I feel a lot of enthusiasm about the AR1 in this forum one of the reasons for me to invest in the frame. However, I wan to share my so far experience with the frame. I plan to post as these issues hopefully gets solved, comments are of course welcome.
1. My rear wheel is rubbing the brake. I’ve loosened the brake as much as possible it doesn’t engage before maybe 1 cm from the handlebar. There is a huge clearance to the brake pads, however it still rubs a bit when standing in the pedals. I’m 76 kg on a 56 cm frame using brand new supposedly very stiff Mavic C40’s. I’ve don’t have at hand other 11-speed rear wheels but plan to try out such wheels to rule out the wheel component. Basically I think there is something wrong with the frame but how do I prove this to Felt. I of course bought the frame in an internet shop (no Danish dealers) so there is no LBS to go to.
2. The crank is making a lot of creaking noise and I mean a lot! Later I noticed that there was also a little play in the crank. It turns without excessive resistance. When unpacking the bearings I noticed that they went pretty far into the bottom bracket with light finger pressure. My theory is that the tolerance is to big. The bike is now back at the LBS that mounted them. The LBS think that it is the bearing that are defect. That might be but honestly, less than 100 km on them and why should they lead to extreme creaking. Now I’m waiting on week 2 for them to get the spares.
As mentioned comments, suggestions, similar experiences
1: I have this issue too and I think it comes down to the wheels. I get no rubbing when using my training wheels (Mavic Cosmic Elite) but when my race wheels are on (Reynolds Assault Tubs) I get some rub. I need to slacken the brakes off when using the race wheels to limit the amount of rub. I'd try some different wheels first before you go to Felt blaming the frame.
2: I'd suggest using some Loctite bearing retaining compound when fitting the bearings. It's well documented that this can eliminate the creeks associated with BB30 bearings. This would take up any slight tolerance issue with the fit of the bearings.
