Yakima Rack Pictures; why and how would this be hard on carbon frames?

Compared to metallic frame materials, carbon frames are much less tolerant of the type of loads applied by a rack. (Thin wall alum doesn't do well either.) Carbon frames are strong with respect to the normal stresses of riding, but weak with respect to the odd localized loads exerted by the attachment points of a rack and clamping. This is the reason virtually all mfgs of carbon frames strongly advise against using any sort of rack that clamps to the frame tubes. It's also the reason you should never clamp a carbon frame in a bike repair stand.

I'm sure many carbon frames are put in racks and survive (being gentle with clamps and spreading the load with padding helps a lot) but it's just not a good idea. The frame in a rack needs to see the same sort of loads it sees while riding - through the wheels, the dropouts, etc.

Those straps and tray will rub the paint off the top tube from shaking around during transport.

Again...tray racks are better. Bike is supported by wheels and clamping is done on the wheels.

Just a quick note on a couple minor problems withy my 2019 Carbon Comp X. I took it in for it's 30-day new-bike tuneup at the LBS and asked that they look at an annoying light rattling noise in the area of the steering-head/Future-Shock. The mechanic noticed that the Future-Shock cover (the plastic cover that turns with the handlebars) didn't fit tightly and later diagnosed that the problem was that they had fit the wrong part at the factory. The proper cover fixed the issue. The mechanic also noted that my bottom bracket bearings weren't turning smoothly so they put a new Shimano BB on the bike. (Nice that these new Sirrus models have a standard threaded BSA BB that takes an everyday Hollowtech II rather than some fancy press-in model.)

Anyway, if you have a a new Sirrus with the Future-Shock and notice a rattling in the front end, you know here to look.

The bike is building miles quickly. Really enjoy riding it.

Have you done much gravel riding with it?

Mark, thanks for earlier emailing me closeup of your paint, I ordered the Purple and should see it this Friday.
Thanks for the info you just shared, I will share this with my 1-man LBS, he is expecting the recall repair part to ship with the bike.
Curious, did your LBS cover that Shimano BB, if not how much? Is it of significant better quality, if so I might just put it in now, I remember the BSA BB was something that caught my eye on this model months ago.

(OT: I also bought a Roll compX1 as a "beater" companion bike to my Sirrus, having fun riding that today)

Far as I know, your bike should actually ship with the new FS collar installed. I have the same bike on order; lbs tells me that all FS bikes shipped since mid-January have the 'fix' in place. If not, my lbs has a bag of them in stock.

BTW, I'm planning the same thing re. b/b: when my bike (finally) arrives, I'm having a Shimano b/b (9100) installed before I take it out the door, and brake rotors upp'd to Shimano Ice Tech (XT).

Wow Mark, THANKS for that info. First you just saved me 150$, I was going to get a repair stand, I had no idea they are not allowed in repair stands.
I hope this is common knowledge and my LBS doesnt look at me sideways when I ask him not to build my bike using a repair stand.
So glad I joined up in this community!

Midway I am going to sell my rack, mine, only a few years old, has the same miserable rubber straps as yours.
Im selling it and hope my Uhaul installed tow hitch doesn't cause any problems to my 2014 civic, and speaking of that car, it has big area after rear fold down, just have to release the wheel
I also have an Audi A4 wagon (2002) and a GMC Sierra truck available to borrow at any time. At least it will fit inside your Land Cruiser.

Pretty much this. It was standard practice even before crabon to never clamp a frame tube, especially a top tube as thin steel and Al dent easily. There is a wedged expandable seatpost insert that is used when the seatpost is removed.

There are also special racks. This one uses rubber donuts and straps (long gone) to secure the frame:

No charge on the BB changeover (as I expected). I have no idea of the make/model of the original, but the replacement is a Shimano BB-RS500 which is low-end on the Shimano BB pecking order, although I'm sure it is completely serviceable and probably as good or better than what was in there originally. It's silver rather than black, but I don't care.

I clamp my carbon fat bike and carbon road bike in the bike stand on the top tube. Never had any problems. I'm not sure if this advice applies anymore to today's newer carbon frames.

I do clamp lightly though.

Proud owner of 2018 Sirrus Sport - disc brakes ; carbon forks.flat blue color..I'll add photo after reaching my 10 posts..
Rode the non-carbon forked model back to back in LBS parking lot and there was a noticeable difference in how much the
carbon front end could absorb....I'm 6'FT with 32" inseam and chose the XL frame over L...
Shifting is smooth enough and seat works for my short commute. Thinking about a rack and pannier .... any models work best on this
frame?
RE: bike stand issue- I use a Park PC-9 and hook my bikes up on their seat post...FWIW...

Anybody know what make/model crankset is on the X Comp Carbon? It has no obvious markings and doesn't look like any SRAM or Shimano model I can find. Specialized's specs simply say "Forged aluminum, 2-piece, 24mm spindle, direct-mount chainring". I'm curious as there seem to be multiple standards for direct-mount chainrings. The LBS mechanic who changed out my BB said it felt very stout but also fairly heavy. Probably an area where Specialized went cheap to hit their price point.

Hi everyone! I've got a question that's hopefully quick:

Are there paint codes for the colors that Specialized has done? I have a few chips in our bikes I'd like to take care of.

Thanks!

Specialized has been known to use Samox Cranks.

SAMOX

An image search doesn't turn up any Samox crank that looks exactly the same as my Sirrus one, but many have a similar style so I bet you're right. Thanks.

There isn't much discussion on the forum on pricing. Is it because it is prohibited or is it because it is standard across all retailers? Sorry I tried taking a look through the FAQs, but did not see anything on it.

Not much to discuss. At best your LBS might give you $200-$400 off the price of bike but don't count on it.

Specialized controls pricing of their bikes so typically the price you see online is the one you pay. As a result there's not much insight to share.

Thanks, that's good to know, so it is sort of like Rolex pricing.

Is this the standard across all popular bike brands or does it vary like watch brands?

It's more or less standard across the industry. Bike shops (or even brands) will sometimes offer sales on clearance models or otherwise throw in extras at purchase, but the purchase price of the bike itself is generally pretty consistent. As with every "general rule", I'm sure there are exceptions out there... :-)

It varies by bike shop. My local Specialized dealer lost a fat bike sale to me in 2015 because another shop 40 miles further away sold me the same bike for $400 less. Fast forward to 2018 and I was in the market for a new fat bike again. Went to my local Specialized dealer again and this time they knocked $300 off the price of the bike so I wouldn't go to the other shop 40 miles away and buy one again.

My local Cannondale/Giant dealer...continuously will knock $300-$500 off of new bikes. But the Giant dealer 40 miles away won't budge on price.

I've also worked dealers over on the phone or e-mail and got them to come down on price by having them match another dealers price.

Much like cars we shouldn't be paying MSRP for bikes. You need to haggle.

Some of these bike shops are short sighted in my opinion...The first step to earning someones business is to get their foot in the door spending at your shop. If you can sell them a bike then you get repeat business for service, parts, clothes etc. But some bike shop owners will stick to their guns on MSRP...that results in lost business.

Hrm, OK your posts are kind of confusing. I think if there's wiggle room from MSRP then there should be discussion around pricing. Other people seem to indicate that the Specialized price is the price.
