Generation 2 – CHUMBA XCL – Sneak Peek

Hey guys and gals,

We thought we’d give you a sneak peek into some R&D work we’ve been doing over at CHUMBA. We decided to give the option of making the XCL a bit slacker and lower. So – we’ve been working on some versions of the bike with varying geometry.

Our current model uses a 68 degree head angle and a 13.5BB – so we decided to take the BB down by a 1/4″ and use a 66.5 degree head angle. This new version of the XCL will be adjustable – so you can run either settings on the same frame. In the lower, slacker version – the frame will be offered with a coil shock. We will be posting more details on this adjustable feature a bit later.

All we can say for now – is we are having a lot of good feedback – and should be able to provide more details soon.

Since 1993, CHUMBA Racing, based in Anaheim, California, produced America’s top competition mountain bike frames for racing throughout the world.  Whether it is 2-time NORBA national champion Duncan Riffle at the UCI World Cup, American veteran Lars Tribus at the Masters World Championships, or our full factory NORBA junior X race effort, CHUMBA closely collaborate with America’s top racers to produce and develop the world’s finest bicycle technology.
1. New VF2 Colors Arrive!  The Red VF2 – it’s a metallic red with a clear coat over it. Comes from some of the original EVO colors we used about 3 years ago — very similar to some of the color choices used by small American bike companies that do small lot production runs. Build it up with silver or black components and a touch of gold or red – complete bike pics to follow!  Please contact for ordering at  714-986-9100  or
2. Duncan Riffle wins European IXS Cup, Switzerland!  Here’s his race report:
Hello hello… its been a radical week for Team DRR/Giantnerd here in Verbier, Switzerland. Brad Benedict (teammate/male model) and I drove here from the last IXS Cup in Germany last week which was a great success for both of us riders. When we got to Switzerland the mountains looked massive, it was definitely time for some real ridin’. The weather was quite gnar-gnar due to being at almost 10,000ft in the Swiss alps! The weather pretty much does whatever it wants, whenever it wants. It was 80 degrees out early in the week so luckily Brad and I were able to keep our gorgeous tan’d bodies up to sizzle standards. Friday came and so did the rain, all day, and the temp dropped down to about 40 degrees which provided about a 5ft visibility range on the track. The course was extremely technical even in the dry with some big high speed sections and very tough root and rock sections in the woods that would prove to be nearly un-ridable in the wet. Qualifying began in the worst of conditions; thick sheets of rain, little bits of snow and literally zero visibility. As i set off for my qualifying run it seemed like a mission to get down without chewing on a root! Brad was just in front of me and managed to have a clean run accept for one section where he got way off course and attempted to pick a fight a tree! He ultimately finished a solid 19th. I came down with a good run putting me in 3rd. I felt happy with that as I was really just trying to focus on getting my lines smooth and conserving energy where I could, knowing that conditions would be better for tomorrow.

The next day brought the sun for race day morning! Yet it made for a very treacherous course as all the mud was now collecting over the rocks and roots making it extremely slippery. People were going down left and right in practice. Brad and myself were struggling quite a bit in morning’s practice runs just trying to piece all our sections and lines together with the difficult and changing conditions. However, come race time later in the afternoon I managed to shake it all off and just focus on what I needed to do. My race run was fast where I knew I could keep the heat on and just a bit conservative and controlled where I knew it was a bit slick. This week brought even more World Cup tour pros, including 1st place qualifier Nick Beer, a Swiss local (to this track) rider who got his first top 10 finish at the last World Cup in Andorra. Brad had a big crash in the woods section but managed to pick it up in the lower half of the run finishing in a very respectable 17th on the day. As yours truly pulled the big ‘W’ on the day and must admit it felt f*#king radical!! Nothing better than winning. Thank you to all my sponsors, friends and family for the support of Team DRR/Giantnerd…

We are off to France tomorrow for some photos and filming before we leave for Fort William, Scotland for the next round of the World Cup held this coming weekend. Be sure to tune your computers in to for all the live coverage Sunday morning. Till next time, over and out.
