Burgtec introduce offset shock bush/hardware
Burgtec show off their new offset bushings and hardware.
So we have seen offset bushings before but Burgtec now say that they are offering their ‘covert’ technology to the masses! Interesting.
OK, so what do offset bushings do? Well they are mainly used to slacken the headangle of your bike or of course steepen it if that is what you want. But by using these bushes you don’t just change the headangle of your bike, you can expect to experience subtle changes to the rest of your bike’s geometry (BB height, etc.). Here’s the press release:
PRESS RELEASE
Burgtec introduce offset shock bush/hardware
World Cup winning ‘covert’ technology available to [the masses]
• Innovative solution to allow custom head angles set in a few moments
• Used extensively in UCI World Cups including Marc Beaumont 2010 win at Val di Sol
• Made from grade 5 titanium for lightweight durability.
For years offset shock bush/hardware has been used covertly on World Cup circuit by many of the top riders to gain performance improvements. Following world cup success with Marc Beaumont in 2010 and subsequent demand from top riders the Burgtec team have developed a production version of this innovative component.
The offset hardware allows the head angle to be easily adjusted by shortening or lengthening the effective eye to eye of the shock. In recent times as the trend leans towards steeper and faster tracks the bushes have been used to relax the head angle. This makes the bike feel more stable at speed and even more planted on steep sections by throwing the front wheel further forward. The bushes can be used in the opposite way to steepen the head angle to improve the bikes geometry for sprinting if the track is more pedaling orientated. This pitches the rider more to the front of the cockpit and more on top of the bars which is better for sprinting.
Our offset hardware was used by Marc Beaumont when he won at Val Di Sol 2010 World Cup. After Marc’s victory more and more riders approached Burgtec to help slacken their head angle using the innovative offset shock bush/hardware.
As Marc Beaumont said “Burgtec’s offset hardware helped me to dial the perfect position on my GT Fury, giving me the Win at Val di Sole and have my best year to date”.
The Burgtec offset bush/hardware allows between 1 and 1.5 degrees of head angle alteration depending on the shock bolt size of your frame. 6mm frames will naturally get the greatest amount of alteration with the 8mm frames getting nearer 1 degree.
The offset hardware is made from grade 5 Titanium which is significantly lighter than its steel hardware counterpart but still maintaining the same excellent wear rating when compared to OE Aluminum ones; approximately 3 times. The hardware comes supplied with a proprietary o-ring seal, to keep out as much of the elements as possible, as well as DU bushes.
The offset hardware will suit all ½” shock eyelets so Fox, Marzocchi, Rock Shox 08 onwards.
The first batch will include kits to fit the following bikes (other is available to special order).
• Commencal 4X, Meta, Supreme 6, FR, Mini DH, Supreme DH all years
• GT Fury 10-11
• Lapierre 720/920 08-10
• Lapierre 720/920 11
• Orange Five, Patriot, Alpine 160, 222, 223 and 224
• Santa Cruz V10 05-10, VP Free all years, Blur LT 2, Heckler 07-09
• Santa Cruz V10 11 Carbon
• Scott Gambler 08-10
• Solid Mission 9 All years
• Transition TR250 and TR450 all years
• Yeti 303 06-08
The first batch kit sizes will be 19mm x 8mm, 22mm x 8mm and 30mm x 8mm so if your bike isn’t listed above but you know you need one of those sizes Burgtec can help.
The offset hardware is available immediately and is priced at RRP of £45.
Can you spot Marc Beaumont's Burgtec bushings!?
Interesting and cheap way of adjusting your head angle without having to change your frame.
My only questions would be, how does the bush not move, or does that depend on the bike and the way it tightens? Also would it change any other factors such as stressing the frame in certain areas as obvioulsly the bike would not be designed around the adjusted head angle?
Could someone confirm on an 8mm shock bolt offset, what sort of offset you can gain (in mm) from standard?
I’m trying to work out if I can gain enough each end & put a longer i2i (10mm) shock on a bike to increase travel, but (as close as possible anyway) retain the stock geometry
I know the frame will take it, but I need to know if it’s going to mess up the geometry too much (raise BB/steepen HA etc).
