    Can't comment on the radars, but it normally only takes a few rides to get the spongyness out of the brakes. Any residue on discs or pads should hopefully disappear quickly unless oil based in which case it will ruin the pads. Make sure you ran the bike back for its post purchase check and get them to bleed the brake if they still feel iffy. Some movement will be detected under braking, watch how your forks flex when braking, I tend to use brakes as a last resort as with experience you will get use to carrying speed I to bends etc, rather than hammering them to stop me dead. Never fully expect a website to be 100% truthful, they can and will alter specs. The bike you have is a good starter bike so just ride and enjoy it.
    Too many bikes according to Mrs O.

    Website says Tektro Auriga Comp brakes, not Hayes? Advise you speak direct to the shop if you have evidence that it was advertised differently.

    Pads will take a short while to bed in but you can speed it up by hitting a decent hill at speed and applying the brakes firmly (and controlled) to bring you to a solid stop. Then get back up the hill and do it again, and again. Personally I repeat circa 10 times. The brakes at this level aren't going to offer huge stopping power or modulation so the spongy feel may remain OR they may benefit from a bleed. Take it back to the shop with all your queries if I were you.

    Ahh, I see now. The tektros are on the 26" 540 whereas the Hayes are specced on the 27.5" 540.

    So does any one know why the ones from decathlon have not got the crosshair adjustment on them and why the levers are different

    Do they look like the levers shown in the Decathlon product page image, or the ones shown on the Hayes Radar page (https://www.hayesdiscbrake.com/products/brakes/radar/) - clearly there are two different versions out there it seems.

    They are defo not like the ones on the Hayes radar website, are there two types of the Hayes radar then and how go on when need new pads and bleed kit?

    I think it would be helpful if you posted pics of the levels and calipers that you do have so we can see what you are comparing with.

    Perhaps Hayes do an OEM lever and caliper, sell it only to manufacturers etc.

    This picture (from the 540 product page) doesn't show the grub screw adjustments on the caliper which I am presuming is the "crosshair" adjustment feature. http://www.decathlon.co.uk/media/835/83 ... 93882a.jpg

    So it looks like there are two versions of the Hayes Radar calipers. One with crosshair adjs, and one without.

    This is also backed up by looking on the Hayes website for the installation manual which you can see https://www.hayesdiscbrake.com/wp-conte ... all_EN.pdf

    On this there are two caliper installation sections - one described as "Mounting Caliper (Crosshair equipped calipers)" and the other as "Mounting the Caliper (For calipers without Crosshair)"

    Hope this helps!

    Thank you i think your right there is two types, so as for bleed kit and pads they will be the same as the normal radars only diff been the crosshair part

    Yep.

    Its not unusual to come across parts on OEM bikes that are different from the nominally the same after market part, but in this case it seems Hayes genuinely market two different versions.

    I have Formula R1S brakes, they are a mix of an R1 lever and an RX calliper and only available as OEM fit, Lapierre used them a lot.
