There are bike dorks and then there are bike dorks. Today's podcast sees Gustav Gullholm, AKA Dangerholm on Instagram, take us through some of his wildest creations. How about a sub-30lb Scott Gambler downhill bike? Or his take on down-country, a 100mm-travel Spark that employs an ingenious dropper post integration system that ties into the bike's rear-suspension? Of course, all of these crazy machines have also been scraped down to bare carbon... with a big ass knife. Yeah, we had questions for Gustav.

If you're a bike dork, Pinkpod 43 isn't one to miss.

January 26th, 2021

Yeah, but wouldn't he save even more grams by scraping off some carbon as well?

Scott Gambler world s lightest
Gustav's raw Scott Gambler weighs less than 30lb and, according to him, very practical. That weight includes proper downhill tires with inserts, four-piston brakes, and even 200mm rotors.

Another of Gustav's bikes uses a heavily modified TwinLoc remote that controls not only the rear shock but also the dropper post. Oh, but not the fork.

Hosted by Mike Levy (usually) and featuring a rotating cast of the editorial team and other guests, the Pinkbike Podcast is a weekly update on all the latest stories from around the world of mountain biking, as well as some frank discussion about tech, racing, and everything in between.

 As a huge bike dork, I love Dangerholm content! Will have to enjoy this tonight with a choice beverage in hand. Great to have the podcast format to avoid the inevitable thigh envy!

 Haha thanks for the support man! Best regards from both me and the thighs.

 @mikelevy So if pinkbike sent Dangerholm a Grim Donut to make as light as possible would the project be titled “Slim Donut” or “Danger Donut”?
  • 7 0
 Grim Danger?
  • 2 0
 I think the best thing would be to send @mikelevy with the Grim Donut to Mora, then he and @dangerholm could test each others bikes out in the local bikepark "Gesunda" (Levy should be warned though, Gustav is a podium contender in both national level XC Marathons and local DHs).

 Gustav, you are a huge inspiration for me! Between you and Martin Grey (ETOE) I've gotten the balls to hack apart some bikes of my own and pull some carbon off. Bike #2 coming this spring! Love your work Gustav.

 Thank you for your kind words, happy to hear you're doing some cool stuff and that I could be a source of inspiration. Keep up the work/hacking!

 @dangerholm: I was hoping your thighs could be an inspiration too but mine just won't grow like that....

 I've never understood why he uses all that twinloc stuff on his bikes. He could make his bikes even lighter by taking that stuff off.
  • 8 0
 I think it comes down to the Scott bikes that use TwinLoc being designed around a lockout, so they might be a bit too active for some riders without.
  • 7 1
 Like you hear me say in the pod, I honestly do like the system for XC and trail bikes and wouldn't want to build one without it. If it's more about descending I totally get why you wouldn't want it, for example I'm hoping myself that Scott some day release a non-Twinloc Ransom with killer suspension.
But when it comes to XC training and racing it's just so good with a remote traction/lock-out system since you spend so much time out of the saddle pedaling.

 @mikelevy: the gambler should be single speed, so much weight saved that way and I never use my gear at the park, only need to push that last part to get to crank it up.

1) What tires, inserts and tubeless accessories do you use on your personal bikes?

PS -I love Dangerholm just like everyone else but have to actually listen to the podcast prior to commenting on that.
  • 2 0
 I'm usually using the stock tires that came on the bike I'm testing, but I do have 2.35" Hans Dampfs on my cross-country bike. I get why inserts make so much sense, especially as it's rocky where I live, but I'm kinda meh about them. I have a few of most types of inserts and have been meaning to do some sort of comparison video in the future. Besides that, I always put on some nice aluminum valve stems and add one cap that has a built-in core tool in case one comes loose on a ride.
  • 1 0
 @mikelevy: Thinking of trying rimpacts as the EXO casing tires I use always get destroyed at the rim interface rear only. Double downs are a little overkill until our friendly neighborhood Penticton rock kills the lighter tires. As you have figured my WOKE tire pronoun is "Max". I identify as a Maxxis user. Smile

I have a feeling that in 5 years we will all have some lightweight version of them - at least rear only on most bikes. Curious for you to have a group discussion on this!

Ride safe and hard Mike!

 @dldewar: For sure, inserts currently make too much sense, no matter what I say about them. But yeah, hopefully there will be some sort of even lighter and better-integrated solution in the future.

 @mikelevy: foreshadowing

 @mikelevy: I have the pink pepis inserts in my xc tires. They are quite light. I'm surprised they have not garnered more attention thus far. I'm curious about all the new shapes and materials, and how they'll affect ride feel. I'm excited for you all do do some testing as I'm curious, but current set-up works, so I can't be bothered to mess around with it.

 @aquanut: Mr. Aquanut - I have been looking at Pepi's inserts but could not find anywhere in North America that sells them. Curious where you got them from?
  • 1 0
 @dldewar: I think it was Bike24. I ordered them along with a boatload of Maxxis tires which more than made-up for the shipping costs (~$25usd). They shipped quickly even during the pandemic.

 I will be buying a Marshall because it’s made in Canada. It’s not even exactly what I wanted, but this is very important to me, even as a budget buyer. I had my heart on a Norco Sight AL frame. That’s how much NA manufacturing means to me.

 Chris King? Please, still incredibly good.
Question for them is: I see lot of love these days for fast engagement hubs. I’ve been a die hard Chris king guy for year but have recently tried i9 and newer fast engagement hubs and had reliability issues. My question is do you go for the fastest hub you can afford, or do you spend money on hubs that don’t die. Cause y’all never talk about King
  • 1 0
 Oh, and why are a lot of hubs so damned noisy? I understand the mechanism but they do not need to be that loud

I ordered 3 bikes last fall for me and the family. 2 from Rocky Mountain and 1 from Santa Cruz. Do you actually think they are going to show up in the spring? Or do you think this parts shortage will effect these companies and I will be the last to know?

 Gustav, Your bikes rock and I like your unabashed dedication to functional super-light mountain bikes. I was interested in your remark about having the opportunity of building a premium titanium hardtail. Do you see advantages in using this material with a small weight penalty compared to carbon?

 Great components, with an engineering eye for assembly and detail. Like Singer for mtb

 100% too much grease on those Dt ratchets caused them to not engage fully and slip. I don’t recommend it but put my ratchets in a parts washer and only put Dt grease around the edges
  • 1 0
 I used to get by with *regular* application of tri-flow on DT star hubs.

 @dirtyburger: Same here, or any other thick liquidy lube that's not wax-based. I love the loud buzzing, especially when I'm behind someone so they know that I'm just coasting haha

 @mikelevy: I've got a love/hate thing with loud hubs, currently hate. Very keen to lace up one of those Box silent hubs, way cheaper than the other fancy silent hubs. Out of stock of course.

 Very enjoyable podcast, but you negelected to ask @dangerholm the question on all our lips:
How on Earth do you pay for all that trick gear (the stuff that's not supplied free anyway) on a bike shop wage?
  • 1 0
 He's sponsored by Scott, which helps Smile
  • 3 0
 @chakaping Like Mike says, these days I get the frames from Scott and also have help from several other companies. But up until 2019 everything was paid for by me, which for example includes the two World's Lightest XC bikes, the Genius and my Klein inspired hardtail. It was simply a matter of work hard play hard, and also getting rid of old builds to be able to purchase new ones.

 @mikelevy - Did you ask @dangerholm if he is interested in modding a Mini?

 He did mention that he sticks to bikes, not cars. I think the Mini is already around 600kg or something Wink
