    Strut brace won’t change anything as it’s not body flex causing the wheel to rub on the strut and its not flexing in the strut. It will be wheel flexing or play in the wheel bearings. The stub axle and strut are as one and very solid so will not flex relatively to each other. Check wheel bearing play and or add a spacer.

  2. Big XC race weekend coming up in Canberra at Stromlo presented by CORC, two weeks before Nat Champs. 29 and 30 January. Saturday is Junior World Series (JWS) inc UCI C2 XCO and Sunday is a National T1 race. 
    Should be a great weekend of racing. Saturday will also be round 1 of AusCycling UCI XCO series. 
    Beers at the Handelbar after racing.

  3. Donation to this web site and it’s yours.

    Having a bit of a clean up and rediscovered the towbar that was attached to the rear of my 240 when purchased. Never going back on my car! If anyone wants it it’s yours. Pickup only from Canberra. If no one wants it the steel will be repurposed. I’ll put it under the house in the short term. 
    Yes I painted the shed floor.

  4. It’s a great time of life when the kids start purchasing their own bikes. You still get the thrills but without the expense. Daughters new bike arrived today. It was delivered to our house so I could build it for her. 
    Only down side is that she is going to be so fast on this dam thing. 
    Classic how you can get a box from Germany in a week but cannot get click and collect from Bunnings in that time.

    Gotta love that unsprung weight :)

    Actually very little weight gain over standard breaks. Each MK63 (copy) calliper is less than 100g heavier than standard calliper. The discs are comparable. Yes there are lighter overall options but you would probably only notice the difference at high speed on a race track. These fit easily under 15” wheels and I think there  is a historic appeal to this setup.

  6. Lockdown has provided the opportunity to get a few maintenance checks done. I wanted to check the front hubs and wheel bearings. So while doing this I took the opportunity to swap the front brakes out for the copy MK63 callipers and disks that I have had sitting around for some time now. Awaiting brake lines to finish the swap off.

  7. If you look at the parts manual it may help you gather some of the information you seek. It may take time to decipher but it may be an interesting journey.

    If you donate to the site you can get access to a digital copy of the manual in the donating members area.

  8. Haha @Linton I think you are correct but  I don’t think drilling holes in the hub or welding wheels would be seen as legal either. There is not much correct or legal about this conversation so far! At the end of the day making any changes to standard would need to be engineered to keep it “road worthy”. I believe using something like this could be engineered but I don’t think drilling holes in the flange would be.
    I know what I would be doing. Either leave as is with 4 studs or getting 5 stud flanges.

  9. Do you have wheels or do you still need to get them? You may be better using an off the shelf conversion spaces kit and running an offset wheel that takes the spacer into account (If you search the forum you will find answers about wheel offsets and what a standard wheel offset is).

    Using something like this will have two advantages. It will work and maintain the integrity of the hub and it can be reversed if you want to go back to 4 stud.

  10. New trails just to the west of Canberra officially opened a few weeks. Cotter Pines is a collaborative effort by the Kowalski Brothers team and local trail builders Iconic Trails. ACT gov provided some grants to assist with the works. It’s a mix of old school hand and machine built trails. Well worth a visit if your in town. Another place to ride. We are well spoilt.
