This Sigma Sports Cyber Monday discount code could create some of the best deals of the whole Black Friday sales event
There are some brilliant Cyber Monday deals here on Shimano, Assos, and Specialized
It's Cyber Monday today, which means the conclusion of the Black Friday sales event, which has been running all weekend.
There have been loads of deals, some average, some good, and some pretty great. Our focus is on bringing you the best ones we can find, and peppering them into our Cyber Monday bike deals roundups.
Most deals from Friday stay the same until today, and elsewhere, plenty of new ones are released. This is the case at Sigma Sports, which has released a new EXTRA20 Cyber Monday 20% off discount code that can be used on selected and - crucially - already discounted items.
Head straight there to see what's included.
We have applied it to a few deals, and it just may result in some of the biggest deals of the whole weekend. We have found some monster savings.
To take advantage, add your chosen item to your basket and add EXTRA20 in the discount code box to see the new, lower total. Not every item is included, but there are over 4000 to browse in the 'Extra 20' section.
Take a look at a few we've found below; there are some genuinely good deals here.

Tom joined the Cyclingnews team in late 2022 as a tech writer. Despite having a degree in English Literature he has spent his entire working life in the cycling industry in one form or another. He has over 10 years of experience as a qualified mechanic, with the last five years before joining Cyclingnews being spent running an independent workshop. This means he is just as happy tinkering away in the garage as he is out on the road bike, and he isn’t afraid to pull a bike apart or get hands-on with it when testing to really see what it’s made of.
He has ridden and raced bikes from an early age up to a national level on the road and track, and has ridden and competed in most disciplines. He has a keen eye for pro-team tech and enjoys spotting new or interesting components in the wild. During his time at Cyclingnews, Tom has already interviewed some of the sport's biggest names including Mathieu van der Poel, Tadej Pogačar and Alberto Contador. He's also covered various launches from brands such as Pinarello, Ridley, Specialized and more, tackled the Roubaix Challenge sportive aboard his own rim-brake Cannondale SuperSix Evo, tested over 20 aero helmets in the wind tunnel, and has created helpful in-depth buying advice relating to countless categories from torque wrenches to winter clothing.