The bush/mounting hardware is clamped inside the frame so doesnt spin. 8mm shock bolt clamps these hard into place. The eyelet bush in the shock rotates on the bush/mounting hardware. I’ve heard quite a few WC guys have been doing it without any issue. These would be sweet on my Orange 5, wish i’d had them for the mega
I love the fact that these cost more than twice that of the competition – typical Burgtec! ok they are made from TI but really, how much lighter than the other metals used can they be? it’s about the size of my little fingernail. Go on, shoot me down – I am free and available.
^ hmmm similar thoughts! Lifetime of the bushes maybe makes worthwhile?
hmmm this seems awful similar to a certain steamer related companies product. also its a lot more pricey.. i think ill pass burgtec..
dirt dodger – you are assuming they are individual set a la the other offerings.
If this is a complete set (i.e. front & back) then they are nigh on identical price wise.
Please make a version for the Giant Glory – I would definitely purchase!
the ti isn’t used here for its light weight, its actually heavier than the alloy it replaces. the ti is harder than the alloy bushes, therefore lasting longer than the soft alloy ones.
good job burgtec
hmm pretty sure that because Kevin of Steamer Industries is selling his bushings publicly for the last while Burgtec now feel they can hop on the bandwagon and are offering an AMAZING SHINY TI VERSION… which provides zero benefit and costs twice as much. Yeah, great how they were a ‘covert’ mod for the pro’s but is this really all they can come up with to justify them being ti and costing so much and as a selling point over their competition? Think im gonna go into business selling pieces of Red Bull and Monster can that you can use to protect your brake calipers from dangerous and toxic mud, only 20euro and come with a free flat cap, get them before they sell out! Steamer life.
Interesting that they would use Ti. Last year in college I did a study on the use of different metals for different application which included bushing, and what I found was that the Ti caused the most problems. Problems like cold welding to the frame and bolts (becoming permanently stuck to Ti bolts) http://ultrametal.ca/images/coldweldrodend336.JPG Many sheared bolts..You need to use special greases to stop the Ti from sticking to everything.
It also tended to cause more wear on the DU bush than other metals.
Obviously Aluminium has it’s problems too. We tested a hard anodized alu bush vs a non anodized, The hard ano bush came out best in pretty much every test. It’s only downfall was fatigue life, Steel had the longest life span.
This is really only a summary of my full study but it outlines the main points.
In my opinion The best option for a bushings is a hard anodized alu one. Cheap, easy to make and lasts long enough. Ti is expensive and tough to machine and causes problems but lasts a long time. Steel is heavy and is prone to rust unless it has a corrosion resistant coating but has the longest life span.
Ehhh well these are a load of crap! Titanium is overpriced and pointless for such an application! Wooooow yeah ‘covert technology’ good job on the marketing front there burgshit, pity this covert technology has been available from Kevin at Steamer Industries for ages now.. AND its half the price.
Just a copy of steamer industerys product
And steamer industerys are cheaper
so were all agreed we love steamer’s pile of bits more than burgies bits. steamer steamer
I pumped up my front tyre really hard and let half the air out the back one. Slackened my head angle by 45 degrees.
£45 is for a complete shock which is really good value for money considering the material and that you get the DU’s/eyelets bushes too.
Beaumont used these in 2010 which is before we heard of Steamer. not that it really matters. just saying…
£45??? I’ll make them manually myself in about 20 minutes! Burgtec stuff is nice, quality kit, but also a prime example of how overpriced the bike industry seems to be at the moment.
£45 is cheaper than getting an adjustable headset where the bearings last about 2 wet rides.
good idea and a fair price, might treat my bike to some
Hmm using ti over steele to save weight? Here’s an idea get steel ones for a hell of a lot less money and then just go lay a couple of logs before you go for a ride. You’ll have saved more weight that way and saved money, perhaps you could spend it on a haircut that way you’d save even more grams and we all know you notice a huge differance when you shave 50-100 grams off the weight of your bike!
Kev has been making these offsets under the radar for the last 3 years. They were only sold in very small numbers to only Irish riders in Ireland.
I’ve also heard from him that he’s a few tricks up his sleeve still so keep an eye out.
Forums are full of people who can make stuff in about 20 minutes!
Not majorly high tech just being a bit cute onto stuff. Good attention to detail Burgtec.
