    BB30 ok for clydesdale?

    I've got the itch to get another bike and noticed that a few of my choices(Cannondale CAADX & Diamondback Steilacoom RCX) come with a BB30. I tried doing a search in the clydesdale forum and did not come up with anything. The results from the rest of the forums seem to be mixed. Some reviews indicate that the BB30 will develop a creaking sound. Am I worrying too much?

    Bb30 has a larger spindle then standard 24mm to stiffer in the crank is better. Most frames are laid up with more carbon or alum around the bb30 bearings in the frame. Win win if you ask me. I know I felt the difference in off the saddle performance when I switched.

    I ride a BB30 for the past 3-months & 2000 miles. No problems so far. I've heard the creaking is just when it gets alittle loose.

    I have a BB30 Felt F4 and no probs so far. I honestly don't like the concept so much with the press fit bearings. I have Dura Ace cranks with the Wheels adapters fitted. Being a clyde, things wear out much quicker and so should be the case for BB30 and the creaking that develops as the bearing/frame interface develops some play. Praxxis makes a really good BB30 adapter for the Shimano size cranks and it's a fit mechanism that lends itself to a tight fit in the frame.

    As a side note, I see all this stiffness increase claims with carbon cranks and big ouboard bearings and press fit bearings comical. I ride track where stiffness is king, and carbon cranks are rarely seen and regarded as flexy, and certainly not used by big sprinters (at least nothing for the regular folk). And with all the bottom bracket developments, the best track frames in the world still use in board scew in style bearings.

    Thanks for the feedback guys. That's one less thing for me to worry about.

    This thread hasn't seen much action lately. So I've started to hear creaking on my Felt Z5. Just search Youtube and you'll see how bad BB30 could creak. Mine is not that bad yet but every other day bothering me more. I will have it serviced this weekend. Let's see.

    Looking at the postings on other threads though it seems like BB30 gets a 50-50 review. Some say their creaking started just after couple hundred miles, and some say they had no issues after thousands of miles. I'm around 1300-1400 mile range on mine. I rarely pedal out of saddle on climbs, I don't sprint at all. It's just a 240lbs Clydesdale pedaling.

    Perhaps this is due to it being two years old. Bottom bracket style generally is not a make it or break it part of bike choice. BB30 do tend to creak but then so do other types.

    you have to service the BB30 just like you would replace the shimano outboard BB setup. Bearing parts cost is about the same, the tools to service the BB30 yourself are kinda pricey or equal to the shop doing the work for you. I have the LBS do the pressfit bearing stuff, they have all the correct greases that won't add to me DIY cost.

    http://www.amazon.com/Park-Tool-Bear.../dp/B00426ENBU

    Other places that causes creaks that may resonate through the frame that can fool you into thinking its the BB30
    ~Bear cups of the head tube. Carbon bikes has the bearing cups built into the mold, grease them and the bearings, especially after riding in rain
    ~Wheel drop outs and hubs. Put a decent amount of grease on the ends of the axle on both hubs. Also snug down the quick release skewer @TrojanHorse learned this one

    The BB30 in my Specialized Roubaix creaked. One thing I don't miss about that bike.

    Nope, I carefully selected my last bike so that it had a regular ol' english threaded BB and although other things have creaked (see jsigone's comment below), the BB has been rock solid.

    I'm with you. One BB30 bike was enough for me, for my current bike I've gone back to good old English threaded.

    Rebuilding the bottom bracket three times so far in 18 months is getting a little boring. My most recent rebuild so far has lasted 2000 miles, but I noticed on my last ride the dreaded "click" might be back.

    Frankly, all my bikes have the english threaded BB (so 4 for me, 4 for the wife & kids) and all the parts are largely interchangeable. I have spare cranks laying around... I know you can use adapters but simplicity is a positive force in bike maintenance.

