I just got a 2019 S-Works Tarmac SL6 off ebay. I expected an "OSBB" but it has a BSA. I was planning on pulling most everything off my "classic" Venge but I guess I can't use my S-Works crank, so now I need a new crankset too... What's the deal with "DUB"?

I also need direct mount brakes. I'll probably just get some EE's, change my mind.

Nokons seem to be unobtanium now.

And finally, does anyone make -17 degree stems anymore?

Dub is a sram standard, their original 2-piece design was 22mm/24mm while shimano's was a straight 24mm, dub is a straight 28.9mm that allows for better bearing size and sealing in an english thread bb without giving up too much of the stiffness that a 30mm spindle offered.

Profile still makes -17

I think I'm going to call Specialized in the morning and see if they can tell me if that frame was supposed to have an OSBB/BB30 shell or BSA threads. Maybe there's just an insert wedged in there really well. I don't want to start banging on anything if it's permanently bonded in though.

If I have to stick with the BSA though, I was looking at a BBInfinite since it looks like it can do BB30 or DUB.

Specialized itself offers a 17 degree stem:

You can install it upside down.

Annoyingly, I could not find any documentation or discussion on how Specialized measures their stems (extension vs. reach, etc.). I probably could have dug up some old ones to see what they state vs actual, but I decided to just order the same stuff as my Venge. I order Zipp Service Course SL (120mm +/-17deg), and Zipp Carbon SL-70 Aero (40cm C-C).

For "just get a new frame and swap everything over", this is getting to be a lot more than I had originally planned in my head. BUT I decided I wanted to leave the cockpit intact to make it easier to rebuild later.

Build so far:
2019 S-Works Tarmac SL6 Frameset, in Gloss Chameleon/Cyan Blue
0-offset seatpost
Zipp Service Course SL stem
Zipp Carbon SL-70 Aero bars
Fizik Arione R1 Saddle
eeBrakes, direct mount
Red AXS D1 DUB 12-Speed Double Crankset

I'm "borrowing" the following from my Venge:
SRAM Red eTap 11sp w/A2 RD
Reynolds DV46T

I ended up going with Jagwire links instead of Nokon. Mostly because I could get it in blue (I sense a theme...).

Late to the party.

Bontrager pro stem comes in 17 degree. 128 grams 100mm and and and only $120.00

Ask me how I know.

ummed

How do you know?

ummed

The Zipp stem is also $120 but I got it on sale for $90.

I'll pretend I never saw this email...

bampilot06

I ordered one for the 5200 trek.


I wanted the enve aero stem, but the enve stem weighs about 60 grams more, and I just can’t get past the bontrager blendr system. It works awesome, and all my bikes have them. Anyways, zipp sprint is cool too.

bampilot06

As low as 22.95 if you want 46 cm bars

ummed

The Zipp sprint is actually not available in 17, only 12. I'm not a sprinter anyway

bampilot06

Thats what I said.

ummed

Yeah lol, but I could have gotten my stem for that price. They only had the bars in 44, or I would have returned the ones I got from Biketiresdirect, and bought them from there (Planet Cyclery) instead.

ummed

Despite the "extralite" top cap, I'm not really going for an ultra lightweight build. That's just fashion, I have it color-matched on all my bikes. I would assume it will be the same 15lb ballpark as my Venge. I'm way past caring about a few grams here or there.

bampilot06

If it makes you feel better, I started caring too late. 3 of my bikes are in the 18 pound range, the old ass trek might 16 not sure. Now if I need to replace a part I try and go as light as possible. Maybe one day all of my bikes will be 15 pounds. They will probably all be different bikes than I have now, but 15 pounds.

ummed

I usually go the other way. For example, I only spring for the super-light cassette when the bike is new. What do you mean these things wear out? $400 for a new one?!? f-that!

edit: I would say it's not that hard to hit 15lbs, but I also just spent nearly $5k and I'm not even getting all new stuff

edit 2: I think I had my old Tarmac SL2 down to around 13lbs at some point.

ummed

Well, that's interesting. I've put the parts I've gotten so far together and have sort of a "rolling chassis", that's at 8lbs nearly dead even. Adding up the claimed weights of the rest of the components on order, plus the ones I'm moving over is another ~5.5lbs, for about 13.5 total. I don't think I've forgotten anything.

ummed

Pedals. I forgot pedals

bampilot06

not important.

There are light and durable cassettes that do not cost nearly that much: Prestacycle UniBlock Cassette | 11-Speed Shimano / SRAM /Campagnolo for HG 11 Freehub - Prestacycle

I paid $169 for each of my 12-28 and $107 for my 11-34.

It was only really a problem for me in the past with the Red 10sp stuff. Between many different wheels with different gearing and piles of miles, the Red 1090's got expensive fast, even though I was usually able to find good prices.

Since I switched to 11sp I don't ride enough to wear stuff out

I still have the "original" XG-1190s on both 11sp bikes.

ummed

Well I couldn't resist the 40% discount on the Quarq version of the SRAM Red crank.

ummed

Finished last night and rode it today. Came in right at 14.5* after adding the Quarq and, um..., pedals.
