Front wheel conversion

navrig2

I have a Shand Stoater which I used for a long tour some of which involved offroad gravel tracks. I used the original wheels -Hope 20Five Pro4 700c. The front came with a 12mm diam thru axle and a hub dynamo.

Now I am back from the tour I am going to use the bike as a gravel bike. I have taken my Race Face Aeffect 650b wheels from my MTB and fitted them to the Shand. The rear slotted straight in and I fitted 48mm MTB/gravel tyres.

I want the option of swapping out wheels without the hassle of changing tyres. So gravel ride one day and tour the next day.

However the front is not directly compatible. The MTB front wheel runs a 15mm axle with "end caps" sized for 15mm, The Shand end cups are for the 12mm axled dynamo. This means the wheel doesn't sit into the end of fork cups to allow an axle to fit thru.

Is there a conversion kit which would allow the wheel to sit further into the cups so I could slide in a 15mm - 12mm convertor.

Or am I consigned to buying a different wheel? When I look most fronts come with 15mm axles.

After a lot of searching and a chat with Shand I realise I cannot convert the 650b to sit in the front dropouts.

I am now looking for an off the shelf 100 x 12mm 650b front wheel.

Any suggestions?

Why not just make your own adapter. Should be able to source a 15mm outside diameter metal tube with 1.5mm thick walls and cut it to 100mm length.

Something like this:

Or do you mean your current wheel axle is 110mm OLD wide but the gravel forks are only 100mm OLD?

The drop out diameter is too small for the 15mm axle

You would cut the 15mm pipe to the same length as the hub. You would still have the 12 in the drop outs as usual.

No, the end of the fork will have a 'cup' for the end caps of the hub to fit in which supports the wheel while you put the axle in. On a 12mm fork, these may be too small for 15mm end caps, which sounds like the case here.
