I would also happily rock one fixed.

this is not true. the rear spacing on the disc is 135mm and always has been. the rear on the rim brake NB has always been 130mm. all city makes 130mm spaced track hubs.

Went and took a new rider class a my local velodrome and was immediately hooked. Needless to say, I need a new bike now. Wanting to get a light and stiff aluminum frame to go along with my Fuji Feather for around town. Looking to buy a complete bike and swap my Omniums over to actually get the benefits out of them. Considering buying an Aventon model bike since it won't break the bank. Any opinions on the new versus old style Cordoba? I've heard the older model is actually stiffer with the way the seat stays meet the seat tube lower.

Also, I rode a 56cm Windsor The Hour for the class, and it felt huge. My current bike is a 54, but I'm sporting risers on it. Should I be looking at getting a 52 or a 55?

Word. I just knew they weren't 120. :thumb:

Going to be getting an All City Natureboy Disc frameset to build up. I've got some 75s at my disposal, and am tossing around the idea of running it fixed. With the Surly Ultra New fixed disc hub the chainline comes to 53.5mm, whereas the 75s on a 109mm BB come to 42mm. If my math checks out, I'd need a 132mm BB in order to use them.

Is this even a feasible thing to try? Common sense is telling me no and I wouldn't be heartbroken, more just wondering if it's even a possibility.

Doubling on this question, will 75s actually work on a NB Disc? I know they'll fit on the 120 spaced NB, but have no idea if there's enough chainstay clearance for them on the disc version. If there is, I'll probably do SS with them and use a standard mtb freehub wheel to get the correct chainline.

Where will you be finding a bottom bracket having a 132mm ISO spindle? :foo:

Mark Ainslie came by the shop a few times last week and gave us an update. Supposedly the new contractor is doing a really good job and it will be finished in time for track season.

I took one for a ride when we first got them and the new cordoba LTD feels stiffer. Less flex near the BB shell because of the new outward-flaring seat tube.

I can't realistically recommend a size over the internet. If your current bike fits you, compare the Aventon geo chart to your top tube length. If not, use a fit calculator.

jacobsever 03-13-17 03:06 PM

Haven't been on here in a long time, and didn't see anything via search function (sorry if it's been asked).

Does the 2017 Vigorelli come drilled for a front fork? And do you know when the release/street dates for them are?

Scrodzilla 03-13-17 03:14 PM

Drilled and plugged, Like all Cinelli carbon track forks.

According to the ETA we got when the shop pre-ordered them, they were supposed to be here two weeks ago. I'm sure they'll be along soon.

Well, Phil Wood offers ISO spindles in 130mm and 135mm lengths. And the Phil mounting system allows several millimeters of lateral adjustment. So, if the OP is willing to cough up the $$$ for Phil Wood, it could be done… :innocent:

Phil Wood & Co.

Scrodzilla 03-14-17 11:09 AM

Yeah, I always forget that Phil Wood makes spindles in some wacky lengths. Seems like the potential added flex from using a spindle that long defeats the purpose of using stiff Sugino 75s, but it's not my bike...

You're not wrong of course, technically, but how many people are really using them primarily for (or benefitting at all from) their stiffness in the first place? 75s just look ******. :p

What happened to Pake? Their website is gone.
And will Affinity ever make more frames?

I'm getting a killer deal on a Giant Omnium frameset from a dude at the track. I have everything to piece it together except for a wheelset. Any recommendations for a strong wheelset that is relatively light? I won't be doing a whole lot of standing starts with it, so I don't think I need something that's laced 32.

Was considering the LA30 wheelset, as I hear they're pretty close to Ellipse wheels, but don't know how dependable the 8mm bolt on hubs are going to be.

They won't be a problem.

Yeah, more of a -can it be done- sorta thought.

Needless to say, I'm not going to be trying out after a few nights of cruising the net. No fixed NB disc for me with my current part outfit. At least SS will be far easier to get sorted.

According to conversations we had with a source at Somafab a few weeks ago, the future of Pake is uncertain.

Affinity is a little weird to deal with. We've been hearing about a re-stock for nearly a year now. It's is a one-man show and I'm not sure if Jason is doing too many other things or what...

Deathoftheparty 03-16-17 10:18 PM

Any idea what the specs are on the LA30s? Really contemplating pulling the trigger, but just trying to identify who makes the parts? Hubs/spokes/rims. I think I remember seeing Kinlin for the rims, and Novatec for the hubs, but I'm not too sure.

Scrodzilla 03-17-17 02:15 AM

I'm not really supposed to disclose those details, but you may have answered your own question. ;)

JeremyLC 03-21-17 08:37 AM

What torque wrench do you use around the shop?

Scrodzilla 03-21-17 09:09 AM

My hands and my brain.

If I do need to occasionally bust out a torque driver, it's an old reliable Snap On my dad gave about 20 years ago.

JeremyLC 03-21-17 09:17 AM

I'm usually fine with metal parts, but I'm a bit worried about crushing or cracking my CF handlebars and steer tube.

Scrodzilla 03-21-17 09:51 AM

A good rule of thumb if you don't have a torque wrench is: if the bolts are tight enough to prevent the part from moving, they're tight enough.

calamarichris 03-29-17 02:28 PM

S'up, Flyguy? What is the highest kgf you'd go on these Araya SA-30 rims?

calamarichris 03-31-17 01:40 PM

Do I win a prize for stumping you, Scrod? :)

What's the maximum spoke tightness in Kgf you'd recommend for those Araya SA-30's I bought from you?

Even Google appears not to know on this one. Do you think 120kgf is pretty safe? Can I go slightly tighter on the rear, since both are technically drive-sides?

Am hoping I can get down there this weekend or next week to take a look at them stems.

primo123 04-02-17 07:46 PM

What would be the factory reAR spacing on a 1984 trek 610? 126mm 6 speed?

fixieluvr 04-06-17 01:30 PM

Can you recommend a 44t or 46t 3/32" 130 bcd chainring replacement for my SRAM S300 crankset? Can't find one on retro-gression

Scrodzilla 04-07-17 11:32 AM

Holy crap, has it really been six years?

While I’ve really enjoyed having you guys ask all kinds of questions ranging from silly to technical, the shop has become far too busy and takes up way too much of my time to keep up with forum stuff. The real questions seem to be coming less often these days and most times people are just asking about stuff my shop sells. I also feel that a few people who were asking me questions a not long ago are now able to answer a lot of this stuff on their own so it’s a good time to bring down the curtain.

I’m super glad to have been able to help so many of you when you’re stuck trying to figure something out but here’s the thing - I learned everything I know by researching things myself and getting my hands dirty. I was a confused noob once too and certainly wasn’t born having a long grey beard and the ability to build wheels in my sleep. It’s totally ok to **** something up, learn from your mistake and do it right the next time. They’re only bikes, after all…

In all sincerity, I have such incredible appreciation for the support Retrogression has gotten on BFSSFG from the early days in our 250 sq-ft, centipede-infested basement shop in Beverly, MA to what we’ve become in San Diego. It’s been a long time, a long journey, a lot of hard work and our passion for track bikes only continues to grow (despite the nay-sayers who claim the scene is dead).

If anyone misses me, I’m always easy to reach by email and will still drop by the forum from time to time to ruffle some feathers.

¡Adois, amigos! :D
