I’ve emailed the seller about a refund. Wouldn’t have bought this had I known it required a lockring and spider change, was told just need a bsa30 bb.
Or I could buy a plastic frame
@EndpointBraden thanks for the offer on checking parts. I’ll let you know tomorrow if I can’t get a refund
It’s not the spacing that’s the issue.
The bbright specific locking is the thickness of the standard lock ring and the drive side rotor spacer for BB/PF30 for their 30mm spindle cranks. Swapping them exposes enough spindle for use with the BSA cups.
The issue is that the bbright spider is shaped to sortof envelope the lockring to give a smoother looking transition to a BBRIGHT frame. Rotor is telling him the BSA30 cup can’t fit inside the bore of the spider because the cup is too large in diameter (not thickness).
I remember monkeying around with some bbright spiders a few years ago and thought the cup did fit inside the spider though.
Yeah that’s what I figured is happening here as well. The lockring that’s present appears to be same diameter as the bsa30 cup. If I remove it there is still the issue that there may not be enough spindle.
Even if this is ground down (as would be the case with a standard lockring) I don’t think there’s enough lateral space for the spindle. This spider looks quite wide.
There’s discussion about this here but the narrow spider photo doesn’t load: https://forum.slowtwitch.com/forum/Slowtwitch_Forums_C1/Triathlon_Forum_F1/Rotor_3D+_crankset_doesnt_fit.__Why_P5139192/
I found this photo
The BBRIGHT lockring itself is more than 11mm thick. The part of the BBRIGHT spider that sits between the crankarm and lockring is the same thickness as the normal spider. This is how one can remove the BBRIGHT spider and run something like an SRM or Power2Max power meter in place of the spider. The BBRIGHT lockring just act to integrate the standard lockring with the BB/PF30 spacer that is used on the drive side of ALL 30mm spindle frames EXCEPT BB386.
Once you get the lockring off it will all make sense.
Gotcha, thanks for that. It sounds like Rotor is saying this all won’t work because the BSA30 cups are bigger in diameter than the lockring, hence that spider doesn’t have enough, I’m going to call it, ID, for the BSA cup to fit…
Got my refund so back to my Shimano crank that seems fine I guess
Why is the Dunlop valve still in use, especially on euro trekking bikes?
Any insight to its history? Sheldon has very little other than calling it a Woods valve, which is a new name to me.
Did Chrome stop making SPD bike shoes? everything is flat pedal now, and the only pair of SPD shoes is on sale.
Sub-question, what’s a good pair of bike shoes that don’t look like soccer cleats that I could wear out to a nice restaurant or whatever?
Is this the thread for dumb questions? Well, I have a set of Mavic Ellipses that were included with my track bike. They look pretty sharp. Other than the wacky lockring is there something I should be aware of?
they suck
Is it a track only bike? you might be fine. I’ve seen a ton of problems on sweet fixxxies though. lots of axle and bearing issues, but maybe related to weather and poot maintenance… i’ve definitely taken a dremel to at lease a few different sets. mostly problems on the rear hub.
aw do they? booooo!
yeah, it’s going to be ridden at the track only. from what you said it seems like I might be alright as I’m not going to be riding in the rain and throwing down sickkkk skids anytime soon. really not surprised to know that there are problems with the rear hub cos I’ve had issues with some of their other wheels.
if I wanted to go in the hand built direction what kinda hubs would you all recommend?
get adam hansen to make you something
but more seriously Quoc Pham
i would treat them the same as a pair of aksiums on a one bong road bike. they will probably last for a while and work fine, but they will eventually fail in a way that is harder to fix than just buying a new wheels.
Fooker + whatever shoe you’re wearing
Giro Republic look pretty good and are not at all stiff.
5.10 District have come the closest to looking normal, while actually being walkable and still really usable as clipless (no crazy DZR failures)
the Quoc Pham SPDs I’ve seen looked like odd platform shoes IRL
doesnt work for tandem + hundreds of feet of climbing, unfortunately.
Oh I have only been paying attention to the road ones holy shit the city model “Weekender” looks like those horrid chunky dress sneakers from the start of the mileenium.
I stomped into my first internship in a pair of Steve Madden nonsense shoes that were disturbingly similar to those
