    What PF30 set up are people using

    I recently got a new Ciclon frame. I am using XTR for the build and am in need of advice on how people have run 24 mm cranks on PF30 frames. I have looked at adapters for PF30 bottom brackets or press in a adapter and run outboard bearings.
    Thanks,
    JC

    +1. I have one for my upcoming Spearfish build. My initial impression is good.

    I have installed the SRAM PF30-BSA press in adapter with a Chris King MTB bottom bracket. Works very well once you realize the installation instructions from can lead to ruining an adapter. Best advice is press in, then thread in, rather than the instructed reverse.

    Kind of off the reservation, but I ran a Beer Components eccentric on my trail bike to fuss with the geometry.

    Very excellent quality and excellent support from Jim, highly recommended.

    21012 El Rey...I put a FSA BB30 bottom bracket on with Sram X9 BB30 cranks. I've got 1200 miles on the mtn bike this year since March 15th and the bottom bracket bearings are already wearing out. I've not replaced them yet but with BB30 crank my options are limited. I guess I'll try the Sram BB30 bottom bracket next. Unless anyone has other advice.

    Praxis PF/BB30 Conversion BB

    Hey guys..
    Thanks for the emails you've sent. Glad our Conversion BB is working out for you.
    We just wanted a really rock solid BB for Shimano Cranks that wasn't just a reducer band-aide like many out there, but rather a solid BB.

    If any more questions don't hesitate to email us!

    It looks like Chris King will be releasing a PF30 BB. I'm still not convinced pressing in the BB cups is the best solution for the end user, but a BB with Chris King quality does add a bit of reassurance.

    ^ Agreed. I went with the eccentric partially due to their being a slip fit having hardware to secure the cups to the BB shell.

    They are also going to have a PF24 version for us Shimano types. I just pulled my cranks for the second time to re-press the PF30-BSA adapter. The drive side likes to walk out about a mm or two.

    Sweet. I'll wait until Q1 to get a new bottom bracket then. Thanks for the info.

    For those of us using the truvativ pf30 adapter to the standard external BB cups, did you put in a 2.5mm spacer between the driveside adapter and the bottom bracket cup (Chris king in my case)?
    I already pressed in the BB and adapter before I realized I forgot the spacer, and am not sure what tool to use to press them out .
    Since both cups are pressed in, the standard 1 1/8 headset remover tool doesn't fit into the spindle hole. Any suggestions short of using a screwdriver to pound out the adapter?

    No spacer between nylon adapter cups and BB shell on '12 Ciclon with XT bottom bracket and XT double crank.

    I don't specifically remember so I just looked. Looks like a single black spacer on the drive side between adapter and BB bearing. Not sure how thick it is without taking it all apart. I built the bike, but it was few months ago.

    I have that combo on my El Rey. I first put the spacer between the drive-side cup and the adapter. I really only did so because that cup, specifically on the CK BB (as I've never noticed this on others) is longer, and it seemed to bottom out the threads before being flush with the adapter. But then I thought it was bringing my chainline out just a hair, and my front shifting wasn't that great anyway, so I took it apart and removed the spacer. Frankly, from what I can tell, it doesn't seem to make a lick of difference whether the spacer is there or not. Maybe someone else can chime in and set us straight with a real answer with some real technical reasoning, but that was my experience.

    Same experience here. 12 El Rey w/ a King BB. Tried both. I had a ticking sound with the spacer. Solved by removing the spacer.

    I recently installed a SRAM PF30 BB and XO BB30 crankset on my new Zeus frame. First time for me with the system but it seems to have drag when spinning on the stand. Is this normal that some have experienced? I am starting to second guess my purchase and wonder how solid the bearings are. I heard a rumor King has developed a PF30 BB. If so I will probably be on board with that quickly. I have 2 Kings on my other bikes and they rock solid and so easy to service. Bike is not built yet so maybe it will feel different rolling. Sorry for the slight thread hijack, but it was somewhat related.

    I have the FSAPF30 and a X9 crank and it definitely dragged when you spun the crank. It loosened up over time, but I'm getting the King BB when it comes out in Q1 next year. The FSA BB is already rough.

    Phishin Paul - thats exactly what I installed on my Zeus as well. I had to put my cranks in the freezer and really put some beef down via rubber mallet to get them through the bearings. My initial reaction was identical to yours, I was even worried that I'd done some damage. The cranks wouldn't spin worth a darn on the stand but after about 10 miles, that all went away and they spin freely. Granted, I'd LOVE to have a CK bottom bracket, but I'll wait until these wear out first....

