Probably will not get my money back but I learnt a thing or two. First off, don’t judge people by their look. I business man lookalike that acts busy might just be the worst dishonest seller ever.
So basically I was shopping for a pair of used GP5000 to test out, and I found this seller selling his wheelset with a pair of 28c GP5000. This is pretty damn great, DT wheels with GP5000 what could possible goes wrong right?
After transferring him the money, I spent the evening finding and swapping some cassettes and rotors around from my mountain bike stash and manage to get a ultegra cassette 11-28t cassette and a pair of shimano rt-99 rotor. All is well until I mount it on my Aspero to do a spin test and lo and behold, it seized after clamping!
It does not make sense to me, all the clearance are checked, no rotor rubs but why isn’t the wheel moving? So attempt to contact the seller and he started giving excuses and what not then he ignored me when I attempt to get his details. Long story short, the guy is probably ignorant or is a fraud. Not wanting to waste anymore time I decided to just log a police report later when I am free. Also he keep asking me to go to a shop called Bike Labz and said that the wheels are removed and tested by them and I should get them to install on my bike.
Lol… Sure as hell I am not going to let a bike shop that cannot identify a wheel with a bad bearing to service my bike.
While attempting to figure out what is wrong with the hub, I went ahead and dismantle the hub, then I realized that the hub is not a DT hub but a Formula. Basically this wheel is made up with a low cost dt swiss rim and low cost hub/spoke, I highly double it is worth SGD$350 even with cost price. The 2 hub probably cost around $110 and $100 for both rim plus another $40-$50 for spokes and nipples.
Anyway, after breaking a part the hub and left only the 2 main bearing and the main axle, I fix back the cones and try mounting it on the bike, still seize. This meant that the freehub/rachet is not the issue. I give the main axle a little shake, sure enough, there is a little play. Seems like the bearing had been push out of place and the thru axle clamp basically gives too much preload pressure, one of the bearing also feels a little gritty, probably had some bad balls within it.
There is a high chance that maybe one of the washer was lost or the wheel was hit on the axle when dismounted. I ordered a couple of spare 6903 bearings and will probably replace them once they are here.
