eucarya's Tunturi Build

Inspired by wtfnoob's Bianchi build thread I thought I'd start one for mine. Seemed like something that could help keep me motivated and give me a chance to get input as I build up my first fixed gear. I've got all the same disclaimers as wtfnoob, this is my first build so it's as much educational as it is a chance to build something I can ride.

The frame I'm using is a Tunturi 500r that I picked up for $75. I didn't get a chance to take photos before I started stripping it but here's a few the guy I bought it from took -






I don't have a metric tape measure but the frame is a little over 23" which should translate to about 59cm.

I started stripping the frame last night. My big gripes are the shifter bosses and wirestops, although I have no plans to grind them off now (unless there's a way to do this without repainting the entire frame). The paint job, despite being dirty in the pictures, is still pretty good so it will clean up well for now. I figure that after I build it up if I have a big enough problem with the bosses/stays I'll grind and repaint. Here's a few pics...






As you can see the frame is plain white, for now I'm going to leave the Tunturi decals on but all I'd have to do is slide them off for a somewhat clean look. As you can also see I don't have a chain tool right now so it's lugging around a chain. The drop bars on the bike were crap once the tape came off - 'Sakae Jae Chen Champs' basically generic bars with a separate piece of metal covering the center with the logos stamped. I have some Bridgestone Kabuki bars that I took off a junked Skyway that are in nice condition and have the sick Kabuki-face logo, so I'm going to use these.



As far as my plans for the build. Here's my to do list so far:

+ Replace the bottom bracket - Don't have proper tools so I'm going to take it in to the shop.
+ Wheelset - Looking at a few different options, trying to stay under $200. I need complete set and tires/tubes. Also need cog & lockring.
+ New chain and eventually crank - Going to order a white chain and use the current crank for now (Sakae GXC, although the left arm is a different make/color). Thinking of going with the smaller 42t but my buddy keeps telling me to go with the big ring. So I'm looking at running like 42/15 or so.
+ New pedals/toeclips
+ New seat
+ Install a front break - I've got an old Dyno BMX in my garage I was going to salvage this from
+ Put it all together, clean it up, and ride!

I'll post updates as I progress.

I've done what you're doing more than 3 times. Mine were all schwinns and i loved the result. Later i bought my first track bike and realized how much lighter and faster a complete track bike can be. If you spend more than $250 then you are going too far on your conversion and should consider a track bike. Thats my opinion. That original saddle is kind of cool. I wish they made those still (diamond patterned) and in a light version.

It's taking some time but I'm gradually getting closer to building this bike. I've accumulated some new parts, etc. Here's an update...




I cleaned the frame and fork and got them as sparkly nice as I possibly could. Theres some scuffs and scratches but overall they both look pretty good, especially for being white.

I found out that the arms on the crank I had were beginning to strip a bit so I bought a completely new crank.

Here's a list of new stuff:

Sugino XD 46t / 165mm Crankset - $69
MKS Sylvan Tracks, MKS Toe Clips, Nylon Straps - $33
Alex AT-450/Formula Hub Wheelset - $109
Chain (1/8th, crank is 3/32 but ppls tell me this will work. If it's too noisy I'll just buy a new one) - $8
Brake Cable - $7

and older stuff

Tunturi 500r (using Frame, Fork/Headset, Stem, Seatpost) - $75
Bridgestone Kabuki Dropbars (bought full bike, salvaged bars) - $10
Old School San Marco Diamond Seat (from a friend's bike) - Free

This brings me to around $311 spent so far. That's not including shipping. With shipping probably around $340ish. I ordered all the parts from Ben's. They run a special for pedal sets which gave me the nylon straps for free and then gave me a $20 off coupon that I used toward the wheelset (they run $129). I was going to buy the Mavic/Formula set from BWW but the coupon from Ben's made the Alex's that much cheaper and I figure I won't notice the difference as a fixed gear novice. Plus the AT-450's seem to be one of the better models of Alex Rims and they look pretty slick.

I've got just a few things left to pick up before I can get my hands dirty...

Cog/Lockring - I'm leaning toward either a 16 or 17 cog to use with the 46t XD.
Bottom Bracket - Going to check with the LBS, not trying to spend more than $30 on this though... Ben's has a Tange BB that if it fits I'll go with
Tires/Tubes - LBS
Brake - I have a salvaged BMX brake but it's a right brake, so I might just buy a new one.
& LBS for any other small stuff I find out I need along the way.

All in all I figure I can pick all the remainder stuff for way under $100, so my final tally will be in the $400ish for the project. I know I could have picked up a BD bike for this but this is more fun. Plus I can swap components out if I decide to upgrade down the line.

I'm going to call the LBS tomorrow and check on their stock of cogs and BBs. I'm not 100% sure what width BB I need for this frame but when the guy took out the BB for me he tried to fit a standard Shimano cartridge in and it seems the right width/threading. I'm also not 100% sure on what gearing to start with, I was going to grab Dura-Ace stuff as that seems the cheapest respected manufacturer but that would leave me with 16 being the biggest cog I could get. From what I gather 46/16 would be ok for commuting and maybe a bit high to learn skidding and trackstands but not impossible.

Thanks for the replies so far - I'll post more pics and info, hopefully soon!!!

Bought a 16t Dura-Ace cog/lock-ring off a buddy for 12 bucks
Picked up some 700x25 Continental Ultra Sports and some tubes for around $36
Also got some Cinelli Cork Tape for like $8
and (hopefully) picking up a brake from a buddy if it fits...

