I wish Cannondale would ditch bb30 for HT2 in 2015

Serious Cat

Imo bb30 is a seriously inept design that firstly wasn't required and introduced problems instead of offerring improvements compared to hollowtech 2 which just simply works a charm and doesn't come with bb30 creaking soundtrack and bearing problems thank goodness. Unfortunately cannondales from tiagra up have that bloody bb30 :x :x . BB standards have become such a mess,if bikemakers went to hollowtech 2 En masse then I think things would be so much better and bb30 would be quickly relegated as a bad idea.

Well, Cannondale were the ones who invented the crap BB30 so not likely they'll be changing to threaded BB's anytime soon.

How Far is too Far

3 bikes on BB30 no real problems apart from the odd strip and re grease. Easy to work on with no special tools required unlike a bike I have on Campag.

Press fit bottom brackets are here to stay - I do think the Shimano Press Fit system employed on Giants/Scott frames is better. Besides you can always use an adapter!

I have had more problems from square taper bottom brackets than I ever had because of BB30. But that is my limited experience.

I have ridden my BB30 bike in torrential downpours, freezing conditions and mountain passes. I think it is ok.

The OP is turning into a parody of himself.

Sorry but I think that's bollox and a google search re many disgruntled users will verify this. There are also a mountain of internet forum contributions ranging across the globe saying the bb30 is absolutely useless, fraught with issues and owners wishing they had never bought a bike with it ,also do youtube searches for bb30 creak and try not to weep. I expect your time to share in their frustrations will come eventually seeing as you obviously have a bike or bikes with it

I'm with Serious Cat on this one, I bought a Bianchi with a BB30 and after 15 months of bottom brackets issues I decided to sell it. I would never even dream of buying a bike again with a BB30 system or actually none of my friends would after hearing my old Bianchi creaking for 15months.

Yeah, found bb30 creaky as hell after wet weather which is going to be fairly often in the UK. Maybe not so good for wet weather countries due to the exposed bearings.

Focus Izalco, brilliant frame let down with a BB30 bottom bracket.
I wouldn't touch another frame with BB30, I never got a creak or a squeak from the BB but the water ingress was terrible and that was with Cruds fitted. One set of bearings lasted 400 miles during the winter so because of that I was forever taking the crank out, drying the BB shell out and re-greasing everything.

Where is the water getting in?

Monty Dog

Water gets in down the seatpost - but the fact that the bearings press directly into the shell means the bearings are immersed in dirty water, flushing out the grease and corroding in no time. Solutions are drilling a big hole in the BB shell and hanging the bike up and removing the post after a wet ride to let the water out. I have BB86/92 on a couple of my bikes - a CX and an MTB that last winter were frequently immersed over the BB but because of better sealing and because the bearings don't sit directly in the shell don't experience the same problems. FWIW Cannondale didn't 'invent' BB30, they bought Magic Motorcycle who did - but they were a precision engineering company, it simply wasn't designed for high-volume production which a further reason for the problems.

Serious Cat

Sale of Goods Act and not fit for the intended purpose. BB30 is a pile of junk with a host of different stories from unsatisfied customers. On the club run this morning I spoke to two different riders both riding bikes with BB30 bottom brackets and I asked did they ever get the creaking. Both said absolutely and their bikes just constantly need worked on to keep the creak at bay,in fact there is another club member who rides a new cannondale evo 105 which he purchased a few months ago and that thing is creaking like crazy, incidentally both riders I spoke to said HT2 is a much superior system requiring little to no maintenance for periods spanning years at a time. I wonder what chance litigation based upon bb30 simply not being fit for purpose would have in the courts in the UK ? Any lawyers here ?

