My new bike- Centurion Tour Pro 15 speed - now a 21 speed

Well I found this Centurion 15 speed in a basement and have brought it back from the dead. what an amazing bike and can't wait to put some miles on it. I have replaced all cables, housing and pads.
When I got it it had almost all OG parts on it. also here is a link

https://sheldonbrown.com/centurion198...0pro-tour.html




these are its new wheels, got them on craigslist last night. they came with tubes and tires and a 7 speed rear.700C these things are brand new and have never even been on a bike. $90 cash money.
picked up a new chain and got it all tuned up with the new rear wheel,,,shifts smooth

Look who got a 21 speed now baby.lol



My question is that I wanna put V-brakes on this bike and it has posts on the front and back.
can I just use short arm mountain bike v-arms? or what would you use?
Also with these levers should I go with a side pull or a center pull v brake caliper? thanks

Check out this rear wheel lock, even has the key

Those locks are pretty common in Europe esp. the Netherlands; you don't see them often in the States. I'm not sure I understand your question about the brakes. The levers can be used either with centerpulls or sidepulls. You have centerpulls on the bike; are you looking to swap them out? Why? You can now pick up good quality center pulls again and they work well with a long reach like this bike has.

Nice bike and great score.

thanks, the calipers on it now are center pull and mounted on the sides on posts not in the middle top. I was wanting to put mountain bike v brake arms on instead.

(You can now pick up good quality center pulls again and they work well with a long reach like this bike has). can you post a link to post mounted road brakes? thanks

These are what I was thinking of: https://store.velo-orange.com/index.p...ull-brake.html

Your brakes are screwed onto posts on the frame right and not just through a center pull? I don't know if I've seen that before; you should be able to run a center pull as long as the arms clear the posts and spacers can help you out there. Centerpulls are good brakes when you have a long reach.

Thanks for the link, that would work, but still looking for single arms like on a mountain bike...


I dont mind center pull at all, just looking to replace these with newer and better calipers. there is also no hole in the frame or fort to except a single middle bolt to mount.

Also these: https://www.rivbike.com/product-p/brcp1.htm

If there are no mounts on the forks or chainstays, then the bike is not designed for cantis. That was not unusual is an older touring bike. What you need to do is to measure the reach of the brake (from the center bolt to the wheel rim); that will tell you which brakes can work. I'd keep the style and stay with the center pulls.

Got it, no center hole in your fork or in the rear; the mounting posts are actually a good thing: https://velo-orange.blogspot.com/2006...are-swell.html. Plus you have brakes that work. They look to be dia compes which were pretty common back in the day. I'd use 'em and get a better brake pad if you need one. You can hunt around for similar brakes to rob for small parts if need be. Plus it wouldn't surprise me if the "modern" dia compe that rivendell sells would work; you could always give them a call and ask. https://www.rivbike.com/product-p/brcp1.htm

Ring lock better have the key , you need it in there, lock open, to have the wheel turn ,

to take the key out , you have to close the lock .. dont lose the key , bike wont roll..

that all 3 on one 110 BCD bolt means no smaller than 34t chainring.
that's compact double territory these days..

best you can do is a 1:1 low , 34:34..

IRD triple-izer is a 34t ring with a 74mm bolt circle on it to bolt on the 'granny' to it.
to continue using your stuff or get a 110/74mm BCD crankset

the center pulls with KS continental pads should be fine..


your alternatives : side pull types, or a kludge: BMX V brake adapters
and v brakes and levers

How bottomless is the Wallet to pay for a lot of up-mods?

Fietsbob, I have the new wheels installed on the bike and diled in amazing with the rear derailer .I have all gears front and back. using shimano 600 friction down tube shifters. shifts smooth as silk.

have installed new pads on the comps and stops ok but looking for a little more stop fast..lol

as it is the bike is completed, and rides amazing, will keep my eye out for new cranks and what not as I am a 2nd hand bike builder.
