    Fits a 2011 Trek 2.1 road bike

    I've been using crud road racer 2's for a couple of years but after my own clumsiness crossing toes with the front wheel standing at traffic lights I smashed the front, again. And then found the rear had also cracked in a couple of places as well. This isn't the first time this has happened so having looked around for alternatives I stopped in at the local trek dealer to ask their advice. They suggested some crud road racer 3's so bought some there and then. But the changes to the design mean it's now impossible to fit them to the front on this particular bike. The giant speed shields were the next candidate and to my great delight they fitted up no problem very little fuss. Having read previous reviews on here I threaded all the tiny grub screws into the fittings before installing the stay guides on to the mudguards. I'm currently running conti gp 4 seasons 23 front and 25 rear on mavic open pro rims and have yet to ride with the guards fitted but all looks well. Soon to be replacing the open pro's with dt Swiss r460's so it will be interesting to see if the extra width on the rims and the change to the tyre profile causes any issues.

    These are NOT Alloy/Aluminium

    I bought these specifically as they are listed as "unbreakable alloy". note - they are NOT. They are an extruded glass filled nylon type which is rigid and seemingly good but have not yet fitted to see.

    Not for Defy 1 Disc

    From the description of this product you would think that they would fit all all of the AluXX Defy models, however, they don't fit the Defy 1 Disc models. They look like a well designed and well made product but you need to check that you have the right model of bike to suit these mudguards. In better news, Tredz also supply the Crud Roadracer Mk3 mudguards and they definitely do fit on a Defy 1 Disc !

    Not suitable for Giant Rapid Hybrid

    Bought these mudguards on recommendation from Tredz that they would fit my Giant Rapid Hybrid with disc brakes. First issue was that there was no fitting instructions but I guess it's pretty logical how they work. Back mudguard went on great with a bit of fine-tuning of the stays. Front guard was a complete nightmare. The stay was far too short to reach from the quick release lever to the mudguard to hold it in place.The placement of the disc brakes made it quite awkward as well. Called Tredz up for more advice and Stephen was great -- called Giant for me and advised on either the SKS Problade or Flinger F35 as suitable replacements. Am waiting for these to be delivered before sending my Speedshields back. Great follow up service from the team at Tredz.

    Very poor

    Giant make great bikes but their mudguards for close clearance bikes are best avoided - and I say this after having been through 5 or 6 sets. The stays on these Speedshields are held in place by ludicrously small grub screws. I am a reasonably capable at mechanic with 40 years of experience but the tiny allen key needed began to spin in one of the screws, rendering the whole set useless. The bridges seem to be steel which solves the weakness the other kind have with breaking alloy bridges - but there is no point if you can't get them on and adjust them later on as needed. Avoid! The solution is a bike with bigger clearances as the constant fight against breaking, rubbing or rattling guards on close clearance bikes is a waste of time.

    Waste of money

    Do not buy these mud guards for your giant defy 1. They do not fit & are an incredibly flimsy build.

    Sturdy performer

    I took a chance and bought these to fit something other than what they were designed for, so this review may help you if you are in the same boat. I'd tried several different mudguards to fit a bike with limited clearance - Cruds, Topeak and SKS - generally of the clip on/off variety. All were a bit fragile and wouldn't last more than a winter season. These appeared to offer more rigidity with proper stays, a decent length and a chance that they would fit under limited brake bridge clearance with the cutaway design. They did - just - but I also had to flare out the metalwork around the bridges to get some tyre clearance even running 23mm tyres. My bike must also have shorter chainstays as I was unable to use the little rubber spacer behind the seat tube, but padded it out with some smaller rubber. So, yes they might well fit if you've not got a Defy/Avail if you are willing to experiment. You get a fairly rigid mudguard with decent coverage (yes, your brakes will get a bit mucky). The only issue I have is that the rear mudguard slips through the plastic bridge holding the stays over time and rough roads, which can lead to some tyre rub. This could be sorted with a little grub screw or maybe some tape.

    Fit 2014 defy0 large

    I didn't know wether these would fit my 2014 defy0 large frame. However in the end I got them to fit perfect I did have a bit of a rubbing issue around the brake area but this was easily fixed by slight bending the metal connecting pieces out. I'm running 25 tyres I wouldn't like to be using tires and wider but it does say ok for upto 28 width wether these would work I can't say. I've used these for around 150 miles and I am very impressed with how well they are keeping me clean and how quite they are compared to my friends mudguards. For some reason giant haven't made use of the fixing thread on the frame which is a shame as I feel this would be better then the rubber strap supplied that's why they get 4.5 stars on build quality

    giant mudguards

    Well made and appear sturdy. Fiddly to put on bike and little clearance. Will see the outcome tomorrow when I'm out and about.
