I changed frame from factor 1 to factor 2. Sometimes it was like nightmare but overall i finished my build

This looks very sharp!  I too am curious about the build issues you encountered and who you bought the frameset from.  (I have a V1 from First Class Carbon).  Lastly, please state what size frame this is!  (Sorry, personal pet-peeve of mine.)

I know there were some early comments in this thread about using a Deda compression plug instead of the one that comes with this frame. It looks like that product is no longer for sale from what I can see.

What are others doing for compression plugs? The one I received with the bike does not fit now that I’ve cut the steerer to size. Any other recommendations?

Hello rhenders,
Did you get this sorted?  I'm having the same issue - I've cut the steerer to length and now the stock compression plug top won't fit down into the steerer.  The options seem to be either take a little carbon out of the steerer OR take a little aluminium out of the top piece of the compression plug.  Since the compression plug isn't structural in the same way as the carbon, I'm leaning toward the latter, but I think either approach would work.  (We're talking about the very top ~3mm of carbon at the top of the steerer.)

Anyone else come across this issue?  I don't think the Deda plug would be any different (if you could get your hands on one anyway).  The issue really is that the carbon of the steerer is too thick.

Hey Team,
Trying to get my ducks in a row to put my ostro together.  Of the parts that F-C included with my frameset, this piece (red circled) was not included.  I asked F-C about this and the response was "The front fork is a new model; this accessory is not needed."

Really???  Anyone here built your V1 without this 'spacer'?

Hello - I have a ostro vam and it looks like the handlebars is developing a crack - any suggestions on where I can get a decent replacement - v1

AliExpress is chock-full of one-piece CF cockpits.  There are posts on this forum with recommendations (good and bad) on various brands.  I'd say the replica Black Inc bars that came with my v1 frameset are of decent quality, but I haven't even built the bike yet, so take that with a whole shaker of salt.  (See First Class Carbon store on AliExpress.)

Sorry this isn't much help but it would be good to know what exactly you're looking for.

Glad your frame actually showed up. I didn't see any issues with the handlebars right down to the matching v1 off color screws to match. ...

Hey jerozilla.  Regarding the bars, I did try to slip them onto the steerer tube but found that I had to use a lot of force, either because the clamp is too small or the steerer tube is slightly oversized.  I only got about 10-15mm before giving up. (I was just playing around anyway.)

I'll investigate further but has anyone else seen this?  What's the recommended fix?

And regarding rotor size: are you running a 160 or 140 on the rear?  I'm assuming 160 on the front.

Thanks

What makes you think it would be p505 compatible?

I'm not familiar with the "easton mounting standard".  The Magene P505 PM spider is round and has four mounting bolts, not unlike those pictured in this thread (which are apparently compatible).  raisinberry777 set me straight.  I'm just not that into my p505.  I thought having a PM would be the final frontier, but the p505 added 100g+ to my bike, and the data isn't *that* useful.

Hey Team.

Update on my Ostro frameset as purchased from F-C:
Last Saturday morning, I took one last desperate look at my tracking info only to discover that my frameset had been handed off to US Customs in L.A. California just after midnight early that same day.
On Thursday, I picked the frame up from the local USPS office.  I thought they might ask for tariff $$$, but they didn't.  The box was somewhat battered from 76 days in transit, but the contents seem to have survived the trip.  The quality is what we've come to expect from F-C.  The BB facing seems fine while the caliper mounts aren't pretty but I think they're workable.  The quality of the bar/stem is o.k. - definitely not as good as the frame.  In particular, I asked for 380/100 and they are marked as such, but I don't really see how they measures out as 380/100.  Still, the bars will work for now at least.

Anyway, I wanted to update this thread.  In the end, I got my F-C frame after approximately 90 days, from order to delivery.  F-C certainly has areas to improve their customer service, and I think Aliexpress is equally to blame.  The shipping is overpriced for absolute sh!t quality.  I've never had a worse shipping experience, and I've purchased a lot of rare/odd auto and bike parts over the years.

I'll post pics of my build as it comes along.  I won't be rushing through it and will likely need to ask some [dumb] questions.

Cheers

ttgolf - Did you try your tracking number on USPS.com?