    Eber and Endo73, thanks for the replies. Makes me feel a whole lot better. I too had to really pound the rubber mallet to get them in. I kept thinking I am probably messing something up and will have to purchase another set. My King hubs were on backorder for 2 plus weeks so I still do not have my new rig built up. Killing me!!!!

    thanks

    If I ever have to get another crank I'm not getting the PF30...unless I find that the King PF30 BB works out. I just don't have that warm fuzzy feeling with the PF30 right now.

    Ventana's don't use a spacer on either side since it's 73mm, unless...?

    I'm waiting for a Chris King PF30 BB to become available from Aspire Velotech. I trust that'll last for years. King will come with adapters for 24mm axles, and I'm sure that will work great, but I like the thought of a 30mm axle better, and am looking at cranks. I think my current favorite is the e*thirteen TRS+ or TRS Race with a Renthal sprocket.

    I have a BB30 XX1 crankset and my Stumpjumper Carbon 29 Singlespeed frame I bought second hand and I didn't realize this upon purchase that it has a GXP adater in it. Are these easily removed?

    I am using a PF30 bearing set from C-Bear. It uses aluminium cups and top quality bearings filled with grease for offroad conditions. I have put a lot of miles into it in all weathers and it is silky smooth and silent. Quality piece of kit.

    I just installed the RWC PF30-HT2 BB in an El Cap. Very nice part. I really like how the two halves actually screw together to tension and clamp within the shell. No need for silly adapters. Bearings out where they are supposed to be. I'd been waiting for the King solution but when I saw they too were using chunks of plastic to adapr the PF30 to a 24mm spindle I went elsewhere.

    Just got the SRAM PF30 replaced with the Chris King PF30 (BB30 crankset so no need for adapters) on my Zeus and I literally gained one gear. I highly recommend the upgrade!

    It is on my list. I cannot wait but the SRAM is still alive for now. Saving my pennies right now for a dropper post. I have the threaded CK BB on other bike. Do you know if the grease tool works with the new PF30 or do they sell a different one?

    Ditto on that. Kirkland bike in WA built my bike for me- zero creaks from the BB.

    I have a FSA PF30 to a 24mm adapter for my Shimano Hallowtech II XT crank. My issue is that after two rides of replacing the bearings, they are full of sand again. I think is the cover the FSA has for the bearings, that is not a good system.

    I don't want to have to be taking the bearing out every month to clean them. You guys have any suggestions? I'm leaning towards the Praxis Works but do you have any suggestions on how to keep the bottom bracket bearings clean?

    Thank you

    What PF30 set up are people using

    I finally installed the praxis bottom bracket. What in the world was I waiting for? The difference in pedaling was as significant as going from a 2007 X5 to my '12 Ciclon. So yes, I could immediately tell the difference.

    I had been running a hope ceramic bearing BB with the SRAM PF30 adapter. Memorial Day weekend I noticed some creaking from the BB. Got back to camp and pulled it apart to find quite a bit of crunchiness in what I think was the non drive side bearing. Had my Comandante with me to finish riding the weekend, so no big deal.

    At home I popped the bearing out of the housing to flush it and see if I could get rid of the crunchy-ness. No problem, bearing ran as smooth as can be. However, pressing the bearing back into the housing (the metal piece that is knurled and actually sits outside the frame and is the thing you put the external BB tool too), the bearing now felt crunchy again. Pressed it in and out a couple of times...each time it was fine outside the housing, but felt crunchy inside the housing. I can only speculate that a misalignment, however slight, messed with things a bit.

    Anyway, I too looked at CK. But was really disappointed to see them using plastic as well. Thanks to this thread, I looked at the praxis works BB. While yes, it does use a full length plastic sleeve in PF30 applications, unlike the SRAM plastic cups...the plastic the praxis BB uses has nothing to do with alignment of the two bearings. Having the two bearing housings actually thread into each other using both an interference fit and a clamping/compressive load that the bearing housings place on the frame makes infinitely more sense than having bearing housings floating around in two separate pieces of plastic.

    Ride report on the Real World Cycling RWC PF30-HT2 BB. After over 50 miles of sloppy, messy singletrack I am pleased to report this bottom bracket is still smooth, grit free, and spins like buttah. No creaks, no issues, never gave it a second thought except to notice how smooth it was spinning. Highly recommend this all metal solution to the run 24mm spindle cranks on a PF30 frame
