Throwback Thursday: 7 Cool Issues From Eurobike That By no means Made It Large
Ever since Gwin’s legendary chainless run, separating suspension motion from chain forces has turn into the objective of engineers within the mountain biking world. We have seen some easy options corresponding to Gee Atherton’s neutral gear and a few extra complicated just like the O-Chain chainring spider. Maybe essentially the most promising was Canyon’s DisConnect system that was first previewed at Eurobike in 2016.
The bike’s modified hub is residence to a DT Swiss Star Ratchet clutch, and the 2 Star Ratchet wheels are moved aside by an advanced system of three movable pawls that stretch outward from inside the particular axle. As soon as the thumb paddle is pushed, the Star Ratchet wheels separate and the freehub and drivetrain have zero affect on the bike’s suspension. After all, this implies pedaling may also lead to nothing; it is as if there is not any chain on the bike in any respect.
4 years and a new iteration of the Sender later, there was no additional information on the system so we’re assuming it has been shelved at this level.
Scurra’s Linkage Enduro Bike
Transfer over Structure Cycle Works, transfer over Cannondale, transfer over any model that has designed a mullet bike, Austria’s Scurra was arguably effectively forward of the curve when it introduced its wild 2 Enduro bike to Eurobike in 2017.
The 170mm Trelever linkage fork is pushed by a Magura shock after which immediately behind that’s one other shock that drives the 200mm of rear journey. Different cool options about this bike have been a 29″ wheel up entrance with a 27.5″ wheel out again and geometry that is adjustable with out eradicating a bolt. This body would have set you again €5,000 (together with each shocks) however sadly it seems like Scurra has closed its doorways for now, with no updates on the bike and no posts on social media since 2018.
We have seen loads of linkage bikes down the years and there is but to have been one which’s actually caught. We have undoubtedly discovered some fascinating outcomes each time we have examined these wild-looking machines and would have cherished to have given this one a go too.
Marzocchi’s Espresso Dropper Put up
In 2014, we got a sneak peek at a dropper post that was in the works for Marzocchi. Aimed to be OE solely, we noticed two 150mm fashions with inner and exterior cable choices. The ‘Espresso’ identify got here from Marzocchi’s Kashima-esque coating, which was additionally featured on its forks and shocks on the time.
We noticed the publish once more at Sea Otter and Core Bike within the subsequent six months, however in July of 2105 Marzocchi shut its doorways earlier than being purchased by Fox in October. When the model resurfaced, it got here again with a brand new look, new merchandise, and no Espresso dropper. It wasn’t till 2018 that the Italian marque would launch a dropper and that was referred to as the Switch, which turned out to be just about similar to its Fox Efficiency cousin.
Bear in mind Nitro Shox? It is in all probability laborious to not on condition that we have written three articles on it at numerous commerce reveals since 2015. At Eurobike 2015, we noticed its first-ever shock and we have been getting a sluggish tease of it ever since.
The Nitro Shox works on the identical oleo design because the Millyard Shock that has additionally been in and across the mountain bike scene for quite a lot of years. It is a design that is carried over from airplane touchdown gear and is claimed to supply efficiency advantages with none of the changes wanted which can be discovered on conventional mountain bike shocks. There is a extra in-depth take a look at the way it works, here.
We noticed an up to date model of the shock at Sea Otter in 2017 and have not actually had any updates since. The corporate continues to be energetic, however a manufacturing model of the shock nonetheless would not exist. We’ll proceed to observe each Nitro Shox and Millyard’s progress to see if something ever hits the market.
CeramicSpeed’s Chainless Shaft Drivetrain
A real innovation or only a solution to get journalists to go to your stand and take numerous photos? We’re nonetheless uncertain as as to whether CeramicSpeed has any critical intentions of growing this shaft drive idea, however there is not any doubt it is an fascinating thought.
As an alternative of a series, the Driven drivetrain makes use of a shaft with a curler pinion on every finish to switch the facility from the chainring to the cassette. To make it work on a full suspension bike, CeramicSpeed needed to make it telescoping to deal with axle paths and altering chainstay lengths of a full-suspension mountain bike. Canyon additionally needed to construct CeramicSpeed a particular body with an elevated chainstay to accommodate the telescoping shaft.
Once we noticed it final yr, the idea was nowhere close to manufacturing. The shaft might solely journey a small distance, however CeramicSpeed claimed that there was theoretically no journey size that might be too lengthy. The principle downside right here is that the system will solely work on a motorbike the place the pivot is above the axle, so on one thing like a Horst hyperlink bike this merely would not be doable. CeramicSpeed and Canyon additionally needed to redesign the rear triangle of the bike to make the system match, one thing that must be thought of on most bikes if the product ever got here to market.
It is solely a yr outdated however we might be very shocked if we see an replace to this challenge any time quickly.
Brakeforce One’s H2O brakes
Brakeforce One has been floating round since 2010 and we reviewed a pair of its regular brakes in 2014 but it surely actually caught our consideration in 2015 once we noticed these brakes that use H2O instead of traditional brake fluid.
Why use water? Effectively, BF1’s engineers say that the one purpose we use DOT or mineral oil is due to outdated know-how taken from the automotive the place fluid temperatures can get a lot increased than on mountain bikes, and that water is definitely extra warmth resistant than a hydraulic fluid with two occasions increased warmth capability, 5 occasions higher warmth transportation and fewer warmth elongation. It additionally has the advantage of being extra environmentally pleasant and sustainable than utilizing oil. Nonetheless, on condition that the boiling level of water is 100° C, and the boiling level of DOT fluid is 260° C, it is east to know why DOT fluid is the extra frequent alternative.
BF1 nonetheless makes the brakes and they are often purchased for €594.00 however they’re an especially uncommon sight and DOT and mineral oil nonetheless reign supreme.
