Scott Spark 29 Elite Frame cracked 2 times

[milky4130]

Where did it crack? Also have the 29 Elite and LBS was told by Scott to make sure that bottom pivot point (near the crank) needs to be well maintained (lots of WD40 after washing). Said that if it isn't, the bearing seizes and the frame will crack.

the last time I sprayed wd40 into bearings then only did the bearings cease up, I think the grease must've dried up shortly after that.

I have been riding my bike in the rain reguarly ,and also been washing my bike.The problem is you end up washing the lube out.I replaced my main pivot bearings 6 months ago, but was supprised to find last week the one bearings inner race was seized onto the pivot when I checked it last Saturday.I have fixed it but have decieded every three months or so I will have to remove and lube the pivot and check the bearings.

Hi all,

Unfortunately we cannot change what has happenned in the past however I can assure you that we have taken note of these issues and have raised them with Scott International.

 

As Scott Sports Africa we are in the process of improving our stock holding of both loan units and replacement parts so that we can improve our warranty turnaround time or at least keep people on their bikes should a replacement part not be immediately available.

Momsen local... dont think so! went to LBS and asked about getting a momsen the reply was they waiting for a shipment in from Taiwan!!! maybe designed local. has anyone here been to the SA Momsen factory were the make the frames and assemble?

 

 

When I say they are local its more along the lines of the principle members being local and literally a phonecall away. For me TWO wheels trading is local as myself and them are in Port Elizabeth. Not disputing that the manufacturing, along with virtually any other brand, is done in the East.

 

I have a Momsen warranty replacement frame (Al twen9) the new frame is busy cracking in the same place. I put it down to mass production and no quality control, but, I'm no expert.

 

There goes my belief that they have hed zero failures.

Please share a bit more detail, where the failure was, etc. These Scott failures are bearing related which is mainly on DS bikes it seems, common HT failure would be seattube and could be as a result of the seatpost not being in deep enough.

If you look closely at the Momsen 929 and the Sentesi Flu they are the same frame except the Momsen has the PYGA drop out which is terrible on the Momsen(works well on the PYGA), as all it takes is a light bump on the derailleur and it moves messing up the gears. They are both just re branding some Chinese frame, which I suppose they are allowed to make some modifications on if they order a whole bunch of them.

Thats exactly where it's cracking. My seat post is in pretty deep. Any way it does not really affect much it's just not cool knowing your frame is cracked. Other than that it's a awesome frame and Momsen was super quick with replacing the previous one.

Here's a broken Momsen HT frame, photo was originally posted by someone on the Momsen Facebook page. It's not there anymore funnily enough:

 

 

Also cracked carbon Momsens mentioned here: http://www.thehubsa....n-sl729-r-type/

I am sure that if consumers were told this prior to purchasing the bike, they would look at other brands where there aren't design flaws.

The thing is the same design exists in the various top brands:

Scott Spark

Specialised Epic

Trek Superfly

Cannonadale Scalpel.

the issue comes down to the quality of the bearing and how well it is protected.

regular regreasing will help replacing what is washed away and regular checks on these bearings will help reduce the strain the frame gets placed under if they seize. Remember these bearings only turn maybe 5%, its not like a wheel bearing that does revolutions and can stay loose longer. The pivots only turn a tiny amount as the rear triangle flexes over terrain, thus the bearings only do a miniscule ammount of work. If they take on water, it festers, they rust, and they seize.

Good.

I would regrease more often though.

the last time I sprayed wd40 into bearings then only did the bearings cease up, I think the grease must've dried up shortly after that.

Some lubricant oil sprays can actually dissolve the grease within the bearing.

Once water has entered a sealed cartridge bearing it will never get out. it mixes with the grease and forms emulsion and if standing, will start oxidising the ball inside the bearings. Seizure happens soon after.

This is why i will never buy a scott. Anthems break, but giant is very good at replaceing.

To be honest, Scott have been quite on the ball when it comes to replacing parts in my experience so far. (Twinlock, derailure hanger, rear pivot chainstay)

I dont believe there is one bike that lasts longer than another, ALL have varying issues and problems. It is a machine that gets drilled over rough terrain, so we cannot expect whatever bike we ride to be unbreakable - unless you are driving miss daisy.

[Li Mu Bai]

Fully agree with you on the statement above, however there are specific models that are more prone to failure than would be considered normal that have been reported on this forum.

i.e: Giant anthem series, Scott 29erDS series, Silverback Vida HT series. These are the few I can recall off hand that come up quite often.

Brands I have not heard of problems from are Santa Cruz, Merida, Momsen, etc.

So you can make a calculated choice when looking at which are more prone to failure.

You're fortunate in that you have a one of a kind, never experienced any failure whatsoever, brand............

Just for the record I ride Aluminium as I do believe the carbon is more susceptible to failure.

Rubbish. The aluminium rear chainstay cracked and broke before anything on my carbon front triangle (which is still rock solid).

I have also had welds fail on previous aluminium frames I have ridden, so the idea that Aluminium is superior to carbon is a myth...

how do you maintain the bearings then? The WD40 advice came from the mechanic at the LBS who claims it was told to him by the Scott Rep...

WD40 is only good for seized parts, not for bearing lubrication.

It also useful to blast out old grease in a bearing as well!

[Li Mu Bai]

maintain cartridge bearings? you replace them

Dissolved... by the WD40.... blame yourself please.

 

Personally I always service new bearings before installing them - especially suspension bearings - the more grease the better. I don't believe they come ex factory completely filled - and for a suspension bearing completely filled is best.

 

And that applies to a new out the box bike too - strip, clean and re-grease bearings - replace them if they are rough.
