HELP SECTION

Chainring Count - the number of chainrings on the chainset. 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).

Tooth count - the number of teeth on the chainring(s), the higher the number the harder the gear.

Chain width - this is only relevant for chainsets with a single chainring - if this is ⅛” then you must use a ⅛” chain. All double and triple (and some single) ring chainsets will use a standard 3/32” chain.

BCD - stands for Bolt Circle Diameter (sometimes referred to as PCD - Pitch Circle Diameter) and is only really needed when changing chainrings. To calculate the BCD, measure the distance in millimeters from the centre of any chainring bolt 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).

*Intended speed - the number of cogs at the back the chainset was designed to be used with. We refer to it as ‘intended’ speed as most double and triple chainsets will actually work with different speeds than originally intended, but the further away you get from the intended speed the more likely you are to experience minor setup issues. The exception being some chainsets intended for 10 speed use or higher, with these it’s better to stick to the intended speed.

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 thread type to match that of the chainset, this must match and 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 chainset 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 chainset that matches.

Beautiful and sleek black hobo bag!
Color: Black, Size: One Size, Color: Black, Size: One Size
This purse is absolutely lovely for the price! Such a cute hobo bag, yet is modern and sleek to make any outfit look polished. It is super soft and has a faux leather texture with a beautiful sheen to it. It seems like great quality and if it ever gets saggy or old, it's cheap enough to replace easily. I love the gold hardware and it also has a lovely gold metal label of the brand on the outside making it look expensive. Also the strap is thick enough that it is quite comfortable on the shoulder. The only gripe I have is that it looked a bit bigger online, it fits about as much as a tote bag would; also the pockets inside are a bit small, but overall, I LOVE it!

So spacious, great school bag
Color: Black, Size: One Size
I love this bag! I was looking for a bag that would hold my laptop without looking like a school bag, and this is perfect for the job. It fits my MacBook, granted it’s a tight fit with the case on, and it’s like a bottomless pit. I lose things in there so often, it’s so big. I’ve been using it for months now and it’s showing pretty much no signs of wear, and it’s pretty lightweight until I put my school things in it. It has two pockets on the interior, one open one on the side and one that zips up on the other side. The one that zips holds a decent bit. I held a ton of makeup in it before I decided I needed something better and that I was making it poke out too much. I don’t use the other side as much. I hold a couple of things in it, but nothing that can easily slip out. Ultimately, this bag is sleek and easy to carry around, it’s also not uncomfortable to wear when holding heavy things. I feel like skinny straps always dig into my arm, but this one is comfy. I liked it so much that I got another one in red as well. Overall, it’s a great bag and I recommend it to anyone who needs a Mary Poppins bag to hold a lot of things.

spacious, pretty and super sturdy!!
Color: Burgundy, Size: Large
soooo nice I’m obsessed! I treat my purses like black holes but I wanted something I could customize to my liking and it’s big enough I added a bunch of small bags inside to separate things and it’s still so spacious, and the wine color is my fave this season

Love it
Color: Cream, Size: Large
I love this purse, not too big and not too small. I love the soft leather and also because I can use it when I dress up and or dress down, looks good either way. And the makeup purse is a great addition to help keep all my things together. Love it
