Excellent energy bar, very tasty and easy to digest, and delivers a good dose of carbs

OTE's Duo Bar is based on the rice cake energy bar concept that is popular with many of the professional race teams. OTE partnered with Team Belkin this year to help them develop and evaluate the bar in the hardest sporting environment.

The Duo Bar - available in chocolate and this newly launched vanilla flavour - contains crisp rice, whole fruit concentrates and whole milk powder. It's quite a different texture to other bars, less sticky for a start which has the added benefit of not leaving a residue on your fingers.

It's an easily digestible energy bar; almost too easily digestible as you can find yourself munching through it pretty quickly. It tastes more like actual real food than most energy bars, and this means it's really easy to munch through a pocket load of them during a ride. And that means you can still stomach them even towards the end of a six or eight-hour ride, which I did recently. We take this testing seriously y'know.

Of course taste is a subjective matter. A few people have tried them and found them a bit strange at first, while others have warmed to them instantly. I haven't tried the chocolate but I'm a big fan of the vanilla flavour. It works because it's very mild, almost plain in fact, so very inoffensive. The white chocolate chips on the top are a nice touch and don't melt even if a bar has been stored in a jersey pocket for several hours.

A novel feature, for an energy bar anyway (it's pretty popular in the confectionary market with chocolate bars) is that the bar is split into two. Quite simply, when you open the packet you can extract just half the bar and leave the rest wrapped up. Now I've never had a problem tearing off a chunk of a regular energy bar, but the OTE split bar approach does make it much easier to do this, especially when you're riding and not stopping to eat, and especially when you're riding hard.

The other benefit of the two halves is that one piece delivers 20g of carbohydrate, so you can easily manage your carb intake during a ride or race. OTE says the bar is high in carbohydrate and low in fat, with 40g of the former and 4g of the latter. OTE also says this is adequate for 40-60 minutes of cycling, though that of course does depend on how hard you're riding.

There's also 10g of protein in each bar so they're good for recovery too. Not only that, but they've packed a load of vitamins and minerals into each bar. The numbers compare favourably to the main competition in the energy bar market but let's be honest, most people are going to choose a bar based on taste and how palatable it is, assuming it of course delivers the necessary carb boost. The vanilla Duo Bar hits the spot in that department, it's really the best tasting energy bar I've yet tried, and I've tried them all.

They're priced at £1.79 each or you can bulk buy in packs of 24 (currently at £38.66).

Why is there no picture of the bars unwrapped?