    From all the reading around I have done over time, when you can actually get people to divulge the full facts around installation etc, the BB30 creak eventuates form incorrect installation. There's plenty of mechanics that still don't seem to know how to install them correctly or just take shortcuts. As stated before, I'm a clyde and I like to ride fast and I sprint. My BB30 frame is coming up to 3 years old now, still on the original BB bearings and adapter cups and no creaking at all. My LBS mech is an eccentric individual, but he makes sure he does a damn fine job.

    I'm also enjoying the silence of my English thread BB's after selling my last creaky BB30 bike.

    I read somewhere that Praxis makes some system to kill the creak on BB30's.

    BB30: if it creaks "you're doing it wrong". The ultimate put down that allows no sensible conversation to be had on the deficiencies of this system.

    It's a minor complaint on an otherwise outstanding bike. Before you test ride the bike, make sure they have the front DR really dialed in. Might be worth it to add a chain catcher. I dropped my chain inside my chainrings on my test ride on my Roubaix. That should have been a heads up for me to look at another bike, but I assumed the front DR wasn't dialed in. I had the bike in the shop a number of times getting the front and rear DR's dialed in. They went so far as to redo the cables on mine and add a tandem housing at the rear DR in an effort to get it shifting well.

    After all of that, I went on to drop the chain several other times over the life of the bike when I was really putting power to the pedals. The creak and chain dropping kind of went hand in hand. Usually it happened going up big hills and during longer rides, but a couple of times when I was pushing for a new PR, I would drop the chain on the flats as well. It really scratched up the carbon around the BB. Keep an eye out for that when you get yours. Mine may have been an anomaly as I don't hear others mentioning that with their Roubaixs. That was with 105 10-speed 5700 groupset with an FSA Gossamer crank by the way. The Ultegra 6800 might not have that issue.

    By comparison, I haven't dropped a chain on any of my steel bikes, nor have I heard a creak in the BB. My 5 year old SRAM Rival/Force groupset shifts smoother than any Shimano stuff I've ridden. That's what prompted me to get Force22 on my new bike.

    Just commissioned another build, and had the discussions with the builders, local mech buddy and several others. They confirmed my gut -- BB30 is not necessarily stiffer, if the crankset is stiff and the BB area is built with your strength in mind. They also generally don't like the interface in terms of installation. My gut is that anything requiring a hammer is not something I want to do with an expensive frame, especially if it's carbon and/or custom.

    On my steal roadie, I used to think I wanted BB30 on the next bike because I could feel some flex. Then I went with a stuffer crankset and the flex disappeared.

    The experience with the Roubaix described above with a dropping chain -- 105 is solid, BB30 is fine...my gut is it's the FSA chainrings flexing.

    As for me, I'm still riding English BBs. I'm 215 down from 260, and plenty strong. No issues, ever. Would I let BB30 stop me from buying a bike? Not really. But I would choose an English BB over it.

    I loved that bike -- just sold it last month.

    Rode a good 10,000 miles on it. Very smooth, got me back into steel. Slack angles were ideal for me at that point, as for a road bike its handling was very benign, and so a good re-entry into road riding after years away. And a very plush ride and clearance made it good for dirt roads, too.

    Hardly ridden after I got my IR custom bike made, which is much quicker in geometry and fits me perfectly (as custom will tend to do). Given that and a new bike on the way, was time to thin out a little. But, yeah, the Kapu was fantastic at the time -- great value, great ride, did very well by me. Sold to a nice guy on the other coast who had one but gave it to his dad. So, good karma on top of it all.

    I have a Felt Z5 and after a few hundred miles I had a creak develop in the bottom bracket area. I thought it was the BB30. I took it apart, cleaned, lubed and reassembled many times. It seemed to cure the creak for a ride or 2. After much frustration my LBS figured out it was the FSA Omega crankset and not the BB30. The spindle was loose where it was pressed into the drive side crank arm. FSA replaced it was an upgraded Gossamer model and now I have had zero creaks in over 1000 miles. If you have the FSA Omega crankset I suggest you take it apart and carefully clamp it in a vice. With mine you could gently rock the spindle back and forth and hear the creak.
