I am inclined to agree that the problem is due to the fairly thin aluminium piece left behind after the reflector cut-out and tread cutout. I'd prefer the reflector to be mounted externally, keeping the pedal in one piece is more important to me than keeping the reflectors. I usually accept they are only temporary companions anyway, much like the ones on wheels.Dr C.https://www.blogger.com/profile/10234078254243840589noreply@blogger.comtag:blogger.com,1999:blog-8919432872771641105.post-80299684914931332632011-03-07T14:37:46.665+00:002011-03-07T14:37:46.665+00:00This looks to me like a fatigue failure, where the...This looks to me like a fatigue failure, where the initial crack began at the fairly sharp corner of the reflector cutout. I believe Brompton switched to this design of pedal because the externally-mounted reflectors were prone to break! It could be alleviated by using a larger radius on the corner of the cutout, or more simply by moving the outermost 'tread' cutout a few mm outwards (to the right in your photo). Notice how the innermost cutout is a bit further away from the corresponding corner, giving a thicker section. The pedal didn't fail here!<br /><br />This would make the tread cutouts noticeably unevenly spaced. I suspect this is probably the real reason why the design ended up this way! Alternatively, going back to something like the previous design, but with a metal rather than plastic retainer for the reflector, might be preferable.<br /><br />I would also expect this problem to be less likely to occur to people like me, with wide feet. Did you happen to notice the shoe size of the previous owner?<br /><br />MaxAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8919432872771641105.post-37212048434153454992011-03-01T12:08:25.978+00:002011-03-01T12:08:25.978+00:00I've been having bike issues recently as well....I've been having bike issues recently as well. My gears have been slipping as you know, then I threw 7, yes 7 spokes on my rear tyre a few weeks ago. Then I had a flat tyre on Saturday too. I replaced the tyre on Sunday and have now had the gears (hopefully) fixed. So should be up for my first ride with the Stockport Community Cycle Club on Sunday. <br /><br />It's a road ride to Knutsford and back so should be good fun. They ride at a casual pace so should be good leisurely fun.<br /><br />I should hopefully be test riding a MTB on Wednesday night, so the Manchester/Liverpool ride will probably be it's first major outing.muldydoonahttps://www.blogger.com/profile/14683624558130148974noreply@blogger.comtag:blogger.com,1999:blog-8919432872771641105.post-31382839365411951262011-03-01T10:55:11.625+00:002011-03-01T10:55:11.625+00:00My folding LH pedal is quite battered and scrapped...My folding LH pedal is quite battered and scrapped from hitting it off the ground whilst pedalling around lefthand bends occasionally (and its second hand). That seems chunky enough to take the abuse though. I also had to replace the plastic RH pedal, when the bearings ground to dust over one winter. <br /><br />I wasn't keen on the look of the ally RH pedal, even less so now I've seen yours!.Jimhttps://www.blogger.com/profile/13570415802364596822noreply@blogger.com
