If you’ve been waiting for the right moment to upgrade your road bike drivetrain, this could be one of the standout deals of the season.
Shimano’s Ultegra R8170 Di2 groupset can be had with up to 53% off, down from its RRP of £2,399 to as low as £1,091.59, depending on the setup.
That’s serious money off one of the most desirable performance groupsets on the market.
The deals can be yours from Merlin Cycles and Sigma Sports, with the latter offering the low price of £1,091.59 for a 175mm cranked 52/36t chain-ringed variant.
If you want more choice in crank length, cassette and chainring size, then Merlin Cycles appears to offer all sizes available for £1,125.
Sigma Sports also has similar options available priced at £1,149.

Positioned just below Shimano’s flagship Dura-Ace range, Ultegra Di2 delivers much of the same fast, precise shifting and refined braking performance — without the eye-watering top-tier price tag.
When we tested Ultegra Di2, we praised the groupset for its crisp shifting, dependable braking and overall ride quality, questioning whether many riders would genuinely benefit from spending more on Dura-Ace.
At this price, if you’re looking to upgrade your bike's groupset, this could be a no-brainer.