The times I have checked the bottom bracket area, my Caad10 has always seemed pristine. I do tape up any seatpost potential water leakers... and yup, not often but yes my bike does get a wet ride even though I positively try to avoid the occurence.
Maybe , just maybe, pressfit, dont make the best practical choice for commuting purposes.. but reading a into a lot of forum contributions.. a lot of people who consider themselves serious cyclists are completely clueless about bikes. Its just inevitable that many inot cycling just want to ride and forget.. a bit like modern cars. I grew up in that generation that if you werent faffin about with whatever you were going to be lost, cold, wet, pissed off, late, .. and all phone boxes .. although never vandalized, were always 10 miles walk away...

letap73

BB30 biggest issue is that the bottom bracket shell has to be precision made to a high tolerance - this is not possible at the moment in mass production. Hence why certain people have real problems, while others are lucky to have shells made to tolerance or simply prepared to service the bottom bracket at regular intervals

The Shimano pressfit system does not have that problem and generally works very well. Not all press fit system are the same!

jgsi

Quite possibly.. all goes to making informed purchasing decisions.

There must be something wrong with the BB30 on my Synapse.
15 months old, and around 3000 miles, there isn't a squeak, creak, groan or cracking noise (used year round for communting)



Obviously, this is the kiss of death :shock:

In all seriousness I hope your Synapse doesn't start clickety clacking, I can replace a HT2 bottom bracket on my own, whilst blindfolded in a totally dark room in literally minutes. Just watch the shenanigans of this guy telling you how to replace a bb30 on his synapse whilst he needs a guy to hold a tool for him whilst he wallops it with a hammer and all those parts lying about on the freaking floor and imagine one got lost :shock: , jeez I really hope you wont have to have a go replacing a bb30 on your synapse any time soon mate , what a kerfuffle compared to doing same with HT2 ha ha ha ha , ah well there is always LBS guy to fall back on and hand over £40 to him after every wet ride and a new bearing replacement is needed if you don't have the skills to do it yourself

I've just installed the fsa sleeve thing that converts from bb30 to bsa.

I most certainly won't buy another bb30 bike again, too many noises and too difficult and fiddly to maintain.

My caad8 was my first decent bike and I didn't really know what I was getting with bb30.

Always do your research.

Not buying another bike with bb30 would appear to be the right way to go mate.

Square taper most durable BB?

10 year warranty on this on abit pricey though

Statistics is not really your strong suit, is it?

It appears all major bike companies working with Carbon are tending towards press fit bottom brackets so it not so easy to avoid them. HT2 utilises the Shimano press fit system - the Shimano press fit bottom brackets get good reviews and are cheap. I suspect BB30 will be replaced by PF BB30 which also has problems however, I suspect the SRAM PF30 bottom bracket is rather poor and a decent bottom bracket will start to solve the problem. Hope appear to have a good solution (two cups connected by a sleeve with a thread:

HI Sloppy disguise isn't your strongest suit either :roll: now how many other user I'd,s do you have ,kinda sad but I'd expect no less from you.

Tap there wasn't an issue that needed addressing, that's the point mate, HT 2 just works and if it ain't broken, oh btw trying to get others in bottom bracket to stir this could get you banned as velo and ugo are tiring of the kindergarten behaviour that is present at BR and those who stoke it, just sayin

It's a simple enough job to fit a FSA adapter tube with 24mm threads. Or use a Praxis Works converter.
I used Cannondale's own sleeve adapter on my Supersix so I could use shimano external bearings and crank.






My mountain bike has a cheap BB91 Shimano press fit BB which seems to be holding up OK. How do Shimano BB86 road bike bearings like this hold up ?

In answer to your question Adamfo very well - 3 to 4 times better than the SRAM PF30 BB bottom bracket as explained to me by the EPIC cycles tech. The Shimano press fit bottom bracket gets good reviews, the SRAM ones don't.

In fact my SRAM GXP bottom bracket is starting to go - which I think is poor for a threaded bottom bracket. SRAM bottom brackets don't seem very good.

MisterMuncher

Catch yerself on, Cat. It is possible more than one person to disagree with you. I don't even live in the same country, ye eejit.

My Felt Z4 has a BB30 BB. I have recently completed a 1000 mile Dover to Cape Wrath ride on it plus about 500 miles before that. The BB is totally silent. We only had one day of rain on the D-CW epic but it was heavy rain. I guess the biggest issue if you decide to change is having to buy a new chainset, i.e. one with a 24mm spindle. Changing to a different bearing system is the cheap bit.

1500 miles isn't really enough mileage to make any conclusion.
