Sunday trading: SiS nutrition, cheap inner tubes and more from Garmin, Continental and Castelli

For rides over 1.5 hours, you’ll burn through the reserves of glycogen stored in your muscles and therefore need to take on some additional carbohydrates so as not to ‘hit the wall.’

The gel format makes it super quick and easy to consume those necessary carbs – and there’s a huge range of flavours, so you’re sure to find one you like.

If you haven’t tried them before, why not get started with this multipack, including orange, apple, lemon and lime, cherry, fruit salad.

Or if you know what you like, you can pick up a bumper pack of 30 to keep you stocked up for a while.

Not only do worn tires not grip as well, leading to more nervous cornering, you’re also more likely to suffer some punctures on a set of rubber that’s on its way out.

Continental’s GP5000s are a firm favourite here at CW, being fast, grippy and – importantly – offering good levels of puncture protection.

Premio means "prize" in Italian – which is fitting, as these shorts sit at the top tier of Castelli’s range.

As a consequence, the RRP is quite high, reflecting the high quality of the materials and craftsmanship that goes into creating these shorts.

So it’s well worth taking advantage of this discount for the sublime comfort that they offer

For those in the UK, you can view Castelli's Spring and Summer collection at Wiggle here.

Garmin’s largest cycling computer delivers clear and accurate mapping, making it easy to follow your planned routes.

There’s a whole host of additional features this flagship model contains, which you can dig into in our review here.

Selle Italia is synonymous with quality saddles. If you are experiencing discomfort from excess pressure, it could be worth trying a saddle with a large central cutout, which – as you would imagine – go a long way to relieving that pressure

Inner tubes – along with a multitool, tyre levers and a pump – are a must to take with you on every ride. You don’t want to end up stranded if you’re unfortunate enough to suffer a puncture.

These ones are designed for tyres between 28 and 35mm, but there’s a whole complement of different sizes and valve types available on Wiggle’s website.
