Really nice, is there good clearance between the chainstay and the chainring if you want to go with bigger chainring like 60+ ?

m@tty

I don’t have any chainrings that size to try but there looks to be enough clearance for 60+ using my maths which might not be correct? there appears to be about 25mm extra radius clearance at the chainstay with a 53T on so that would equate to 50mm extra diameter and each tooth increases diameter by roughly 4mm
So 50/4 = 12.5 and 53+12 = 65 so you might squeeze a 65T on but anything more might require spacing.

It looks fast!! really nice bike!
Front wheel brand? I have the same rear disc, and I'm searching a front wheel.

Not sure if this applies here, but I have dug this out of my storage unit. Bought it from a nice guy overseas who is/was a member here with the parts to go with it. I didn't find any info on this forum. I will post it completed in the C&V section.

Edit: sorry I didn't acknowledge the "(2014+)" category!

Nice. And a cool head badge too!

good luck with the build.

Oh sorry just looking back through this thread just realized it's current racing rigs - which is a pretty kewl idea - wasn't trying to step on that - I do dig old track bikes but I see too now - not the focus here. Peace n love

Went from a 130mm to 140mm stem today...the 140 is +/- 6º while the 130 was +/- 10º. I know there is a calculator somewhere to compare the angle, stem length, and actual reach...I'm pretty sure I'm not getting the true extra cm from the 140.

If you want more reach you could start by putting your hands all the way into the hooks?

brian44

Thanks for the suggestion! I wonder what I would do I still wanted more reach while in that one specific position as well.

Baby Puke

I've heard legends of 15cm stems, but never actually seen one in the wild. Part of the problem is that modern bars have really short reach compared to old-school sprint bars, which have way too much drop for kids these days. A good compromise, if you can find one, is the 33cm Alpina bar. Not too much drop, but generous reach. I have wanted one for many years now. Also tilting your bars up effectively lengthens the reach. The bottom of my drops are probably at around 7˚ or so for that reason.

seen these bad boys?

There is a "long stem" movement that seems to be present in some track cycling circles (Velobike comes to mind) with some offerings from 150mm to 200mm, stem lengths. I think that is extreme, but for someone who (a) doesn't want to (or can't) change bars; (b) TT length (effectively frame size); or (c) only wants to drop $50.00 on a used stem and see how that goes...I think going a tad longer in the stem department is a reasonable option.

holy crap that stem is almost $400

I know it only has to turn left, but man, handling must be a dream on a 150+mm stem

Baby Puke

Actually yeah, I just saw these, the 115mm reach version could be a big problem solver for a lot of people.

Baby Puke

Yeah, plus if you are running "big races" you will eventually run into problems with the UCI rules on bike set-up if you have a crazy long stem. Longer top tube is still the best fix.

brian44

Good thing I'll most likely never have this problem

Baby Puke

You'd be surprised. Any kind of masters national race (not sure what country you're in) is likely run under UCI regs.

3T makes 150mm stems. But they are not available in the US. I had to order mine from the UK. If you keep an eye on it, they go on sale for about $40 pretty regularly.

brian44

As a newly minted 35-year-old...any reference to master's racing makes me feel weird inside (the truth hurts). Excuse me while I wipe my tears with my new 170 mm stem.

bicievino

I can only speak to since 2019, but US masters nationals hasn't required compliance with UCI geometry restrictions except for record attempts.
Not that that necessarily means anything for what happens in the future...

brawlo

Unless you're running the longest TT you could find at the time and budget (63cm FWIW)

brian44

This is the situation in my case...my frame is at the top of the size range (albeit 57.5cm TT).

Now that it's been a little while, updated thoughts on the WX-R?

m@tty

unfortunately it’s still to have its debut on the track.
has been used extensively on the rollers and the Lemond Revolution feels stiff responsive much like it’s predecessor but fits better with a longer reach.
a crash in December and Covid in January has kept me away from the track .
