Rocky Mountain people: Where would I look on a 2019 Altitude frame to find the size? I'm probably picking one up for my kid tonight. The seller thinks it's an XS but doesn't seem to be 100% sure and can't seem to find a sticker on the frame.

Dan, Headtube is historically the easiest way to determine frame size with a tape measure. It's how the shop manager at BC does it with any issues on mis-labeled frames from brands. Should be 100mm from what I can find on both a 2018 and 2019 PB articles about the altitude.

[Dantheman]

Awesome, thanks. Rocky's archive page says 100 mm as well (https://resources.bikes.com/en/bikes/altitude/2019) and the seller confirmed that's how it measures out.

The bike has a 27.2 post diameter, also I'm too cheap and don't want to put too much $$ into this bike I plan on selling at some point. I don't have any problem on most of the trails I ride highposting. I just want to take the edge off for long rides.

If you're looking to keep it simple, it sounds like you're the perfect candidate for a Ti layback post, esp. with the 27.2 diam. I ran my SS that way for years, with it set at just less than full leg extension so I could get behind the saddle for steeps. It was an old-style Moots (w/ the PITA clamp), and it really did take the edge off (along with the biggest tire that'd fit the stays). Not as smooth as a Thudbuster or similar, but also not as heavy, and it looked way more tidy. No idea if the Chinese posts would be the same WRT tubing gauge and compliance, but I'd think it'd be a very similar experience. That said, I run a dropper on my SS now and am rarely tempted to go back, so there's that.

If the stock cassette is a Sunrace 11-42, the 11T small cog makes me think that might be a Shimano HG freehub body.

Thanks for that, I just figured it was SRAM and whatnot. What options do I have? Will the 10-46 work? Or I could run 11-44 if I had to.

The serial number also has the size in it before the last 4/5 numbers.

11t means that its a HG freehub. None of the 10s cassettes will work.

I've given up on finding a FS bike this year and decided to stick with my hardtail for the time being. I want to do what I can to make the hardtail suck less on rough terrain, and I'm thinking about getting a titanium seatpost for increased compliance. Tough to stomach the $250 cost of name brand, has anyone bought a Ti post from a chinese manufacturer on ebay? Looking at something like this https://www.ebay.com/itm/12343430693...gAAOSw~llcB3or

The seat clamp probably isn't the same quality as the name brands, but are there any other functional differences?

PNW makes the best 27.2mm dropper post going, IMO. Do it.

Fuck the rigid post.

2nd I have the Coast suspension dropper on my gravel bike, makes it so much smoother as well as fun offroad.

follow up

appreciate help with Q1, new round rings and chain are on their way, will flip cogs and see how that goes before throwing more $ at things

could still use input on Q2, cross strap just split 3/4 across and shoes are telling me its time to be put to pasture
trainer shoes, thoughts?

I have super narrow, low-volume feet too, and the only shoes that really work for me are Sidis. You could try Giros, which are pretty narrow in the scheme of things, but they probably won't conform to your foot as nicely. They might work fine for the trainer, though, where you could give up a bit of precision.

Okay, thanks for that. The bike will have a rival 1, 11 speed, long cage rear mech with a 40t chainring. What’s the max size cassette I can get on it? I can make it work with 11-42 but would prefer 11-44, and I want it to be light! What am I looking for?

Sunrace makes an 11-46 11-speed cassette, which I have on a mountain bike, and it's decent. I don't know if there are any issues with using it on a Rival road setup though.

Its rated for 42T rear, so a 44 (or even a 46 should...) would be fine, just make sure your B-Tension adjusted enough so your jockey wheel is far enough away from the cassette to not rub.
11 Speed options are mostly:
11-42 in Shimano XT (434g) or SLX (476g) (jumps are 32, 37, 42)
11-46 in Shimano XT (437g) or SLX (482g) (jumps are 32,37, 46, yuck)
SRAM 1130 11-42 (538g!!!!).
Sunrace S7 11-42 (471g)
Sunrace S7 11-46 (507g)

The lightest option is a M9000 XTR 11-40 with the 17t and 19t removed and a OneUp 19t added with OneUp 45t 1st gear one the outside. Shifts are 35t, 40t, 45t. Not cheap but it's 395g! This is also doable with XT 11-40 (475g) and SLX 11-40 (515g)

[buttahflake]

Yes, thanks DH! So the Sunrace 11-42 isn’t quite the boat anchor I thought it would be, hmmm. New bike will be a couple of pounds lighter than my current rig. I’m going to see how it works as is.

[Falcon3]

Sunrace spec sheet is showing different weights?

CSMX8 11s 11-42 =401g
Steel 1-10 and aluminum 11th gear

CSMS8 11s 11-42= 465g
All steel gears

CSMS7 11s 11-42 = 507g
All steel.


https://www.sunrace.com/files/catalo...2011-Speed.pdf

This review of the CSMX8 clocked that 11-42 at 419g (a little more than the stated 401g).

[buttahflake]

You guys are the best!

[Dee Hubbs]

That Sunrace CSMX8 11sp 11-42 @ 419g or 11-46 @ 465g is a only a few bucks cheaper than comparable weight Shimano M8000 XT.

Is there a summer version of the below? IIRC there were some enduro baggy bib shorts, but I am not finding them.

I love how the DH & endurbro crowd is making their shorts/pants tighter and tighter because, let's face it, tight clothes work really well for cycling. Huh. Maybe there's something to Lycra after all.

The same thing is happening with bikepacking. They went nuts with bags strapped everywhere, but those bags swayed around crazily and were difficult to pack. The newest trend is to create structures on the front and back of the bike that bags attach to. (But don't call them racks!)

What comes around goes around.

DH racers are pretty much wearing skin suits again albeit with padding underneath

[Shredhead]

Wave I’m almost at the yop

[Andeh]

Meanwhile all us guys who enjoy a post ride beer or just have dad-bods still do a hard pass on these trendy new skinsuits.

Pretty soon disc wheels on DH bikes will be back, and they’ll have to revive the Kamikaze DH.

[GeorgiaSnow]

As a proud owner of a dad bod I’m thoroughly enjoying the latest posts in this thread. For years I joined in the judgement of the Lycra crowd. Recent forays into road biking have helped me see the real insecurity behind those opinions.

I wore my waterproof baggies riding today and forgot how awesome they are. If you ever math in the rain you should buy some.