I’ve got a spare 20 mins I think i’ll go make some avid code’s before bed!!!
its always good to shave weight of your bike, small bits even. ordered some earlier and burgtec said they’d get them in the post straight away
So much marketing bullshit ….
Hahaha I bet they’ll get them in the post straight away because at that price for a few bits of scrap they”ll not be running low on stock any time soon don’t they know there’s a recession on bike industry is taking the piss on the price of things this last couple of years
£45 for a worthwhile mod, no need for all the dissin.
John Wayne I agree! Someone else has done material science
Why do we continue to use Ti and ALu.. Steel is the only material that will last and do the job. Ti costs way to much
Really why buy Alu or Ti to save a few grams when it will wear out and most likely ruin your day!
Just get steel and enjoy zero problems!
Save weight on rotational mass. much better.
However I like the idea of adjusting your HA. No hating on that. Just think the material choice is wrong!
Its fairly commonly known that Ti and alu will cold weld together and Ti is notorious for binding. If this happened you d not only be looking at a new bushing but also a du bush and maybe even shock bolt, could end up being very costly indeed. And Mikes mum i m fairly sure if you used steel you could be very well be in danger of damaging the shock body if the steel used was harder than the body of the shock.
Tell me again who used these when he won in Val Di Sol?
Conky Im not talking about putting a steel pin straight into an Alu Shock body. You always put a DU bushing in.
Are u putting pins into your shocks with no bushing…tut tut
The price of £45 is for a full shocks worth.
Reason for Ti; Because we wanted to get the maximum offset it means the wall thickness of material goes very thin. I wasn’t confident aluminium would be strong enough for the longer sizes (anything over 30mm). It would be asking too much from the shock bolt. Steel would be a good option also but we wanted to make something light. With Ti being .6 the weight of steel we went for that.
‘cold welding’ I have never seen this on anything within the bike industry. As long as you use the correct grease, which is pretty much any of the major one’s available and strip things down regularly its not an issue. I’ve used them on my downhill race bike for years without any issues
For Ti and Al to seize together they need to be assembled with enough force to scrape away a portion of the naturally forming oxidised outer layer. The chances of you doing this pushing a pin inbetween your shock mounts are quite slim. The chances of you removing a large enough area for it to actually grip are even slimmer. The chances of both those occuring and then you leaving it in your frame for a good few years and then not being strong enough to simple break the “cold weld” with a slight tap are even slimmer than that. For some people a little knowledge really is a dangerous thing!!
And if someone can make 2 pins, 4 collars, 4 seals and 2 bushes in 20mins that is one hell of a workshop you got access to.
And finally, if you don’t like them that much, go buy them from Steamer for a fiver less. Simples!!!!!!!!!
Good mod… good work… good price
Could all the wannabe machinists and metallurgists pipe down.
Yes £45 seems pricey and yes Burgtec have over-reached on the marketing rhetoric, but what they’re providing you with is a sound product that makes a pretty significant change to your bike’s geometry for not a massive amount of money. (Consider the small volumes and multitude of variations they need to make).
If you want to make your own and have access to the kit to do it properly, then shut up and do it. However, it’ll take you more than 20 mins and don’t make them in Aluminium if you’re planning to slacken your bike out; as it won’t support the shock bolt properly and there’s a good chance of bending it or inducing fatigue failure.
Titanium is more prone to galling than steel, but then so is Aluminium. Whatever you use, make sure you get a fine finish, otherwise you’ll wear out your bushes prematurely.
My ONLY issue is this will alter suspension characteristics too (your essentially moving the bike into its travel – 8mm total offset from centre in a 3:1 frame is like putting a bike 1″ into its travel)
This could be especially important with ‘sensitive’ suspension designs with a lot of rate changes throughout the stroke.
A good solution non the less. Ill stick to one of these though: http://www.workscomponents.co.uk I tried a shorter shock once on a bike, which is similar to this and it ruined it as i couldnt get the last bit of travel due to how progressive it became.

Oh, and if there only £5.00 more made in titanium from a company with warranty and reputation i know where my money would be heading, sorry Steamer but the video of you producing parts on a manual lathe didnt help.
Jake
ha ha ha!! Rupert, the wannabe metalurgist, machinist and failure mod analyst. Bosh!!!!
Don’t Forget Steamer Industries had a video of how there made…(Filmed By Me) MARKETING BOOM
