Cannondale Creaking

[Nomadski]

I bought a Cannondale Synapse 105 Alloy 5 in the summer, and after 80 miles or so on it my pedal was screwed up inside the Gossamer FSA drive side crank.

So went to Evans Cycles and ordered a new crankset, this time their Shimano 105, which they fitted, along with a BB30 Shimano adapter bought off the net for about £25, plus some new pedals (standard flat ones).

Went for my first ride, about 6 miles in got some creaking noises from when I pedalled drive side.

So took into Evans, few days later got a call to pick up, rode about 2 miles and creaks started again.

Took back, picked up a second time, got home no creak! Went for a ride day later and about 5 miles in creaks came back.

Back to Evans who rang yesterday for pick up, and within 2 miles of leaving, got creaking.

Now the guy on the phone from Evans saying they havent got a clue what is causing the creak, and not a lot they can do about it?!!?

So I have a bike which is meant to be decent, which creaks and groans like my gran and I have absolutely no idea what to do about it.

Only creaks when I pedal, doesn't when I lift bike and spin crank. Seems to happen on drive side rather than other side.

Any advice?

similar problem with my allez - the sora crank seemed to creak whatever i did! - then suddenly just like it started the creak disappeared - still not to reappear 2 years and 2000 miles down the road!

Try taking the seastpost out cleaning the post and inside the tube then smear with clean grease before reassembling. My Scott needs this every few months or it starts creaking in time with peddalling.

Gave it a go but no change. Still happens when Im standing on pedals also so not on seat.

Did a youtube video of it, please excuse the dodgy cycle handling, I'm far from good with 2 hands on the bars, let alone 1 holding an iphone...

Pedals?

 

[Nomadski]

I haven't any spares to try, but I did start thinking it was them. They were new on when I got the crankset fitted but they haven't been looked at by Evans.

Think I need to take it up to them to try different set.

If it was the adapter, do you think the creak would happen from both sides?

Try giving the pedal threads some grease. Had a similar issue. Didn't solve it but tighten your screws. So your seat post saddle etc. grease what u can

Sounds like the bottom bracket is either buggered or the threads haven't been greased.

The threads on the pedals? Funny two of you above saying same thing. What grease do you recommend? I heard on aluminum bikes anti-seize was better than grease?

Popping into Evans tomorrow, they said they will put on some spare test pedals I can ride on for a couple of hours and see if the creaking happens with different pedals.

Though if its a lack of grease, that wont solve anything.

 

[Rohloff_Brompton_Rider]

No I mean the bottom bracket threads, doesn't sound like a pedal issue to me.

 

[Rohloff_Brompton_Rider]

I just use cheapo grease, works fine on my bikes.

 

[Nomadski]

Hmm, will ask the Evans mechanic to check they are greased if the pedal change doesn't work.

 

[Rob3rt]

I didn't have speakers to hear the sound on the video, it was a general comment re. check the pedals as a possible source of creaking/clicking.

If the BB and crankset was fitted by a trained monkey they may not have put grease everywhere that's needed on the BB. I'm not familiar with Shimano stuff or BB30, but I know with my SRAM gxp that you need to apply grease to the threads, bearings (the seals are easily removable) and even one bit of the crank spindle. I had annoying creaks before I realised this. I use a lithium grease.

 

[Nomadski]

Feel like Ive got stuff to work with when I speak with them tomorrow, so appreciate the answers. I was under the impression Evans were better than Halfords, but now Im starting to wonder.

EDIT: Just reading here that BB30 and adapters are press fit so wouldn't have threads?

This is the adapter I use - RSP BB30 Adapter & Bearings For Shimano Chainsets
