I've just bought a BB30 cross frame. I've heard nothing good about BB30 espeically when using in mud, dirt and water etc.

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

For what it's worth I've been using the realworldcycling.com kcnc/enduro bb30-gxp bottom bracket for two years. No creaking and the bearings still runs as smooth as new. Plus if you decide to buy a new frame in the future and keep the crankset, a gxp is usable in more types of frames.

I've heard good things about that adaptor

Is this on a road or cross frame?

I'm in a real dilemma as i know the bb30 is going to lighter and apparently stiffer (although real world differences i'm not sure)

some ppl saying BB30 is amazing and lots and lots saying its not

Frame manufacturers are not able to make the BB shell in such tight tolerances as required by BB30, resulting is either alot of creaking, or premature wearing of bearings.
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.

my honest opinion.
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...

I hope the OP doesn't mind I revive this thread. I am also in the process of building up a new CX. The frame will have a PF30 BB shell. If I decide to go with SRAM CX1, should I go with a GXP or BB30 crankset?

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.

Thanks.
