Clif Bar



You won't fall off the cliff in a hurry with these bars

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

Clif Bar's original energy bar product packs a tasty and filling energy punch, in a large variety of flavours.

Not content with the usual simple flavours we see so often with energy bar products – chocolate, strawberry, lemon, banana, and the like – Clif Bar has always impressed with its variations. Alongside a new coconut chocolate chip flavour, you can also have chocolate chip, crunchy peanut butter, oatmeal raisin walnut, blueberry crisp, chocolate almond fudge and white chocolate macadamia.

All are super-tasty – I would happily eat all of them – and yet not too sweet or sickly as the names sometimes suggest. In particular I like the new coconut chocolate chip flavour, though it doesn't seem readily available in the UK yet.

Each flavour has a slightly different nutritional profile, which will have a marginally different effect on the body. While some might like to delve into these margins, personally I don't think they have a noticeable effect on performance. I'd go with your favourite flavour, unless you have a particular favourite ingredient you want to take advantage of (like the Omega oils in the oatmeal raisin walnut flavour, for example).

So, from each (coconut chocolate chip) bar you get 256 calories of energy, derived primarily from oats. That means there are 6g of fat per bar alongside 38g of carbohydrate (21g of which are sugars). That's quite a hit of energy from a bar that weighs in at 68g – portable enough to be able to carry three in a normal sized jersey pocket.

The high glycaemic index (GI) sugars pick you up from your energy slumps very well indeed, while the low GI carbohydrate helps prolong the energy release. That means you feel satiated for longer. The size of the bar is almost perfect if you wanted to use one as a healthier option in place of your usual flapjack or cake at your coffee stop.

Impressively, each bar contains 10g of protein too (markedly more than most energy bars on the market). Proteins take longer to break down and digest than simple sugars, which means this also assists with staving off hunger. Additionally, feeding your system with a small amount of protein on your ride provides the amino acids to support recovery and maintain lean muscle in what, after all, is a very catabolic (breaking down muscle) and draining activity. I wouldn't sacrifice my post-training recovery shake for these, but using them during my rides can only be helping matters.

Another thing I particularly like about these bars (for the record, they're not your usual rectangular bar; closer in shape to a rounded cookie) is the micro-nutrient content. Supporting energy release and general healthy wellbeing are vitamins B6 and B12 (especially key in supporting energy release), A, C, D and E. You'll also spot helpings of niacin, thiamin, riboflavin, calcium and magnesium thrown in too, which makes this the most rounded energy bar I can remember coming across.

As a result, taxing effort in the saddle is supplemented by a top vitamin profile, which in turn helps boost immunity as well as improve energy release and recovery. While it's always difficult to quantify this, I can report that my performance on the bike was consistent and strong while using these bars, and I never found myself suffering from 'test fatigue', thanks to the flavour options I had.

Packaging is of a good quality and easy to open, and the bars sit well in your pockets as you ride along, dealing with repeated heat changes. Texture is also very good regardless of the flavour you choose – I didn't notice any excess grease or oil, yet the bars aren't too dry. I liked to take a swig of water whenever I had one, but there's nothing uncommon in that with whatever bar I eat.

As with most sports energy bars, they aren't cheap: they retail at an RRP of £19.08, but at the time of writing you can buy 12 bars for £13.99. That works out at £1.16 per bar – which for the energy and rounded profile they provide is remarkably good value.

At the end of the day, these bars contain lots of energy, a more comprehensive nutritional profile than I've seen in any energy bar, they taste very good, and are relatively good value if you scout around online. Therefore, I highly recommend them.

Recommended usage:

For best results, CLIF Bars should be eaten about one to three hours before exercise along with water to prevent hunger and supply energy to working muscles. During prolonged, lower intensity exercise such as hiking or bike touring, CLIF Bars can be eaten during activity to help satiate hunger and meet carbohydrate demands. CLIF Bars can also be eaten as a snack between meals or during a long, busy day to help sustain energy.

Rate the product for quality of construction:

Bars hold up well. They're not always completely uniform in size, but then that just gives an air of homemade-ness, which some will like.

Rate the product for performance:

About as good as I've seen - sustainable energy with a quick hit of sugar to deal with slumps. If you have a whole bar in one go, it's like a mini meal.

Rate the product for durability:

No complaints - they'll survive repeated transport on rides.

Rate the product for value:

The RRP is on a par with most energy bars, but you get 68g worth of bar for your money, boosting value a little. Find them for a discount (as I have), and they're a smart, relatively cost-effective choice.

Tell us how the product performed overall when used for its designed purpose

Comprehensively well. I'm very impressed.

Tell us what you particularly liked about the product

Homemade feel (it doesn't taste or seem processed), and the great nutritional profile.

Tell us what you particularly disliked about the product

Honestly, nothing springs to mind. One might argue that the varying nutritional contents based on flavour confuse the issue - but unless you're a top pro, I don't think this will have any effect at all on your performance, especially if you have a healthy general diet.

Did you enjoy using the product? Yes

Would you consider buying the product? Yes

[pedant] two twins? so four people?



mejungleman@out... | 8 years ago

I'd love to see at test of two twins, one doing a race eating rubbish, and another eating energy bars.

Pretty sure the engery bar team would win, but it it would be a hilarious and interesting experiment.
