Frame will be steel?
If so definitely a Kelly Bike Co style EBB.

have opened a whole can of worms when it comes to chain tensioning

Let me add to your confusion by suggesting that you can't beat track ends with chain tugs for a truly bomb proof solution.

Yeah, steel frame. Interesting, will have a look at that. Looks need but won’t dirt and stuff get up in the BB shell?

@Thrasher Good to know - thanks!

@gbj_tester Sounds like the kind of simplicity I’m after!

my rockers didn't slip but they had to be torqued up a fair bit. In my mind rockers had the advantage of being future proof in that if a new dominant wheel standard occurs then paragon will likely make rockers for that standard that you could swap in at a later date. Same goes for disc brake standards.

My Google-Fu must be weak today because I can’t find any real world examples of this. Would be great to see a photograph of this set up.

A good point. I guess with rockers I could always change the plate if I want to run gears in the future? But then I’m limited to 135 rear hubs...

The possibilities are almost endless and I haven’t even asked about bar-end shifters vs. grip shift style shifters yet, haha!

assuming it's an mtb you'll have discs so horizontal track ends, plus discs is a bit of a no go.

Don't Rolhoff have their own dropouts anyhow if you're going that way?

This looks ok i guess

and this!

I'd say be wary of over complicating things

out of all those monstrocities I think rockers look best

horizontal track ends, plus discs is a bit of a no go

Depends, caliper inside the triangle means you have to move the brake every time you move the wheel, but my Azonic has the centre of the caliper directly above the axle. The axle slides along a tangent to a line joining the caliper to the mid point of the slot, so both the radial and angular displacement are negligible. I do have the problem that I have to remove the caliper to get the wheel out, but that's unique to the long 4-pot M755 calipers and wouldn't be an issue with a 2-pot.

Paragon announced these last year and they're a bit cleaner looking than some of the other rocker/poly-drops out there

They're nor really horizontal dropouts though as they angle upwards. I think the intention is that the wheel will be moving backwards due to use of a larger tyre rather than purely for adjusting chain tension.

The bottom one looks like a Tatjana van Vark...

Presumably you'll also be using a larger tyre up front, so the angle does nothing useful. If you wanted to keep BB height constant, it would need to be angled at about 45°, and you'd need an adjustable length fork too 😀

I think I need to look at some track bikes now, just to clean my eyes.

Wait Kelly is back in business? Awesome!

Found this fella in a pile of free exercise equipment in my parents town. 600 and DA cranks!

Have a go at achieving chain tension with rockers and see how you find it. Personally I find it really difficult and annoying. I'd favour the paragon breezer style sliders with built-in tensioners (I've not used them but they look better). Either way if you go paragon, replace the standard bolts with cap head versions that are driven by a 6mm Allen key or a torx, as the ones paragon supply as standard, dome headed and driven by a 5mm allen, can round out within the recommended torque range (so says my experience and also according to paragons documentation).

I didn't know it was out!

They don't make it harder than it should be

Nice! but why did you get rid of the DA cranks?

Help! Chainstay cracked on my beloved Standert so need a (hopefully temporary) replacement ASAP.

Looking for a 56cm/large racy road frameset. Disc or rim, I have parts for both. Budget up to around £500.

Stack and reach around 575 and 390 on the Standert.

About a dozen years ago he closed up shop.

In the late 90s early 2000s Kellys were some of the few non-New England custom bikes you’d see at cx races in New England. I’ve had a fork and stem of his on a bike way back when, was saving up for a frame in 2003 but had to float my gf two months rent instead :(

Nice! but why did you get rid of the DA cranks?

Needed shorter cranks for the 650b conversion, a 48 big ring is also a bit more user friendly around here then the 53 that was on there.

Don’t worry I have use for the DA cranks.

New project day!

The build will be for my partner, gonna include wide tyres and 1x gearing, keeping the original 7s derallieur

Might want to pick up one of them NW chainrings in that case. Unless you have one there already, can’t see on phone.

Excuse the old Iphone shitty pic 😅

Been looking for a NW 94 bcd 5 bilt for the STX cranks, but seems like there’s very little market, and the only ones i could find (stridsland) are out of stock, so I guess a regular one will have to do for now.
Anyway it’s most likely to ride on tarmac and paths only, hope that isn’t much of an issue.

Can you find any from Wolftooth where you are?
