Stan’s NoTubes Tire Sealant


SO GOOD
Probably the best-known sealant, Stan’s is popular for a reason – it works. The hole left by our biggest screwdriver was sealed within just one or two revolutions of the wheel.

To make things harder, we stuck the tool in again and wiggled it around from side to side. The tyre sealed up eventually and we were able to reinflate it to 36psi before the seal broke once again.

NO GOOD
Sidewall punctures are dealt with OK, but performance isn’t quite as impressive as with the two highest-scoring options here, because the Stan’s sealant doesn’t cling to the tyre casing quite as well.

Price 22$ for 568ml (=39$ for 1l)

Nukeproof Vector AM Comp Cro-Mo saddle

The Vector AM is pretty race focused, with minimal padding. There’s a deep (if narrow) pressurerelief channel to keep the blood flowing where it’s meant to. Used with bib shorts, we found it pretty comfortable for shorter rides and suffered no pain or discomfort in the central region. On steep climbs the slightly downturned nose provides a reasonable forward perch, while the svelte profile and smooth edges make it particularly unobtrusive when moving about on the descents. It’s quite stiff though, and can feel harsh on long rides or bumpy ground. We definitely wouldn’t want to spend much time on it without a chamois. It’s heavier than we’d expect for such a lightly padded perch too. There’s a lighter Pro version with titanium rails for $105, but at 241g it’s only 10g lighter. Weight 251g Price $67

Merida Big Seven 100

We've rolled up to our local woods, with a meandering blue trail, some natural wooded tracks and a bit of fire road chucked into the mix to see how the Big Seven 100 tackles trails that entry-level riders are likely to cut their teeth on.

Cannondale Trail SL 29 SS

The fat aluminium tubes are a constrast to the skinny items seen elsewhere in the test, but this rigid Cannondale uses them to create one of the most old-school - and lightest - rides here.
