dont mean to jack your thread or anything, but i dont have horizontal drop outs on my frame....i cant run fixed?
-
@peahead: you can run fixed with horizonatal but not track dropouts. you won't be able to or need to run chaintugs tho. the only difference is that you'll have 126/130 mm rear spacing, compared to bikes built with track dropouts which are 120mm. If you've got a steel frame you can cold press the rear, or if not you can space out the hub.
@Danewesley:If you have vert dropouts you'll need to either use a magic gear (not easy), get an eccentric BB or hub (not cheap) or if you have a steel frame get the dropouts changed. Ted at FGL will do it for something like £50 or so.
For all conversions you need to watch your BB height, track running fixed generally required a higher BB as you can't control pedal strike going around corners as easily. there's a thread somewhere.

@peahead and @Danewesley: listen to fred

yeah i knew i could run fixed. I only went in to get them the check the bb thread size!!! They all started talking down at me when i mentioned "fixed" !!!
-
I ride a converzion* that has short but almost horizontal dropouts, yep, it's a road frame so has the slightly lower BB. Never, ever had pedal strike problems (use MTB style clipless pedals, and that may be the difference).
BTW, also use a DIY chain tug on front facing dropout, driveside. Totally reliable.

Thanks for the replies. I actually felt like a bit of a goon when they told me i couldn't go fixed unless i had the rear dropouts changed to track dropouts, and then told that "you'll have to bring it in mate so we can sort it out for you"!!!! I tried to gently suggest that the horizontal dropouts were more than ample to get good chain tension, but then told i would "forever be tighening the bolts up cos you cant have chain tensioners"
-
Bridgwater. I'm not hating the guy, because everything else he told me about carlton was very interesting. It's actually a good shop. On BB heightt, if it's low, theres not a lot you can do is there?
-
Beware of confusion between chain tensioners and chain tugs. Tensioners are just for single speed and mean you can run SS with vertical dropouts. Chain tugs are what keep your axle from slipping forward, particularly on cromed or unpainted frames. Tugs are for maintaining chain tension on a fixed-wheel setup. Different combinations of track nuts and droputs have varying degrees of 'bite', those with little bite will need chain tugs. You may also need chain tugs if you like putting the power down from a standstill.
-
I'd feel bad naming them, but it was interesting to see the looks i got when i mentioned fixed. I'd liken it to the looks you'd get saying the C word in church.
Sorry Chris I did confuse the two but did mean chaintugs!!
Shorter cranks for sure, and narrow pedals I guess.

If you've got a steel frame you can cold press the rear, or if not you can space out the hub. []
I presume you meant vertical dropouts and not trackends, since of course you can run fixed with trackends!!!

Luckily, the BB thread was in good nick, and also wasn't raleighs own thread.
The BB shell measures 71mm though on a vernier caliper. I'm not sure what to do now.
The sugino mesenger crank I have works with a 103mm axle apparently, but i'm not sure what shell size to get hold of. Do i need to get it refaced?!
-
This bottom bracket shell is now the only thing i am not understanding. I've had the threads checked and they are not 26tpi that raleigh used but, they are 24tpi which was used when carlton was their own company.
All i am unsure of now is what BB to fit. A carlton corsa frame with 120 rear spacing and miche primato track hub (42mm chainline) and sugino messenger cranks. Stated length to use was a 103mm axle.
Being a 71mm BB shell, what approach do i take?!! I can work out everything else with chainline, just not sure which BB will give me the best adjustment. English threads by the way. (sorry if thas obvious)
Once i got this cleared up it's the home straight i think!!!
-
I had a similar thing with one of my lbs. They told me that it's not possible to run fixed on an old threaded freewheel hub. I know it's not strictly the best way to run fixed, but I also know that plenty of people do it and get along fine with it. I went home later that day and change my hub straight to fixed. It works:-D

Hmmm, I've got an old Raleigh frame and accoridng to SheldonBrown if the BB measurement is 71mm or 76mmthen the TPI is 26 not 24, if the BB is 68mm then it's a 24. I guess it may be different with your Carlton frame though as you've had it checked.

What's your chainline like?!? I tried that and was miles out! My LBS still laugh about it... In a nice way...
BTW Round of applause to peahead for not bitching about his LBS (although they probably deserve it) from the get-go... :] -

BTW Round of applause to peahead for not bitching about his LBS (although they probably deserve it) from the get-go... :]It's probably on a couple of mm out. It's pretty close. I'm having to use the inner ring on the chainset that I have, so I'm running 42/16 rather than 52/20. I'm just trying to keep the cost down as low as possible, so all I've bought to convert the bike is:
2nd risers = £5
track cog = £12
lock ring tool = £10 (although not really a cost to the bike as it is a tool that will last forever!
1/8 chain = £9
pedals/cages/straps = £7
pair of blizzrd sport tires = £18 ( got them in Sheffield so they're rather cheaper than London!
Total = £61 (inc. tool)Not bad to completely convert a 22 y.o. Peugeot into a fixie!
p.s. although I could do with some new forks that will allow me to barspin

My local bike shop just shop just told me i cant run fixed because i dont have rear track drop outs. My cartlon has long horizontal drop outs though, so whats the deal!!!?!! Are chain tugs essential?
