HELP SECTION

Chainring Count - the number of chainrings the crank was designed to fit. Fixed gear track bikes, single-speeds and some geared bikes use a single chainring, road bikes commonly use a double (two rings) and most touring bikes and mountain bikes will use a triple chainset (three rings).

BCD - stands for Bolt Circle Diameter (sometimes referred to as PCD - Pitch Circle Diameter), and this needs to match the BCD of your chainring(s). To calculate this, measure the distance in millimeters from the centre of any chainring bolt hole to the centre of an adjacent one and multiply it by 1.709 (you’ll likely need to round the resulting number up or down a little to get your BCD measurement).

Crank Arm Length - this is measured from the absolute centre of the bottom bracket hole to the centre of the hole for the pedal.

Pedal Threads - the pattern of the thread that your pedals screw into, this is usually stamped on the pedals themselves and most bikes use a standard thread of 9/16” x 20 tpi. The exceptions being older French bikes, bikes with cheaper one-piece type chainsets and Shimano’s Dyna Drive system (easily identifiable as the pedal holes are about an inch wide!).

Bottom Bracket Type - ‘square taper’, as the name suggests have a square shaped axle that slots into the crank and ‘cottered’ axles are round and secured by pins - pretty much every bike up until the 1990s would use one of these, cottered being the much earlier system. Since then, different manufacturers have introduced their own systems that are not interchangeable so you must use a crank that matches.

Simple and hassle free claims process
I have had to use my insurance policy for several items and the process was simple and hassle free. I mainly purchased this policy / subscription because of one very expensive item I bought with a likelihood off electronic or mechanical malfunction at some point and wanted it covered but I have used it for several other lower priced items that had failed on me. This type of policy would be great for household who purchases a lot of electronics which really isn't me. But The process almost couldn't be easier.

In this age of planned obsolescence, definitely a life saver
This is not my first claim since subscribing, I have had multiple things break, and Asurion complete protect is great. It is cheaper than buying protection plans for each individual item. I love it. Quickly head over to the website and then start a claim and then they take care of the rest with awesome communications.

Fast and easy but I dont trust the process to be fully automated.
The process was very smooth and fairly quick. The only challenge I had was that the CLAIM status showed complete but I had to manually go look up the status. There was no email or notification it was closed. After manually checking the status, I called customer support and they said since I called in, they would process the payout. I wonder if I didnt call in if they would have processed it? Also, the phone rep said they would issue me a amazon egift card but then the next day I received a email saying they mailed out the payout. Very poor communication but so far the process was easy and fast.

Dog lovee it
Flavor Name: Bacon - Kit
My pup loves the bacon flavored toothpaste. Can't say I blame him. I almost want to try it myself it smells so good..... Come on man!!! it's bacon flavored!! Someone should make this for humans. Haha. I'm just kidding around folks. My dog is very at ease when I brush his teeth now since he loves the bacon flavor and its really helping with his oral health. The finger toothbrush is easy to use and effective. Soft on pups gums and easy to clean. Great product in my opinion.
