"Ordered parts February 23rd. Received a confirmation email same day. Never received the parts, never received another email, cannot leave a voice message, and has never returned my emails. It’s now August 30th. Basically stole $133.00 from me. Just send me my money back if you aren’t sending me the part. What is going on?"

"Multiple emails sent and not one response from this so called company. Had to do a charge back with my CC company. Many years ago this was a great company, not so much anymore! Buyer beware !"

"Rarely answer their phone. Do not return messages. Terrible order tracking and organization. They overlooked my order. Gave me wrong tracking info and have the terrible communication. Has to be a 1 person show with index card invoice system at best. Just returning a voicemail would be such a courtesy this business has none! Performance Cycles Of Wilmington inc"

"I purchased the M6 BT07 from a different vendor instead of directly through Hayden. Unfortunately this vendor sent the old stock springs which were out of specs and made the chain way too tight. (In the mean time I tapped a thread and bolted the stock tensioner together to make it into a manual adjuster to be able to ride.) These folks would not provide the newer springs but after contacting Hayden they did so free of charge, even knowing I didn't buy the M6 from them. Just installed the M6 with the newer, shorter springs and now my bike runs so much better and with smoother shifting. Supposedly there is a temporary noise while the chain seats in the shoe but it's hardly noticeable on my bike. Others have said they have had problems with Hayden not returning messages, and I had that experience as well, but only when emailing them. After calling their phone number they returned my call a few days later. Very happy with the M6 and the Company. Matt, San Diego"

"5 star service. I ordered my tensioner and I needed it fast as I was going on a long trip. I sent them an email and asked them how long would it take to ship to the uk. They shipped it to England and I received it in five working days. Great company Thanks"
