Giant SpeedShield Defy / Avail Aluxx Fender
Fitted my
Giant Speedshield Defy Fenders last night. For a 2015 product designed with the close tolerances of the Defy/Avail in mind over the previous
Defy Fenders I was quite disappointed.
The fittings between the brake bridges are the same as the old fenders, there are very few options Giant have due to the tight tolerances here. Personally I found the 'curve' of these bridges too tight for my 25mm tyres (Continental 4 Seasons), now my tyres might be quite wide on my Campag Khamsin G3's compared to the 23mm Giant tyres on their PR-2 wheelset, but these guards are listed as compatible with up to 28mm tyres. I would take that with a very large pinch of salt - if my slightly wide 25mm were enough to snag the bridges then there's no way a narrow 28mm is going to fit! I bent mine to larger clearance with some long noses.
The material these guards are made of is a matt black finish plastic, due to their changed shape and change of material over the original Defy guards they do feel more sturdy. There is certainly less flex and 'bounce' which can only be a good thing. They're flexible enough for purpose, yet rigid enough to decrease 'banging' and clattering which you got from the old guards bouncing around (more on this later).
The guard rails are very sturdy and strong, on par with the old, mounting is very similar to frame mount points. No safety/quick release like SKS/Cruds (should something get stuck in the guard). The bridge fittings they slide into (which you slide onto the guards) are plastic, they grip well and having the option to slide them to different parts of the guard is nice (like on my SKS Raceblade Longs, just tighter fitting) and allows you to place them in the optimum position for your setup (not an option on the old Giant guards). A word to the wise - the guard rails are held into these plastic bridges by tiny grub screws, there is no guide/tap in the holes so it is very easy to screw them in at an angle/strip the plastic as you have to screw them in quite a way to get enough of a hold on the rails. These should've been made of tougher plastic or had some other fitting.
At the bottom point of the rear guard is a rubber 'sponge/spring' thing with a adjustment strap to hold the base of the rear guard to your BB area via the seattube. A much better design than the old (which was held on with a screw)
BUT on my Defy 1 2015 I found it fowled the chainring derailleur cable as it is right at the base of the seat-tube. My Defy is a fairly normal/mid size so it's not my frame being too small for these and I'm fairly sure all of the Defy range use the central base of the BB as a guide for this cable (fairly common on all modern bikes with STI's). I worked around this by cutting the middle section out of this rubber stay so the cable fits through (this way I can still strap the base of the guard to the BB area).
Final conclusions and thoughts after riding with the guards this morning... The 'banging' noises compared to the previous guards are definitely decreased, they are still there to a degree (I'll be moving the guard bridges around to try and combat these) but they are more of a banging than a 'clattering' like the previous. The noises are very similar to my SKS Raceblade Longs which I know are from the guards hitting/rubbing the tyres rather than the flex of the guards banging the frame (like the previous Giant Fenders did). These guards work, I've not ridden with them in torrential rain yet but after finding a few puddles this morning I know the coverage is similar to the previous and Raceblades. More longer term I may go back to the Raceblade Longs as they are removeable without having to unmount my brake calipers, although I like the matt black look of these Speedshields (compared to the black gloss shiny original Giants and Raceblades).
