB30 with grease and repack them when i have muddy session.. of cos i will clean them out first before repacking...
Of course, I'm still debating whether I should go with SRAM CX1 or piecemeal a Shimano 105 5800 w/hydro. I've always used Shimano on my bikes.
This is weight weenies..

The first great deal i got on ebay for the crank was GXP, so i went with it. Installation was a cinch, operation is flawless. BUT, the adapters weigh 85g, and the GXP is heavier than the BB30 crank (forgot how much) -- and honestly, the extra 100+ grams is eating a hole in my head! I want it gone, and wish I had just spent a few more bucks on the bb30 crank. Is it worth it to have to replace bb30 bearings every season to save 100g?

Get lighter skewers and find something else to get that weight back .

There is almost no difference in the sealing between SRAM GXP and press fit BB's. They are both just little plastic shields with a standard sealed cartridge bearing behind. They'll last almost an identical amount of time if used in the same conditions.
A BB30 Exogram crank will save a huge amount of weight and the different bolt pattern will be of no consequence if running 1x10.
