This year the company is celebrating its 87th anniversary and is with that the bike component brand with the longest history on record. And it’s proud of its heritage as Sturmey-Archer shows it on some of its newest components like the new XL-FD front drum brake hub.
As for this new drum brake, it is designed to meet heavy duty demands at city and transport bikes under extreme weather conditions whilst also allowing sufficient control, even for inexperienced users. The new XL-FD front drum brake hub has an increased size and capacity 90mm drum brake, all encased in an equal-size flange hub for ease of wheel building and fitted with sealed cartridge bearings, as standard.
Alongside this ‘standard’ version there is a version with 14mm axle for the real heavy duty work – type XL-FD (HD). And finally, type XL-FDD which is the new drum brake combined with Sturmey-Archer’s hub dynamo lighting unit.
Internal gear systems
Demand for fixed wheel bikes has increased in recent years, particularly in major cities. Some help climbing steep hills would be appreciated by ‘fixie’ riders and Sturmey Archer’s new type S3X answers that demand.
The new hub has two lower gears, 25% and 37.5% below direct drive. The epicyclic gear system is encased in a cold-forged aluminium alloy shell and this will be also available in anodised colours to allow customisation of the bike. There are two new gear controls. A bar-end shifter to suit race-type bars and a ‘thummie’ gear lever for straight bars and seat-tube fitment. Available begin 2009.
Also new in the Sturmey Archer line-up for MY 2010 is a wide ratio 5-speed. The rationale behind the new wider ratio 5-speed range is, according to the Sturmey-Archer Europe people, quite simple. It is to offer the gear range of a 7-speed hub with a price closer to 3-speed. This allows both up and down-grading whilst hitting the right price points.
Overall range of the new hub is 256% and, here again, the hub shell is cold-forged in aluminium alloy. The coaster hub brake versions were already supplied in 2008. For 2009 versions are offered without brake and with built-in drum brake and with attachment to allow disc brake use. There is even a version with oversize drum brake to pair up with the 90mm type XL-FD front hub with drum brake.
The new type TS55 twist shifter allows easy gear-change and there will also be a 5-speed ‘thummie’ similar to that offered with the S3X fixie hub. Last but not least, Sturmey-Archer finally has available all of the new wider ratio 8-speed hub range. So now also with drum brake and with attachment for disc brake. The new hub is easier to fit and adjust and also much more user-friendly.
