So I've come to realize that there isn't a thread just for Soma Juice/B-side/Riff pictures. If there is one, sorry for the repeat. If you've got some photos of a Soma Juice or B-side/Riff, I'd love to see them.

I just got my Juice built up and am actually quite excited to share.

I my excitement I left out much of the relevant detail. I wanted to build a XC race single speed bike that could be plus curious. I don't have much interest in the 29+ or All mountain platforms because of fit constraints. I started by building a 1x1 and found the steep head tube and horizontal to be limiting factors for my riding and convince . The Riff seemed to be a more thoughtful execution for my goals. After much research I didn't find a whole lot of information and just decided to pull the trigger.

So far the updated more modern geometry is a welcome addition. I was surprised to find that the tire clearance seems to be notably larger. I like the Paragon drop outs much better because there is less fiddling and better retention. There is ample clearance for a variety of chain rings as well. Currently there is a 36t upfront and there is plenty of clearance.

Awesome looking riff! Hows the ride?

What fork and tire combo are you running?

-Edit: Whoops, I posted a reply before scrolling all the way down to see your second post.

Nice ride!

That is a very different type of build from the bike that I built up. Just shows how versatile these frames are!

Today I finally stopped by this temple that I pass each day on my commute. This is just the gate, I didn't take the time to go explore inside. There are lots of really beautiful temples and shrines just neatly tucked away all over the city. Many of them are seemingly unknown to most tourists and are therefore not very crowded.

It amazes me at how much history there is here. Just the other day the family and I went to Ueno park and stopped by the zoo there. Just so happens that there are the remains of a teahouse that was used to entertain shoguns as well as a pagoda from the 17th century just right there in the zoo.

Sadly, there have been no real dirt trails for this bike yet. I've been so busy with work and family and with no car I'd have to take the train to get to the mountains which is like 2 to 3 hours of travel time just to get there.

This summer, that's the goal. Take a whole day for myself and head out to some real trails.

For now I've been satisfying my dirt inklings by roaming through one very rare vacant dirt lot near my apartment as well as a dirt pathway near a construction zone on the way home. Sad I know, lol.

So far I far there are two things that I notice most about this build are the more modern geo 69°. Although it's relatively conservative now a days for race xc in the flat mid west it feels about right. The other thing I notice is the larger tires 2.4 feels wide by comparison to the 2.1's & 2.2's I am use too. With the tires at 16psi I can't claim to be able to test the frame stiffness. I am underwhelmed by both recon forks lack of dampening and the frames mediocre weld quality (judged by aesthetics).
