Sorry to hijack your post, but any chance you could look out for the new stem for me. Tried several attempts through the wensite, never got any response at all.

Fredly, I am trying to build out the andean frameset I bought and not sure what size dub pressfit 30 BB I need to buy for this frame. and help would be greatly appreciated.

Howdy,
The Andean uses a PF30 BB, all other specs are dependent on the crank, and your best source for those requirements will probably be the manufacturer of the crank.

FWIW, in the past SRAM BBs have tended to run slightly large relative to most manufacturers (although I haven't measured the DUB units) and people generally had better luck using SRAM compatible BBs from other manufacturers rather than the SRAM units themselves on the Andean. YMMV.

Fredly do you know the frame shell width @ bb. The sram dub pf30 bb comes in widths 68, 79, 83. I think it is 68 but not sure which to order.
Sorry for all the questions but thanks for the help.

It's 68mm. All PF30 road frames are 68mm. Those other sizes are BBright and 386 EVO.

What’s the maximum chainring size for the Andean? I’m still planning out my build, but am considering Osymetric chainrings which are 58t (iirc) on the power phase.

The chainring fairing on the Andean has a 125mm radius, you won't be able to fit any chainring that exceeds that measure with a chain installed. With non-round chainrings, you will definitely want to measure to be sure.

Aside from oval chainrings, what’s the biggest round (shimano) chainring that’ll fit? - cant Seem to find any diameter specs on chainrings anywhere

A round 53 tooth chainring with chain installed, has a diameter of about 222mm.

How big do you want to go?

I’m considering a 55/42 set or Aerocoach 54/40

I ran a 55/42 when I used to race on the Andean and had no clearance issues.

A 55 tooth chainring should fit easily.

A round 55t chainring will easily fit inside the chainring cutout on the Andean. Anything that fits inside the profile of a standard round 56t ring should work just fine.

Thanks for that.
Frameset arrived today, so I’m just doing a quick parts in the boxes in their place assembly. Seems easy enough, aside from annoyingly Small 2,5mm hex heads (my ratchet wrench only goes down to 3mm).
However, how on Earth do I get the flappy cover for the “storage” fairing behind the seatpost to play nice a sit snug?

Don't install the cover by pushing it straight down into the fairing. There's a subtle taper in the width of the cover from front (of bike) edge to trailing edge. Insert the trailing end of the cover into the fairing about 1/2 way towards the front of the opening, and then slide/push it towards the trailing end of the bike.

That did work, however still pretty slow to open close. Considering 3D printning a plastic cover instead.
The frameset doesn’t Seem to include a dust cover for the top headset bearing, it that a mistake? - or are the spacers/bottom stem plastic cover supposed to function as a dust cover?
A few other notes for anyone building the frameset - di2 grommet for FD doesn’t actually fit in the hole in the frame (hole is round, grommet is oval, had some shimano grommet in the spares box, they work fine.
The Seat stay insert for RD cable didn’t fit in the cutout - cutout too small, had a rubber grommet from a China frame that fit. Storage space door Can’t close properly, because a plastic rivet isn’t pressed in hard enough. Probably just going to sand it Down and add a magnet to keep it shut. In general the assembly instructions are good, however a few things are missing - what are the bolts for, most of them are obvious, But not all, How to actually fit the top tube storage and some on the hex sizes are wrong. Now, I’m going to fit the PD Aeria Ultimate bar and stem (and hydration), But with the included stem and top/bottom cover, it’s more or less impossible to use a torque wrench On the stem bolts - you would need a long one. Most of the bolts are 2,5mm hex and a 2,5mm hex bit isn’t a part of the included torque wrench - wouldn’t have been a problem if the Tool hadn’t been included. But it seems Odd that the size you need the most isn’t there, But something else is.
While the battery Mount in the crank storage is a fantastic idea, it’s seriously fiddly unless you add 5-10cm to the min cable length for di2 (used spares off an old bike, so not a problem, just had to put the b junction near the BB) . Still waiting for parts to come home to do a trainer fit, But in general i’m happy about it. Seatpost on a size large is a bit long, min Seat height at zero offset with ism Adamo saddle is 84cm, which is too much for me (6’ tall). And there’s no torque spec for the Seat rail to Seat post in the manual - tried 5nm, Will have to wait and see if that’s enough. From all if the above, built quality feels like a Chinese open mould frameset, had I payed full retail, I would have been disappointed, But I didn’t pay much more than what an open mould frameset would cost me, so I’m happy about.
And it looks like batman’s bike

