Ace groupset

I bought this Ultegra R8000 groupset to upgrade from the 5800 one that was on my bike at purchase. I think it’ll give me the improvement I’m looking for as well as re-vitalising my R2 climbing machine. It came at the best online price... great PBK value and fast delivery service! Thanks


Nothing that's not been said before I suspect but the quality and performance of Ultegra is unbeatable for the money. I switched from a mish mash of components with a 105 cassette that was ok but the full Ultegra groupset is in a different league. I don't understand some reviews that say they can't feel a difference. Oh well. One word of caution. Just when you think you've looked at everything, I had to buy another front mech as the one supplied was braze on and I didn't check....

Shimano Groupset R8000

Excellent in Customer service, knowledgeable with any bike related questions I asked from sizes to heights. I couldn’t ask for more. I got the perfect group set that I wanted. Keep up the good work 🇬🇧. I salute you for your patience and commitment in what you do

Best Performance/$

Replaced my Dura Ace 7800 10 spd groupo (arguably the best 10 spd Shimano every made, i.e. better than 7900) with Ultegra R8000 - wow! So nice. Mad my 10 year old Cervelo R3 SL feel like a new bike - better brakes (very easy to align pads + dual pivot = stronger, more consistent braking). New designs for both derailleurs makes them way more precise to setup and again - shifting is precise and consistent. Buying this groupo and my new Dura Ace R9100 C40 CL saved me about 10 grand - I almost bought a new super bike. Instead, I rejuvenated my current super bike (and save hours of position set up, etc. - lol). Very happy with this purchase and with ProBike's service (and price!). Also, ProbikeKit ships the bottom bracket and cables (not shown) with the groupo - everything you need to upgrade your groupo.

As good as Di2!

Bought this for a travel bike I’ve built. Was prepared to be disappointed returning to mechanical shifting. What a great surprise to find it’s as positive and exact shifting as my electronic Di2 race bike. The only difference is the amount of throw required at the lever. Great group!!! Way improved!! Fantastic price point.

Shimano Ultegra R8000 Groupset

As usual a very high standard of components from shimano, im building a new machine with this ultegra r8000 set, a two-tone black/dark grey adorns all the parts, Crank spider & arms a half polished black finish looks amazing. Carbon levers with a quicker gear response & ribbed hoods are an move up from the older 6800 version, even the cassette has 1 carbon spider great service from ProBikeKit!

Ultregra is good

These produc is perfect for people who don’t have the income to get dura ace. This product compares to dura ace, only that Dura ace is a little bit lighter.
