I didn't realise it was a BPM. Have a look on the axle on the disc side behind the inner nut. I've seen them with a full-size washer on the bearing so that it's tightened against the inside and outside races, You need a narrow washer that can only touch the inside race.

 

On the freewheel side, a normal washer will rub on the freewheel. Again, you need a narrow washer. A standard washer is 24mm O/D and 12mm I/D. You need one with 20 mm O/D.

thank you d8veh for pointing that out.

Anthony, there are two narrow washers, one for each side, if you place them at innermost, they should keep the other washers away from the bearings.

Just to make it clear, the 20 x 12 washer is only for the freewheel side. On the other side it needs to be narrower - something like 18 (or less) x 12.

I don't think the rotor side will be an issue. That'll just be a spacing issue to get the caliper lined up I think. At the moment the rotor side is just the ar washer up against the internal nut.

can you still spin the wheel (in the forward direction) easily before tightening the wheel nuts?

Just tried a quick dirty fix using brass compression fitting in place of washers to bring the ar washer out far enough and now it spins 8-10 times when spun by hand so just have been a rubbing washer .

The washer I'm talking about is between that nut and the bearing.

I never checked under that nut, I'll pop it off later and check

Well all is good with the new washers, spins about 10 times with a moderate hand push.

 

Next problem to solve is handlebar config now. My Shimano shifter and hydraulic brakes pair together well but twist throttle interferes with shifter and thumb throttle has to be positioned too far away. Any recommendations for a change in shift or brake?

Yes, these Shimano integrated ones are perfect. Plenty of room for a throttle:

 

What model are they?

I have a integrated hdb set very similar to them but all in black on my Boardman 700c.

Mine are Shimano M600 Hone they came without callipers other wise all the bits and bobs with mineral oil were in the box for about £60 on ebay.

Seems they're discontinued, found the those

 

Shimano Alivio M4050

 

Looks similar

I found these earlier. 9 speed though.

d8veh's pic shows the m765 XT's. There's a used pair of them on ebay at the mo in Greece, they are a buy it now sale for £40 delivered. They are for 3 x 9 spd cassette but if you have only 8 spd you should be able to get them to work ok using the stop screws.

Damn, this conversion is getting expensive.

I fitted a 9 speed freewheel to keep the same as my cassette. I'll check them out

why do you want to change your levers?

if it's just to fit the brake sensors, it would be much cheaper to make your own sensors.

Not worried about the sensors, it's fitting everything on the bars. Consolidating levers and shift seems like a good idea in the future.

Well, caliper post arrived. All together now, running thumb throttle in an awkward position until I get new shifter/brake combo. Test ride in the morning.

 

Are the anti rotation washers adequate or should I think about torque arms?

I always fit at least one torque arm on the brake side. I anchor it to the rear caliper adaptor screw.

 

It'll be sunny tomorrow. Hooray!

Yeah, think I'll order one. I'll go for a gentle ride tomorrow. Take my camera out and see if I can snap some beavers that are on the local river. I don't fancy my chances.
