Blue Lightning #7

First I got wrong rims and 2 different. Then I got a newer version of what I ordered which I kept with some compensation. Planned to get a pair of Ryde Trace XC 21 but got the new Trace 22 instead. A bit heavier but also 1mm wider:

A bit of calculating with DT’s Spoke Calculator and it was time to build:


Too short spokes, had to order new ones and wait until today. 2mm longer and much much better…

Hubs: Sram X0 boost

Rims: Ryde Trace22 29″

Spokes: 48 DT Revolution silver ( 16DT Competition on rear drive side)

Nipples: DT alu 12mm in blue

Result with tubeless tape:


50g more than planned with heavier hubs, rims and including tubeless tape I missed. But there is something with silver spokes.

Now just waiting for saddle and handlebar before I can finish and start riding for real. Looking forward 🙂

Blue Lightning #6

The 2nd part I ordered for my bike was a fork. Thought of getting a new Rock Shox SID WC but when I saw real weights and price I went for a Fox 32 Step Cast instead, lighter and cheaper 🙂


Got some new matching stickers too, maybe the part in this build I’m most excited about. Really love how they shaved of weight and optimized.

So what about weight, Fox say 1,38kg and R2-bike confirmed. Out of the box it was 1399g, cut in right length with a starnut and axle it’s a bit lighter 😀


Blue Lightning #5

If I would have aimed this to be a superbuild I would have went for a Epic FSR or an Camber. My first plan was to build a cheap but good hardtail to ride with my friends. Then one part after another got changed 😉 but price is always a factor and good quality. Instead of Tune King/Kong or the new Acros Nineteen XC Boost I went with a matching pair of Sram XO:


Regular Sram 10-speed body and 110/148 wide Boost hubs


Front hub came with Torque Caps but I’m not sure they work with my Fox fork and saved 5g with regular endcaps


Will be laced with some silver DT spokes 🙂 More on that after the weekend when the rims arrive.

Blue Lightning #4 the heart


Specialized said 1175g for the new Specialized Epic Hardtail Fact10 frame. Jaime thought 1228g and I thought 1250g as it feels like it’s always heavier than they say. Really happy to see the 1115g including wireguide, bottle cage bolts and derailleur hanger:


As it’s Boost on this frame I thought the axle should be a bit heavier than a regular 142 axle, but it’s lighter 😀


Everything seems to be getting according to plan and now everything is ordered soon the spring is here 😀 Will be Epic :p

Blue Lightning #2


The blog maybe seem a bit dead but the project is going forward. slowly but forward. When I came home from work I had a Sram X0 Short Cage Type 2 derailleur hanging on my doorhandle 🙂 Great with friends and good messengers.

To compare with newer derailleurs made for more gears Sram XX1 is 241g and Sram XX1 Eagle is 265g. And thinking of lighten my X0 a little more 😉

More to come soon…

Blue Lightning #1

a.k.a Specialized Epic HT Cerrol Edition.

On my earlier light mtbbuilds I’ve been using Sram X.0/XX1/XX1, Cannondale Hollowgram SL and KCNC cranksets.

On this new build I will try a ”new” crankset, an old Specialized S-works that seems really light, lightest mtb crankset I had:


With a 34t oval chainring from Garbaruk and probably all spacers I need.

It won’t be the lightest bottom bracket I had as BB30 is lighter but this PF30 bottom bracket is the lightest I’ve found:


Now on instead of just Ride Reports I will post some weightweenie stuff too 🙂

4 weeks to Christmas

In Sweden we got Advent. 4 sundays before Christmas and today was the first. The weekend Christmas starts with decorations and the waiting. Advent means waiting.

And I’m also waiting for a new mtb. But it’s getting closer and last part I got now is a cassette. Sram XX 11-36:


50g lighter than XX1, 143g lighter than XX1 Eagle. Sure, this got a gear or two less but do you really need that?

Shaving weight is about just use what you need. And I don’t need a bigger cassette than 36, specially not when I’m aiming to build a bike at 8kg 🙂
