Bmx Hubs

[Connor]

I was thinking i went on a bmx and it had emense engagemeant unless its something to do with chain length, but like a profile hub could you but it on a stock trials bike. (Y)

thanks

BMX rear hubs are 110mm in width and mtb hubs are 135mm in width so unless a company makes a stock frame with 110mm spacing then you cant. Also if I remember rightly the new 24 curtis trials bike has the option of running a bmx hub in it if you ask for it.

you can get a 135mm profile, but at the minute im running a dmr revolver with an acs, and thats a great combintion

A BMX has a lot higher gearing, which gives you more positions for your cranks when having a rear freewheel.

The profile has 48 ep's . For example ,on a 20" trials bike you have 18:12 gearing.

Equals 3:2, or if you like it 150% of 1:1 gearing.

48*1.5=72. So, on a mod with 18:12 gearing and a profile you get 72 positions.

I dont know much of BMX's, but lets say someone's running 36:12.

That would make twice as many positions as on a mod trials bike = 144.

(and twice as high gearing)

Hope i managed to explain that... (Y)

do you think a bmx hub with an eno would be much strong, and can the hubs be laced to 36 hole wheels. I'm having a custom frame made and i'm wondering if its worth the trouble?

[ScotchDave]

Bad idea, this will slow down engagement. Also most bmx hubs are now made in 36 and therefore surprisingly can be laced to 36 hole wheels. B)
