Interesting little test they've done here (well, I find it interesting anyway!). Effectively a chainless race just relying on handling & suspension down a particular course (would result be different down a different course?).

2.5 seconds over a 30 second trail is quite a difference. Why is the BMC quicker than the Jekyll? Why does it clearly carry speed so well?

We did three runs on each bike and took the fastest one.

Better if they'd have taken an average of the three runs IMHO.

Better if they'd done 20 runs, discarded the fastest and slowest 5 then averaged the rest.

Or 1000 runs and discarded the slowest and fastest 100?

Now you're being pedantic :p

On a serious note, I'd go for the rider just having a better run. Or if it is equipment related, shock/fork setup rather than one bike really being 6% faster.

Poor testing process. To take the fastest times as a way to compare, they'd need to do a lot more runs on each bike to be sure that they were actually achieving a run on each that was reaching the potential of the bike. As it is, it could just be that they did one really good run on one bike.

or TINAS' method gives a better overall result

It does say "this was just a bit of fun, dont read too much into the results"

It doesn't say which order the runs were made, could have just been the rider learning the trail conditions.

I suspect the fastest time was on the bike which felt most like the rider's normal stead.....

Yep, and the testers should be blindfolded to avoid any bias. 😛

Maybe one had narrow bars and could take a different line early on that gave it an 'advantage'?

Looks like they're testing 150mm full sus bikes on a trail that wouldn't trouble a 100mm hardtail :/

Fair enough though Kit, that's where most people ride them.

The same could be said of most DH tracks, 95% of its rideable on an XC bike, but in a 2 mile track 5% of it is 160m isn't, so you tend to pick a bike for the 5%.

Bit like buying motorbike, do you buy the boring steady BMW tourer that'll do 500mile motorway blasts with ease, or the race replica that makes you heart skip a beat on a wiggly b-road between the mtorway and home?

They didn't even need to do the test.
Just show the bikes to Tom down the pub, and get him to say which one was probably the quickest when he rode it 4 weeks ago....
That's science, baby.....

Ignoring the fact that they need to do more runs, you would also have to set the suspension on each to its best for that rider.

Way too many variables.

You would also pick better lines as you did more runs.

Well, if you read MBR I'd say that whichever bike had the shortest stem & bars wider than your house will be 127% faster. And contrary to what we said last month, or what we're going to say next month, the one with less is more, more or less...

Twitter response from MBR:

Just for the guys on the ST forum, the bars/stems/tyres/suspension all set-up the same for 'the Stig'. Rode the same line each run and ridden that trails hundreds of times. 😉 PS Tom was too drunk to form an opinion.
