Rear wheel lacing

#1 PostAuthor: steve452 » Sun Jun 28, 2020 4:10 pm

Further to my previous post of today, herewith the rear wheel lacing. Any advice regarding errors in the pattern would be much appreciated. I started with the hub near enough centred in the rim, with the stampings side down, the valve hole at 12 o'clock and the hub shoe side up. I then inserted the first top inner into the hole on the right side of the valve and rotated the hub clockwise until it was again centred. Then I did the 2-4 process on the inners, and turned over and did the inners on the other side. I'm hoping that's the correct procedure. Interestingly, and something I hadn't noticed before is that the rear rim has two valve holes! Can anyone confirm whether this is normal?

Hi Steve
there are three "valve holes" in the rear rim. One is indeed a valve hole, the other two holes are ment to bolt the tire grippers in.
The two tire gripper holes are 180° opposite to eachother, the valve hole is near one of the tire gripper holes.
If it's a genuine "TAKASAGO" rim there should be 3 holes The writing on the rim should be Takasago 303 2,15x18 and the year and month of production. 3 A means: year of production: 1973 , the month of production: Januari .

Thanks for the advice Philippe. These are the original fitted rims (rear is dated November 1974 , see pic). I bought the bike on 1st May 1975. I can see the two gripper holes as they have a slight flattening which I'm guessing is the bed for a washer. I can't find a schematic anywhere showing the grippers so cannot work out what washers (plain/spring) go on the inside or outside of the rim. Do you have any idea of the set-up for this?

Central Wheels in Birmingham have said they do not balance wheels with "rim locks/security bolts" fitted, although they are quite happy to fit my "rim locks". I assume they are referring to the rear tyre grippers although I have queried this with them. Does anyone know of a reason why this is the case?

Hi Steve
the correct way to install a tyre gripper is first the protective rubber band, the tire gripper through the rubber band and the rim, a spring washer and a 8mm nut. You can always put a plain washer between the rim and the spring washer in order to protect the chrome but that's up to you.

Many thanks Philippe. You sir are a diamond. I'm guessing that what you mean by "protective rubber band" is what I call a rim tape.

Once again, many thanks and ride safe.
