Short version: I bought a Specialized bike through SigmaSports (and they forgot to grease the seatpost that got it completely stuck in the frame). SigmaSports decided not to believe me nor try to help me (I live in Germany, they offered some possible discount on a new frame) and said no warranty claim could be triggered. I then contacted Specialized in Germany and they performed an inspection and confirmed SigmaSports did a mistake and I got a new bike through them to replace my faulty bike from SigmaSports. Long version: Late 2018 I bought a Specialized Crux cyclocross bike through SigmaSports. Sadly I used the bike very little in the first year and it was mainly sitting in my flat at room temperature (about 100 km ridden according to strava). However I wanted to try and ride more during autum / winter and at the end of 2019 I took the ride out for a spin only to realize that the seat post was completely stuck. After trying all the tricks I had found on youtube I took the bike to two different bike shops and they could simply not move the seat post at all, where their hypothesis was that sigmasports had not applied any grease / fat to the seat post from the beginning - seeing the bike looked almost brand new. I contacted sigmasports and they simply told me forget about any possible warranty claim and they could "maybe out of goodwill give me a small discount on a new frame". After some back and forth with sigmasports customer service they state that I could maybe ship the frame to the UK and they will try and get the seat post unstuck but this will 100% not be covered under warranty. Instead of making the effort to ship the bike to the UK and all the costs this would include I decided to contact Specialized Germany. They eventually helped me out, performed an inspection and confirmed that sigmasports did not apply any fat nor grease to the seat post from the start (as written above, sigmasports did not believe me even though I had taken the frame to two different bike shops). This obivously triggered a warranty claim and last week I got a brand new Specialized Crux delivered to from Specialized Germany to replace the faulty bike I got from SigmaSports. Specialized Germany showcased excellent customer service, whereas sigmasports were arrogant and refused to even consider that they might have made a mistake and I would advise anyone buying a new bike to reconsider due to this reason. I wrote to Sigmasports a week ago informing them that I would be writing a review about my experience and they did not get back to me.
