2021 has seen the spread of high pivot bikes from small brands to big brands with frames made from everything including carbon, aluminium and even bamboo
Billy, the founder of Howler Frameworks is now throwing his own hat into the ring with his new frame, the Howler Fenrir.
Based in London, Billy established Howler Frameworks in 2018 after taking a frame building course at the Bicycle Academy, complementing his career as a bike mechanic. Like most frame builders, Billy started out with a hardcore hardtail build but following a period of furlough in 2020, decided to push his skills a bit further with the Fenrir. This is only the 12th frame Billy has built but SRAM took notice of his work and asked him to exhibit it as part of their stand at the Bespoked Show.
The bike uses a linkage-driven single-pivot suspension system designed by Billy that bears more than a passing resemblance to the old Scott Gambler. The bike has 150mm of travel in the configuration shown here but increasing the shock stroke by 5mm will allow the bike to become 160mm travel. The linkage has been designed around a coil shock with a linear progression.
This prototype is roughly equivalent to a size medium and has a 446mm reach, 75° seat tube angle, 64.5° head tube angle and 6mm bottom bracket drop. Currently, the prototype frame is built from 4130 Cromoly but as a production model Billy would look to use Reynolds or Columbus steel. Eventually, Howler will stretch to a four model range with a dirt jump bike, the 27.5" Rune hardtail, a 29er bike packing bike and this 27.5" full suspension bike. The Fenrir is set to be released in Q2 of 2022. For more info and to follow its progress, follow Billy on Instagram at @howlerframeworks

The aluminium parts of the linkage have been machined by Rideworks but the rest of the frame is Billy's handiwork
