Those heat shrink ends have been in my cart for some time. I hope you give an update on these whenever.
I have been reducing my Amazon usage of late and only resort to them in case of urgency. The “free” delivery is a total bs gimmick IMO but their return policy is a winner. The LBS is even below Amazon. For one they aren’t keen to talk about Chinese frames and wash their hands off immediately. My LBS has chains and few other things with REI labels still on them. Why on earth would I go there when I can simply buy them from REI, collect points and be able to nice people not trying to upsell.
My last draw was when mechanic at LBS told me my shifts aren’t smooth because SRAM chain was on it with Shimano cassette and they were incompatible, so I should get a new chain. The real problem? Too short of a chain, creating lot of unnecessary tension on RD. REI folks diagnosed that in minutes and gave me extra links to be added and that solved it. I understand LBS are under a lot of pressure but fooling customers with misdiagnosis is where I draw the line and we haven’t even talked about prices which is whole another can of worms.
