It seems this is the case! 5/32, 30mm inner diameter and 37mm outside diameter. In total 16 ball bearings.

Hello , does anyone knows the dimensions of caged bearings for a 1' threaded headset?

I am doing a complete restoration on a 70s bike.

I would like to order good quality bearings from SKF, so I need to know the size specs.

Many thanks in advance

Hello, what size cartridge ball bearings shall I buy for my Formula flip flop hubs?
Any better quality recommendations?
Many thanks!

Hello, I upgrade an old Koga Miyata bike 1977 model. I need to get a wider handlebar for more comfort, I measure the diameter of the bar to 24.8 mm. Is this an old standard? The handlebar brand is BF - France and the stem brand is SR.

Would I be able to fir a standard 25.4mm handlebar in this stem?

Hi,
I am working on an old Koga Miyata bike for the late 70s.
I need to replace the handlebar since it is very narrow. The bar is similar to the one in the picture. I measure the bar diameter at 24.5-24.6mm, is it possible? The standard classic Nitto bars I can find are 25.4mm, would it fit?
Thanks

thanks!!!! at this price I will get a new crankset for my old Dutch bike! I may buy the Sturmey Archer which is even cheaper!

I am converting and old Dutch bike to fixed. I build new rear wheel and i need to change the old Shimano Nexus Chainring.
I only managed to find a picture in the following link, I have never seen something similar before?

My question, is there a separate Nexus chainring or is fixed in the crank?
where can I buy a Nexus chainring, if so...?

Could it be that the frame is wider in the bottom bracket area so the BB cups sit further out on the axle?

This is a mistery!!! I just found the email with the order. It is clear, SKF JIS 107! Should be fine. It does notbmake sense, now I will have to take out the bottom bracket out and check the label...?

This I understood, though, will 1.5mm create much more friction? would it be noticeable?

Shall I buy a new bottom bracket 107 mm or it is better to get a 110mm one? I think to buy a Shimano UN55 BB 110mm. Would a 110mm BB change much the chain line?

My Miche Primato Advanced crankset has bottomed out on the bottom bracket. I have a Dolan Seta track frame with SKF JIS 107 bottom bracket, as per (JIS) recommendation of the manufacturer. It also makes a creaking noise on every pedal stroke.

I want to say that when tighten the bottom bracket bolts the crank arms go so deap on the bottom bracket axle that they get in contact with the bottom bracket cups.

Anyone experience something similar? Shall I go for an 110mm bottom bracket?
I was also thinking to go for a Shimano BB-UN55?

It may also worth the cost to buy ceramic bearings since they are smoother and last longer

Can I remove the rear dropout spacers from and old steel frame with horizontal dropouts?
They look like this but cheaper:

I need to pull the wheel axle to the back end of the rear dropouts to gain some space for bigger volume tyres.
Do we really need these spacers?

35 plus mudguards looks a good option!!!
I assume that at the rear with one link longer chain you may utilize the above setup. On the fork though isn't it very tight?

What is the tyre clearance on the Pompino? it looks that 700*32 is possible, anyone tried 700*35 or 700*38?

Hello, I am planning to commute form Maida Vale, W9 to Canary Wharf on my fixie Dolan Seta this afternoon ! Anyone cycled through Hyde Park, Green Park, Cycling Highway along Thames river, along DLR cycling path?

Yes it is both single speed. Would you be able to say which tool is the best for all around freewheel removal. If I had one tool would it be the Sturmey-Archer or the Shimano one?
Thanks!

Does Sturmey-Archer single speed freewheel has the same removal tool with Shimano freewheel?

I can put mudguards in both, though FXE will be easier with proper SKS. For Seta I can use Crud Road race or SKS raceblades.

Yeah, bling it is, the Seta would pep up my commute and bring this art element in my living room.
I just wanted to enjoy it for a few years and get a bit more comfort that an alu frame to make it worth.

I need a new frame for my hand build OpenPro/Sapin/Token wheels and full carbon peripherals. I ride everyday 30 miles to work and longer 50-60 miles on weekends with every weather condition. At work the bike is parked in a secure garage and at home in the corner of my living room next to my sofa!!
Shall I go for the Dolan FXE alu frame or raise the standards to Dolan Seta carbon frame. My concerns are two, reliability and comfort.
Reliability: Will the Seta carbon frame cope with the everyday race to work and the bad weather elements or the FXE will be more durable?
Comfort: Will the Seta be more comfortable that the FXE in absorbing road buzz?

Here are some pictures:

I can see pictures with the seatstay bridge is about 1cm from tyre with the rear wheel axle relevantly forward in the dropouts. If the rear wheel axle is moved backwards (chain cut with one link longer) then it should give more space for bigger tyres, check pictures link below:

Dolan website states tyres 23mm Max, though it looks that would take 25mm...?
