Bottom bracket on my Cannondale Synapse has broken.
Specific bike and spec is here:
Was ticking / clicking (worse than normal) for a short while beforehand (week or so) and I stupidly ignored this. Then it started to squeal and squeak extremely loudly mid-ride the other day. I lubricated with the only oil I had (3-in-1 oil … yeh I know !!) and it seemed ok for a short while but yesterday I tried some outdoor sprint intervals. Midway through the 2nd interval I heard a horrible crunching / creaking noise and it felt like it was ‘loose’ - it’s the only word I can come up with to describe the sensation through my feet. I did the rest of the ride (circa 20 miles loop home) at a slow easy pace and the pedalling felt ok-ish but with some squealing and creaking noises. On tentatively trying out any harder effort the noise and sensation reoccurred.
So I think I clearly need to replace / fix the BB
Normally this would be a trip to my LBS (who re-greased and tightened it all up about 2 years ago when they fitted by Stages crank power meter) but they are closed and are only undertaking repairs via phone booking - a quick call to ask revealed they are now over a month away in terms of now only taking bookings for late May
So I have decided to get stuck in and do the job myself …
My questions are:
- What tools do I need - the LBS said because Cannondale used the FSA BB30 bottom bracket I need a ‘special’ tool to remove it. I’m UK based so does anyone have a link to an on line place it can be obtained? I have a torque wrench and other ‘basic’ tools. Do I need a special tool for the bearings?
NB: I have decided I want to replace the entire thing rather than just some elements, as to me it makes sense to start again with a ‘clean plate’ so to speak, in case any part that may ‘look’ to be still ok is in fact nearly worn out.
What other bits and bobs do I need to order to replace all the gubbins internally - plus is there a sensible ‘upgrade’ option I should reasonably consider whilst I’ve got the whole lot in pieces. What grease / replacement parts do people recommend?
Can anyone recommend a good easy to follow on line tutorial for this type of job. I’m not bad at mechanical stuff once I’ve been shown what to do a couple of times - but I really have no idea where to begin at this stage.
Hoping to be able to get some on-line ordering done and have the bike back up and running next week -dependant on delivery times …
Thanks in advance
