Due to the slow season here at the shop I’ve been re-purposed and have been doing random construction and what-not so I haven’t had the privilege of photographing any interesting bicycles. I have however been relocated to one of our other busier stores and should be supplied with something for your viewing pleasure.
hey, im trying to convert an old 10 speed into a fixie but ive come into a block at the back wheel. do i need a new hub with only one sprocket or can i still use the old one?
if you want it to be a true fixed gear you will need a new hub that has threading for a fixed gear cog and lock ring. If you’re just looking to make a single speed out of it you have two options. A: leave the original 5 speed freewheel on and just set the chain on the preferred gear. this is the recommended method for proper chain alignment. B: take off the 5 speed freewheel and install a single speed freewheel. this method looks better but chances are your chain alignment will be way off and will probably lead to your chain skipping and popping off, this can be corrected by having your axle re-aligned and re-dishing your wheel, probably by a pro mechanic. Either method used you should look into a chain tensioner like the Surly Singleator…you can also use your old derailleur, although it wont look as nice. If you decide on buying a fixed gear wheel for your ride you will want to get a half link chain to get proper chain tension since you don’t have the adjustability of track fork ends a.k.a. horizontal dropouts. There are also some useful tips on the late Sheldon Brown’s page here. Hope this helps. Cheers!
oh dear bike shop mechanic, my hub doesn't have a locknut on the drive side and the rim is woefully bent.
I’m sure that if you stop at your local bike shop they will probably have a replacement lock nut available for you, and usually they are only a dollar or so. As far as your rim being ‘woefully’ bent, it’s hard to judge without seeing it but again the mechanics at your local bike shop can probably true it up (straighten) for you for around 20 dollars. In some cases though a rim can be bent beyond repair, if this is the case you have a couple of options… A. you can have your hub re-laced to a new rim or B. buy a new wheel. In many cases its simply more affordable to buy a new wheel (depending on the application).
Sorry for the lack of updates, I’ve had to wait the last few days for AT&T to disconnect and re-connect the service here in our building. I’ve got a couple of sweet bicycles to post up, but it’ll have to wait till tomorrow…until then…
