XCKeith1, I was planning on coming up for the Peaks pootle (probably with gears) on the 19th, I've not been to Cannock since the Monkey opened so might well head over that way on the 20th if the weather is nice.
17mph average? Wow.
You forgot to mention that afterwards you killed a lion with your barehands in front of a spaceship full of supermodels...
welcome 'Spoon,my email is in my profile,best not to bring the geared bike tho,people tend to point and larf at them .
PS,if there's any of them Alien supermodels left,can you bring a few ?

Get your facts right, the lion was clearly on the spaceship.

http://www.sheldonbrown.com/gears/According to this with a 38:19 ratio spinning at 80rpm you'll get 12.3mph.
Do the maths...
Surely the maths only work for a fixie? If he coasts downhill without turning the cranks...
I take it that it was all downhill or flat?
I don't understand why everyone doubts 'spoons mathematics and engineering.
Not Having done even cursory research into this (other than riding a SS for 3years) I can tell this guy is an absolute legend and riding god.
That said; as part of an experiment last year I managed 15mph over a 9mile road lap on my 36:16 26inch wheel inbred, while on slicks. I think we can safely say I'm no bike god.
I'd say 17mph is do-able on a SS, on a fast trail - if you are very fit.
STW truly has a new "King Of Awesome." ๐
I ride around the edge of Richmond Park on my singlespeed (32:16) 26" MTB on my way home from work each day. Its barely offroad with a couple of steep hills thrown in. 8.3 miles and I average 11.5 mph.
I'm not supremely fit but neither am I slow. To average 17mph around Swinley singletrack would be pretty much impossible IMO.
There's something up with your computer.
On a road loop Dingwall-Ullapool-Ledmore-Bonar Bridge - Struie -Dingwall, 119 miles, average speed on a single speed 48/18 was 13.7mph. There's a few wee hills on the way, but the headwind was the hardest bit. I was just out for a cruise.
Fitter people would be much faster.
Never tried to measure speed on my mtb.
On the road on my MTB SS last weekend, with slicks. 90 miles in 5hr39 and not really pushing too hard. Same trip on a geared road bike my pb is 4hr57. Why isn't a road bike faster?
it is
Ok, after doing some maths turns out the average speed/odometer functions on cateye computers are in km/h despite the speedo being set into mph.......................
I'm not infact a riding messigha, I'm just a very naughty boy ๐
No, I meant faster than it is, not faster than the SS MTB, which it is. I was expecting a bigger difference.
Spoon, seems a bit peculiar to have speed in mph and distance/average functions in the foreign units. You sure you've pressed the right buttons? I know on Sigma ones it all cahnges when you set one.
Fastest I ever seem to get is ~ 20km/h average (~12.5 mph) on the SS. This is over about 30km averagely tech mix of singletrack trails, road linky bits and canal towpath on the way to work on a nice morning.

They're not on the 7 we have in our house ๐
[i]I'm not infact a riding messigha[/i]
Still, in your dotage you'll be able to look back fondly at the few hours you were and cherish the warm glow inside that it engendered.
(I'm with Dibbs - you sure the whoel thing just isn't set for km/h?)
No, the speed perfectly matches the reading on the garmin, and 80 rpm is 12.3mph. Even the Max speed is in mph.
But the odometer and average speed are in km, I got suspicious when spinning down the road and the 'average' speed was higher than the 'max' speed!
Cateye strada with cadenece (wired)
I've a sigma in the spares box, so I know how they work with conversion being done when entering the wheel size, the cateye just asks for a wheel size and does it automaticaly for the speed, but not other measurments for some reason.
was gonna say I rode into work this morning round the local trails, Greenham Common, quite similar to Swinley and I averaged 11.1mph. 13.78miles in 1hour:14min - and I'm not exactly slow. Even in the middle of summer in perfect dry conditions I've only managed to average 14.1mph on the same route - and I doubt I could hold that pace for a second loop. What I've found riding SS my is my times are much the same as on a geared bike. It's just a bit harder in some places, but then easier in others.

miles are for cars. km is for bikes.
"What I've found riding SS my is my times are much the same as on a geared bike. It's just a bit harder in some places, but then easier in others."
See, I was thinking that, and wondered if I'd be even faster fitting a 46t frotn chainring and a 23-11 cassette. 2:1 'singlespeed' gear, with 8 faster ones as well! But without the breaks inbetween 2:1 probably wouldn't get me up any hills.
surely off road having minimal jumps between sprockets is less important than on a road bike - there's so much more to upset your cadence that a 2 or 3 tooth jump isn't a problem?
I run 32:17 or 32:18 on the South Downs around Brighton - seems about right for getting up the hills and I don't seem to spin out on the flat much sooner than I would with a 16 at the back.
My old GT was geared 48/36 23-11 for a while and it was just b'stard hard to pedal and each time I needed to change gear I had to go through two or three shifts for a noticable difference - not really worth it for xc tbh... but it was good on the road with slicky tyres.
My SS was 32:16 when I had it, anymore I wouldn't have been able to get up the muddy slopes and any less would have been even more painfully clown like on the flat sections.

back in the 90s, i used to use a road cassette (13-23iirc) and it was ok, off road you were down onto the granny ring a bit earlier, but i could get up all the stuff my mates could, no problem.
i remember i did change gear a lot tho.
i'd love to run a nice straight through cassette on my MTB, makes more sense to me, for the trails I use
