I've been seeing posts on G+ in the Mountain Bike group by a guy who customizes his bike to make it lighter. I've frequently found myself thinking he must be the epitomy of weight weenie and considered posting on here about him a few times, but have held back...

Until now:

Yes, that's right, he's now lopped off a few inches of front fork stanchion to save a few grams 😯

https://plus.google.com/+SebKMTB/posts/CPv5brDhWBK

Apparently the bike is under 6kg now.

I think that's the same SebK that posted on weight weenies.

Very odd character...

Google+ is horrendous.

Tried to follow what he was doing but gave up!

I was trying to think how that could possibly still work.... then I read "considering I was no longer using the rebound damper the right stanchion has no other use"

So there's the answer - it doesn't.

That window sill is minging.

So the Guy's built a 6kg death trap that doesn't perform well to impress some other weirdos on the internet, well I guess everyone needs a hobby...

But, the whole point of losing weight is to make a faster, more efficient bike, he's created a slower, less efficient bike, which just happens to weigh less.

I had an argument a while ago with someone about show cars, where to avoid unsightly leaks people would build the engines dry, or even devoid of internals completely, meaning you can't run the engine.

My argument was that if you deliberately build it in a way that means you can't drive it, it's no longer a car, it's a 1:1 scale [b]model[/b] of a car.

This bike is following the same principle. May as well make the forks from carved balsa wood.

His argument is that he runs them at super high pressure, so they're not-quite-as-bad-as-a-rigid. And he only rides in the park.

He's destroyed a nice set of forks, basically.

Has he confused bushings for dust seals. He reckons there is still stanchion beneath the bushing - err no there isn't. Your fork will at some point turn into a lefty when you least expect it - A lefty with a very floppy front wheel and no damping.

Teach me!!!!

Which, coincidentally, is the amount of weight he's going to lose when he's in hospital being fed through a tube.

I think it would (just) reach the bottom of the top bushing, if you allow for a bit of sag. But yeah, it's stupid and dangerous

Fine line with some stuff like this, on the one hand I think "fair play to him, he doesn't really want to ride his bike, just 'show' it, and he's done some mad things to it", then I think "what a muppet", and I probably rest there.

I recall a guy on MTBR 5 years ago or so who had a very very blue Ibis Mojo which was something like 18lbs - he had 250g rims, having put his ZTR Race rims in an acid bath. His USP was about it being the lightest 6" travel trail bike going, but I'd far sooner ride my XC hardtail on anything more than a pavement!

I also recall (and have just Googled for) a bloke on WW who spent hours with a Dremel 'tuning' an XT mech before sand blasting it, and that I do think is awesome! Free (man hours aside), no performance downside, but ends up with something truly unique.

Damp is obviously an issue as he has a dehumidifier type thing on the windowsill too. Clearly not very effective given the amount of mould on the frame!

There was a guy in a mag article 20(?) years ago - probably MBUK. Holes drilled the length of his cranks, cheap plastic brake levers (because they were lighter), saddle held on with a hose clip (lighter than a bolt) etc. I always did wonder which bit failed first - and what happened when it did. Would've made a good follow-up article.

Someone sent me a link to one of his threads on WeightWeenies.

He's a bit special isn't he.

No idea how the stuff actually works, just likes cutting chunks out of it. Like drillium on acid.

Wow. Why doesn't he just fit a rigid fork? Without the support from the lower bush, those are just going to bind.

Nutter.

There's people building lighter bikes from off the shelf parts. The ideas and passion are alright but a bit misguided at times

weightweenie innit

Don't bring Weightweenies (as in the OG site) in to it 🙂 The site banned him.

He's not really out to impress anyone much

You need to read the Weightweenie and MTBR threads that ultimately saw him banned from both. The G+ posts whinging about how no-one said hello to him when he first joined WW are another highlight 🙄

It's art, basically, not bike building. Hopefully it's sufficiently obviously mad that nobody copies it...

TBH I do like a bit of weightweenying but there can be craft in it; building a bike light without sacrificing usability, or building a bike light without spending a fortune. This just takes it off in another direction- how light can you go with no constraints at all.

