Mojoman Posted August 9, 2021 Share Heard a new creaking sound on the bike...got home...had a look in the light with a torch...And the crack is on both sides.... I dont think this is just the paint as if you run your nail over it, it feels quite deep... Any other opinions....Bike is a 2018 AL129...4 years old in Sept this year.... Always something to take your money.... Link to comment Share on other sites More sharing options...
DIPSLICK Posted August 9, 2021 Share Very unlikely that you have a crack on both sides i think it’s the paint also a consistent crack through the welding like that , possible but very unlikely can be Ex rayed but I’m pretty sure it’s a paint crack, saying that it must have taken a knock of note Headshot 1 Link to comment Share on other sites More sharing options...
Mojoman Posted August 9, 2021 Share This frame was already a replacement frame back in 2017...When I bought it I noticed the clear coat was peeling off on the chainstay and seat stays so they warrantied the frame...Makes me pretty distrusting of the bike now though.

DIPSLICK Posted August 9, 2021 Share That paint looks very thick, normally when it’s that thick and hard bump will cause it the “crack” where the bike has chip marks is it as thick as it looks? Link to comment Share on other sites More sharing options...
Trashy Posted August 9, 2021 Share It's difficult to tell from a picture on a screen but my gut says that's a crack, especially if you're also hearing a creak. That's a tell-tale sign in an Alu frame. Check the join between the head and down tubes underneath as it's quite possible there is a crack there as well if this is indeed a crack.

Maybe chip away some of the paint with a pic-tool ... If the crack runs into the metal it may be visible. Cheaper than an x.ray. and if it is only in the paint layer it may repainted at some point in any case Link to comment Share on other sites More sharing options...
Barry Posted August 9, 2021 Share Take the seat post out and see if the crack goes through. Or put soap water on the crack and blast with compressed air on inside. stefmeister, Me rida my bicycle, Dieter ( ͡° ͜ʖ ͡°) and 7 others 8 2 Link to comment Share on other sites More sharing options...
Mojoman Posted August 9, 2021 Share Well, lets see what the manufacturer has to say...If they um and aah on this then I will sand out that area and see if its the paint of aluminium...I suppose thats the only way to tell and to feel safe......Otherwise the quest for a new frame begins.....That should be loads of laughs with a straight steerer fork....lol...

Could very well be....You cant really see in the pic but where the crack is, thats where the alumiumium comes to an apex....The length of aluminium is sort of triangular in shape if that makes any sense?

Jaco Greeff Posted August 9, 2021 Share Looking at where the "crack" starts and ends it looks funny, as it it should start in the welding toe. If you are willing to polish away the paint you can do a quick dye-penetrant test. If you in the Alberton/Germiston area let me know.

Turns out you need a new bike, helmet, shoes and bike rack... and a free tubeless upgrade. But don't stress, they'll give you a good deal on all the stuff you don't need. love2fly, RomP and Sid the Sloth 2 1 Link to comment Share on other sites More sharing options...
Danger Dassie Posted August 9, 2021 Share Would say that's a crack, slightly unusual fault line though. Given that it's both sides of the frame I'd rule out paint work. Don't do anything to the frame other than removing the seat post to inspect inside the tubing, as has been suggested. ChrisF and Hairy 2 Link to comment Share on other sites More sharing options...
MG22 Posted August 9, 2021 Share Had a Momsen AL429 with the same problem. Momsen alu frames are sub standard. I transferred all the parts and components onto a Scott frame. I could not even give the Momsen frame away (nevermind sell it). In the end i threw it into the rubbish bin.

Mojoman Posted August 9, 2021 Share Lol...hoping it doesnt play out that way but it did take some effort when the bike was brand new to get the frame replaced......(clear coat was already peeling)... Link to comment Share on other sites More sharing options...
