BaGearA Posted May 10, 2023 Share I rebuilt a 26 rim onto a hub that doesn't even have the anodizing on it with the same rusty spokes and it looks better than that *** I don't even true my own wheels , the above was just practice Kom 1 Link to comment Share on other sites More sharing options...

nick_the_wheelbuilder Posted May 10, 2023 Share Without having the wheel in my own truing stand it’s hard to comment and I hate being a keyboard warrior. It looks from the video like there’s one spoke that needs an adjustment and that would sort out that small hop, but yes, it’s not perfect. Just have it trued, would take any wheel builder 10 min or less. Something many people don’t realize is how easily a carbon rim can go out of true if a tight tyre is installed. I’ve seen spoke tensions drop over 20% once a tight tyre has been mounted, and the rim goes all wobbly, when previously it was arrow-straight. It’s more important that all spokes are at the appropriate tension and consistent, and not all over the map.

I’ve seen spoke tensions drop over 20% once a tight tyre has been mounted, and the rim goes all wobbly, when previously it was arrow-straight. The problem with these wheels is that the nipples are only adjustable from inside the rim, tape and tyre removed. Once the tire goes back on, it seems to develop this wobble, as if the rim itself is defective or too soft. I’m told the spoke tensions are all checked before the tire is refitted. I’d be curious to hear about experience with the p-slr giant wheels, i can’t imagine this is a spoke issue. Edited May 11, 2023 by Kom Link to comment Share on other sites More sharing options...

These are giant gavia pro tyres, actually bought these after I was told that continental gp5000 tyres i initially supplied were not compatible with the giant rim. In hindsight I should have pushed back, although the gp5000 do have a reputation for being super tight. I’m more convinced now that the rim supplied by dragon is defective. splat 1 Link to comment Share on other sites More sharing options...

Few even actually ride bikes themselves. The average bush mechanic (read non professional mechanic, but passionate cyclist 😁 ) is in my opinion, levels better in experience and equipment setup.

Two years later, and you seem to share my frustration as per the second post on this thread ..... I LOVE my Giant bike. But both "authorised dealers" in my area are seriously lacking "quality control" (to put it mildly) in their facilities. My bike now goes to a specialist bike mechanic for its major services. PS - seems the workshop in Somerset West is good. The logstics of two return trips for a bike service is just not practical .... Kom 1 Link to comment Share on other sites More sharing options...

I’m hoping Dragon will come around, but cutting losses and moving on might be prudent. Huge fan of giant product too, but no doubt that after-sales has gone for a ball.

Eddy Gordo Posted May 11, 2023 Share are there a couple of spokes that are not as tensioned as the rest? Link to comment Share on other sites More sharing options...

I’ve done a squeeze test on spoke pairs in both Drive and non drive sides, and they feel “relatively” even. I don’t have a calipre to measure accurately. if the nipples on these wheels were accessible this thread would not even exist, I’d just bush-mech it myself, but these particular rims are super finaky.

A friend has a new bike from another brand, different dealer workshops. 3 out of 4 services the bike goes back due to a lack of QC ... Buy the bike you like. Then have it serviced where you trust the staff 👍👍 Kom 1 Link to comment Share on other sites More sharing options...

Feel like its important to circle back that Dragon have taken back the rebuilt wheel and replaced it with a completely brand new wheel. Completely happy with the outcome - really important to say thanks to Gert and Gavin from Giant Cape Town to sort this out for me.