Do like that XT mech njee.

BUt really not the ultimate weight weenie. Theres many rigid forks that weight half what he's butchered those down to.

Even if you account for a slightly wider rim and tyre its still lighter and will actually ride like an actual bike.

But yes, I realise that's not the point...

Just reading some of his threads on WW. He's a character eh?! Very weird. Definitely not the ultimate weight weenie, it seems more like indiscriminate filing of odd parts.

Very odd choice of frame too.

That's the best one I found.

Some of Google+ stuff is funny too, his 'followers' seem broadly to be people who are bemused by what he's doing, but don't understand why it's bad! On Kettle Cycles horrendous carbon rotors "won't they catch fire lol that would be bad?"

Slightly different calibre of user to WW, which once you filter through the idiots with too much money actually has some really clever people!

I only read the last couple of pages, but I think people were being a bit mean - he's definitely got some issues, but the way people were tackling some of the things he said was only ever going to back him into a corner and create more issues.
It's clearly a massive part of his life - I'd be inclined to be much more gentle with him.

That front mech njee posted looks great!

I had a quick squizz at those Sid forks.

He's removed the rebound assembly as he apparently no longer needs it! That rigid forked Stumpy is up there with those mid 00s All Mountain bikes you see on eBay with six jockey wheels bolted randomly to suspension linkages and three chains.

Just imagine the unholy combination of flex, uncontrolled rebound and steering imprecision. There's a visit to A&E there for sure.

Surely a bowl of All Bran is a cheaper and safer way to losing a few grammes where it counts?

He's definitely a man who could do with having someone sit him down and explain that just because you can do something it doesn't mean you should/it's a good idea. Where/what does he actually ride that makes all this effort (madness) worthwhile?

I think this sums it up.

Looking at those two threads i don't know who is worse, those trying to explain. Or those encouraging him.

Both are going to end up with him in a hospital somewhere.

The STW world masses struggling to get their heads round anything outside of their very normal lives.
Hardly. He's taking stuff that works, and making it not work in a way he simply can't grasp. Then "testing" it.

I think it'd be fine if he said that, but he makes all sorts of mental assertions about his frankenbike being better then everyone else's for x y and z reasons, which are total and utter bollocks!

Well to put simply I don't trust carbon frames . Too many issues for surface strength and if you crash hard the likely hood of a write off is high .

Thats it. Right there.
First time he hits a bump or pulls on the brakes the fork will collapse.

My Physics teacher did that.

Took a drill to his steel frame and made it look like Swiss cheese.

We all thought he was nuts too. His brother used to work in F1 and carbon fibre.

Who needs over engineering anyway?

No-one who actually rides would do that to a fork. Bet he never actually rides any of those creations in anger.

He reminds of a bloke in Bizarre magazine who built a guillotine and was fond of chopping bits of his body off.
When I read about him he was down to one arm minus a few fingers.
I guess it makes WW man quite normal.
He just seems oblivious to the flack he is receiving. Maybe this is some sort of self harming . Odd.

I think there's at least three different Sebs in this sentence. Me, the main subject "SebK", and lastly Whistler-based Seb Kemp.

It's probably my 222 you're thinking of, <36lb in 2002. A time when the average DH bike was 44lb or so, and 40lb was considered light.

[img] [/img]

Mainly just from carefully choosing proven light-weight parts (CX-Ray spokes, X-lite seatpost, foam grips, ea70 carbon bar, for example). Tyres, chain device and rims were heavy items though - durability and reliability is more important than weight saving on some items! I had a minimal 6-cog reduced cassette on it, which you'll note all the top DH bikes are coming with these days!

The best thing about that bike was the floating brake, I'm not sure hardly anyone makes those anymore. Annoyingly noisy once the rose joints started to wear, but it worked stunningly well.

Who knew Seb was Such a common weight weenie name!

Two brakes one lever can work, but I'd not want to do any serious riding with it set up like that. Not to say that one couldn't adapt to it though.