& my last part is on it's way -

Sugino 68x103mm BB from Great Britain... Ben's sold out of all their 103mm BBs and I could not find a shop anywhere in the US that stocked the 103mm Sugino BBs for a reasonable price but got it at about 5 bucks more than it would have been from Ben's from an eBay store in the UK.

It's finals week and I've been crazy busy so putting this thing together finally will be a nice end of semestre gift to self. I'll post more pics and a price total once I've (finally) got it built!

Ok so this is finally built! After 2+ months and a lot of help from friends I have my first fixed gear. Still needs a little love though - needs new seat post, seat post clamp, brake pads (probably complete brake), and I've got to wrap the bars tomorrow.

Here's a part/price tally:

Parts from Craigslist, Ben's, LBS, eBay, and Friends...

Tunturi 500r Road Bike, everything stripped but frame/fork/stem/headset/seatpost : $75
Alex AT450/Formula Wheelset: $109
Sugino XD 46t/165mm Crank: $69
Sugino 103mm Bottom Bracket: $38
MKS Sylvan Tracks/MKS Toe Clips/Nylon Straps: $33
Dura-Ace 16t cog & Lockring: $12
San Marco Ponza Seat: $20
Continental Ultra Sport 700x25 & Tubes: $36
Bridgestone Kabuki Dropbars: $10
Chain: $8
Brake Cable: $7
Cinelli Bar Tape: $8
Rim Tape: $4
Forte In-Line Brake Lever: Free

So thus far I've put $429 (not including shipping or misc expenses) into this build and it's finally ridable. I'll post better pictures soon when I've got the bars taped and can get some pretty daylight shots , until then here's a grimy midnight basement shot...

building up a bike is cool and all, but i think you should've gone with a kilo tt pro with the amount you've put in.

Money isn't everything. It sounds like this person has had a great learning experience that money could never buy. Some people value the time spent creating something rather than clicking 'Buy' on some online site. They also were able to reuse some parts and material that otherwise would have had to be mined and assembled by exploited workers.

It sort of looks like you mounted a kick-stand to your spokes...

Great bike!

BD bikes don't really excite me, I'd rather build something up, have fun doing it and have a custom bike. If I want to upgrade the frame later I can get something nicer than anything BD offers and toss my parts on it or start a new build using what I learned from this one but with a track frame. Plus I like the idea of a lugged frame (even if it has bosses) and if I went with a BD bike I'd have to immediately upgrade cog, handlebars, and saddle, plus whatever else I found out while riding it. BD seems like a great deal for someone who needs a decent bike quick but I wanted to build something up from pretty much scratch. The build and customization of an old bike was part of the appeal. There are tons of Kilo's floating around but I've only been able to find one or two other Tunturi conversions on the interweb.

Ps. Thanks for the comments, I'll post some better pics and impressions in the next few days..

Here's a few more pics, been riding this around when the weathers not too bad (got my MTB Commuter for Snow/Rain). Had to add a little strip of bar tape above the shifter bosses as the brake was slamming into the downtube.

Need a new seatpost at some point and allen bolt rather than quick release although it works perfect for riding around and learning basic stuff. Really enjoying the bike so far...








& the obligatory chainline shot

Seatpost is on backwards. Looks good otherwise.

This is my first bike with the old school two piece seatpost (my commuter has the built-in clamp style). Actually had to buy a new seatpost because the one on there was shot and all the LBS had in stock in the right size was another of the blah old school. Wanted to ride ASAP so I bought it and put it together with some difficulty as the clamp was slightly too wide for the bars on the saddle.

In my frustration I must have put it on backwards but is there any particular reason why one way is "right" and the other is "wrong" as far as direction for this style of seatpost? Just curious as the practicality of the direction, I figured the solid part should face backward rather than forward when I put it together. I have to flip the rear tire (put that on backward too ) and tighten the chainline so I'll muddle with the seatpost then.

I believe it just has to do with the fore-aft positioning, as it will tend to move the saddle farther forward, although I suppose it's conceivable there are structural or security (as in how securely the hardware grabs onto the saddle rails) reasons as well, but I am not aware of any.

This bike has undergone some significant changes. Don't have any new pictures right now but the most serious change is that it's out of commission w/ bent wheels.

Flipped over the bars the other day, pulling the bike w/ me and bending both (!) wheels. Both are pretty much destroyed or beyond help. Now I understand why everyone who advocates not skimping advocates thus. Also understand those who advocate wearing a helmet, as seen in the crack in my helmet that could have been in my head.

so...

...lacing the rear hub to a Deep V and running another Alex wheel on the front until I can afford another Deep V which I'll probably just build w/ the front hub. I'll try to post some pics as I do this...

...constantly changing, now: Rear Deep V due to wasting the Alex rim, Random saddle due to bent Ponza, Nitto bullhorns, new tires, etc...

Good to know that there are some people willing to put the money into learning the ins and outs of a bike rather than just buying from bikes direct. Build looks good!

+1 for the drops though

bikesdirect sells framesets too. not to diminish the value of building up a bike, but well... this bike would have been far less expensive and probably nicer to ride were it tuned up and upgraded in its road bike guise. hell, some mavic wheels, a new cassette and dual pivot calipers would have turned this thing into a screamer.

I'd like to know more on how did you get your hands on a Finnish-made bicycle. I mean, how did it find its way into the US of A?
