We accept returns, please notify us within 14 days and ensure the item arrives back with us no later than 30 days after the order was received.

EU Customers – for orders under €150 (excluding shipping), VAT will be collected at checkout, but from 1st July 2026, due to new EU import regulations, there may also be a customs duty payable to the carrier. For orders over €150, all import fees will be payable to the carrier, with nothing collected at checkout.

USA Customers – import fees are now collected at checkout for all orders to the US, so there won’t be any surprise charges when your order arrives.

Any applicable fees will appear at checkout.

HELP SECTION

Chainring Count - the number of chainrings the bolts are designed to fit, this must be the same as the number of chainrings you are using.

Crank Type - Most cranks require the standard 5-bolt sets that consist of 5 bolts with backs that slot into the rear of the crank spider, there are also some less common cranks with 3 arms that require the 3-arm chainring bolts. Specialites T.A. 'Professionel 5 Vis' and Stronglight '49D' type cranks require special 50.4 BCD chainring bolts that are specific to these crank designs.

Mount Type - most bolts simply fix the chainring to the crank, but some cranks require bolts to fix one chainring to another.

Back Nut Length (Excluding Head) - the more chainrings your crank has the longer the bolts and nuts need to be. We exclude the head part from the measurement (the bit that often sits recessed in back of the chainring).

Warm and cozy for winter
Size: X-Small, Color: Black (002)/White
I. Love. These. Pants. I have them in three colors and I feel like I live in them during these midwest winters. They are cozy and comfy for around the house, but are totally cute enough to wear out and don't feel like typical sweat pants or pajamas like some joggers can. They are warm and snuggly inside, which I like, and have held up really well after several washes. I would say they run a little small, so consider sizing up unless you like a snugger fit. I am usually between an XS and Small and went with XS on my orders. They are slightly loose but not baggy. They also are not super long, mine hit me near the top of my ankle and I'm 5'4". It doesn't bother me, but I do find myself pulling them down at the ankle when I get out of the car or stand up from the couch, because they just seem a little high. For a comfy, warm, casual but stylish athletic type winter pant (exactly what I was after)... this is it.

They fit perfect and are super comfy
Size: Large, Color: (001) Black / / White
Very soft and comfy! They are not the thickest to wear during a brutal winter, but they are warm. These are true to size (as recommended by my Amazon account). I loved these pants so much that I got me two more. They look great!

High quality, good fit
Size: XX-Large, Color: (001) Black / / White
These fit perfectly, not super baggy and lose but definitely not tight. I have larger knees so sometimes tapered legs are too tight on my knees but these are perfect. Waistband is perfect. Thickness is not too hot or too cold. Soft and breathable.

UA finally got the Tall size right!
Size: Small Tall, Color: (001) Black / / White
I'm 5'7" and 130 pounds. This is second time I've bought joggers from UA, size Small Tall, and OMG I couldn't be happier! UA FINALLY(!) got the Tall size right with these...the first pair I ordered about two years ago were supposedly Tall but shrunk up as soon as I washed and dried them. I like them to hit my ankles and not everyone is 5'4". Flattering fit - these sit at my belly button (not too low not too high) and are fitted not bulky. Material is heavier weight, well made, deep pockets, and perfect for Fall & Winter. After washing and drying with no shrinkage, I ordered another pair while still on sale.