Is there any type of Slowtwitch discounts to be had on the remaining Andeans? I feel sorry for them just sitting there. :(

TIA,

Patti

Same as instructed in this thread, as far as I Can see.
Andean 3 is $6500, Andean 2 $5000, 2019 frameset $2399.99

I pulled the trigger and an Andean 3 and have to say I'm really happy with fredly's support and the guys at diamondback who answered a lot of questions for me.

Now its here in the box and I'm thinking about trainer season. I have a lovely computrainer (the 2014-ish model with USB) and thinking - "will it support thru-axles?

Any thoughts? I know I can get the right axles for trainers on the Robert Axle Project but will the computrainer cups accommodate it?

Also, for anyone on the east coast of canada, can you recommend a good mechanic or fitter? Travelling back to Toronto is not an option these days. Planning on staying in our relatively safe COVID bubble.

Thanks all

Rob (Halfcrazy)

As a owner I can warn you not to use it on a trainer. The frame flexes way too much then what is good for a frame when you put some serious efforts on it. I had it on a Kickr, but took it of after a few sessions.

As long as the frame of the trainer has enough space to accommodate the frame (thru axle dropout spacing is wider than QR spacing) you should be fine with the appropriate adapter axle. I haven't actually put an Andean in a computrainer, though, so can't report as to whether it does have enough width.

There have been *a lot* of trainer miles put on Andeans since they came out, and at the time I left the company there had been zero trainer related failures or issues reported.

The way that a trainer interacts with a frame *is* much different from how a frame reacts to pedaling on the road, so I would recommend against using any bike/frame that you care about extensively on the trainer. I say this having just repaired the drive side dropout on my own trainer bike after I broke the seatstay clean off.

I'd make note of this particularly in relation to Jeroen's comments about frame movement of the Andean on the trainer. Yes, framesets that are designed without seatstays will typically exhibit more visible flex when mounted on a trainer. The forces that cause that movement are, of course, also present in trainer use of frames with seatstays, but the visual manifestation of the forces in action is constrained by the seatstays, which probably aren't designed to withstand those forces over the long term. It's pretty rare to see seatstays fail on frames in "normal" use, but I've personally had three of them fail on trainer bikes over the years.

FWIW, when I worked for a trainer manufacturer back in the day we did a reasonably in depth analysis of the loads encountered by a bicycle frame when it is mounted on a trainer. We found that getting on/off the bike generated the largest (and most likely damaging) lateral force(s), and by a fairly substantial margin. It is a very good practice to minimize these loads. Avoid clipping in to one pedal, and then swinging your leg over to the other side of the bike to mount the bike.

This is all true. And I’m not saying that the frame got damaged by using it in the trainer but the Andean frame in general due to missing the seatstays, at least mine and I didn’t ride it that much because I just own quite a few bikes, lost quite a bit of stiffness. The first year it felt really stable, but during the second year I began to notice much more instability on the rear of the bike. In cross winds more pronounced.
As well when using a disc in the rear. When I hold the saddle I can without putting real force flex the rear wheel 6 to 7 cm’s back and forth.

Of course most people just don’t have any trouble with it, And for sure it can be just me, but of all bikes I have the frame flex in the trainer was very noticeable so stopt riding it in the trainer.
But during the second season it also was there on the road.

Just didn’t like that feeling, but still own it and dig it. The looks are still amazing.

If your frame "lost stiffness", there is a delamination, a crack, or its a manifestation of observational bias.
If you can truly rule out the latter explanation, I would recommend taking steps to address the other possibilities.

...only other notable factor is wheel/axle choice, although it's pretty rare to find thru axle wheels/axles that are notably deficient in stiffness, but worth investigating.
