It’s a pretty open secret that Shimano plans to release a new version of its top-end Dura-Ace groupset at some point this year, and thanks to a couple of leaked photos from the Taipei Cycle Show, we got a glimpse of what it might look like.

Now, they’re not the best photos in the world so it’s hard to say exactly what Shimano will change for 2017, but the rear derailleur looks to have a long cage and be modelled on the company’s XTR mountain bike rear derailleur, while we can rule out 12-speed and wireless shifting.

The new Trek Domane made its race debut in some style at Strade Bianche last Saturday with Fabian Cancellara taking the win on the new bike ahead of Zdenek Stybar. At first glance, it looks very similar to the current Domane, but on closer inspection the differences are clear to see.

The biggest change seems to be the new Isospeed decoupler that has been placed into the head tube to improve front-end comfort, while the seat tube, down tube, and cable entry ports all seem to have received a redesign.

New disc brake bikes on the way from Canyon, Giant, and Merida

Say what you like about the UCI, but it certainly makes life a little easier for journalists trying to work out what the big bike manufacturers might release next. An update of the UCI’s list of approved frames this week saw the addition of a Canyon Ultimate CF SLX Disc, a Giant TCR Disc, and a Merida Scultura Disc, three bikes that aren’t to be found in the manufacturers’ 2016 catalogues.

>>> What disc brake bikes will the pros be riding in 2016?

We saw a prototype version of the Canyon Ultimate CF SLX Disc at Eurobike last year, but have seen neither hide nor hair of the other two. We’ll just have to wait and see if Giant and Merida have anything up their sleeves for the cobbled Classics.

Muc-Off’s new chain will save you six watts…

Muc-Off Nanotube Chain Optimisation

…and cost you £140. Yes, one hundred and forty pounds. Although that might seems a bit easier to stomach when you consider that the chain that you buy will have gone through a similar treatment process to the one that Bradley Wiggins used when he broke the Hour Record.

>>> How to lube your chain (video)

All that money buys you a Shimano, SRAM, or Campagnolo chain that has been “painstakingly speed graded and run-in under load during which data is taken to find its optimum. Now it’s sonic cleaned in several formulas and hand treated with the Nanotube formula, then nanotube particles are applied.”

So now you know.

The turbo trainer that will fit in your hand luggage

If you’re off to a race but don’t want to carry a heavy set of rollers or a turbo, then the Omnium Travel Turbo from Feedback Sports may well be of interest, which weighs just 6.21kg and folds down to fit into its own carry bag.

Once you’ve unfolded it, the rollers have progressive magnetic resistance, with the bearings being sealed and not requiring any maintenance. UK availability is set to be the end of March, with the Omnium Travel Trainer set to cost £349.
