All The Six Fifty Bees Thread! (650b, 27.5 etc.).

I haven't got any actual 29er frames.

Ah, 135 would work, curious to see if there's clearance in the 1x1 without running the wheel all the way back

Dirt wizards on 50mm rims are 76.5 at their widest, about 345 from the axle.

Bottom gear on a 10s cassette on a 135m axle should be about 25mm off centre.

Add 6mm clearance and 3mm for half a chain width, the chain needs to be 47mm off centre at the tyre, so 51mm chainline and a shorter chainstay will give you better tyre clearance.

As the rear mech pulleys move in the same plane as the sprockets, the shorter your chain is the worst tyre clearance will get.

@edscoble You been anywhere near a Datum?

Any estimates on the cheapest rim brake 650b road wheelset?

I'm planning a 650b conversion and stumbling over the first hurdle.

I dunno about built up, but something based around these:

Should end up cheap.

Think this belongs here:

I remember that, loved it, look stupidly fun.

All that money and then those cheap-looking chainrings?

that English is pure money over sense

Those crankset are the lightest you can get.

I know about the Claviculas, it's just those rings are horrid

Silver TA would look better.

fwcking expensive and light crankset... brooks saddle. what the actual feck?

Panaracer Gravel King on Hope Pro4/Stans Crest wheelset. Tyre weighs 350g at 40mm, hoping the tyre stretches a bit. Will try them on my GT Grade tomorow but they are for a yet to be build road bike.

Super awesome!

Rear tyre? Not so easy. Friendly lbs to the rescue! Great to have a lbs open on Sunday.

Only just fits the Grade. Will ride them a bit until the other bike is done.

If the rear was harder, it mean the tyres bead wasn't in the middle of the rim making it a lots harder to install.

Nice work, @Chak would be happy to know there's another option.

Definitely a better option than the Cannondale Slate now.

I guess, tried different things for two hours. Pinched the beads together, soaped up the sides, try and "help" the beads on the rim. After a lot of swearing and pumping like a mad man I called a bike shop and asked if they had an air compressor. Showed up, one squirt of air and the beads popped. Squirted in the Stans latex through the stem, another blast of air and I walked out of there shaking the wheel while I walked back to my car.

edit; didn't realised you're using tubeless, best to get either a pump like the Topeak Joe Blow Booster, or use Co2 cannister to inflate tyres, need a proper boost of air to get tubeless to work generally.

Short update after a ride around the block on the Grade: big tyres make a lot of noise, Hope hubs make a lot op noise, 3 bar rear 2.5 bar front is too much gonna try 2.5/2.0 next, cycling after an hour of one-on-one kickbox training is hard.
Oh, and after a day the tyres measure 42mm with calipers.

Always got bad results with co2 canisters. Low temperature congeals the liquid pretty rapid and doesn't flow around the rim well. We managed to wrangle one of these and it's yet to fail.
Decided I'm going to build the wheelset anyway, then just try them out on different frames as they come along.
