Non-boost Hub - Kids Bike

Postby cep32 on Fri 17th Feb 3:09pm

So I have an old fork for a 26inch wheel available that I can reduce the travel down to 60mm on so I can put it on my sons 20 inch bike. The a2c measurement increases by only 20mm so I'm keen to give it a go. The only issue left to solve is that the front wheel is boost spacing (the bike is a Specialized Riprock with 2.8 tyres). I don't see why boost spacing would be needed on the front wheel especially given it is only 20 inches in diameter and he's pretty light.

The question is, can I rebuild his front wheel with a normal 100mm hub? Obviously there may be issues with spoke length and all that but other than than that is there any reason why I shouldn't?

Cheers,
Chris

assuming the 2.8 fits within the fork, i can see no reason whatsoever why you couldn't replace his boost hub with a regular width hub... you might indeed find you need to get all new spokes, unless the flange widths are within a mm or so of each other.

The bottleneck will be fitting the wheel and tyre past the brake caliper.

Yes. That's why they invented boost.
