Looking at your photo, I guessed that the FW was not original - it’s not big enough. Your current FW won’t act as a half step. I have the exact same crank setup but use a different 5s FW. Yours is in orange, mine is in green:



To understand these charts, one must have a basic understanding of a half step setup. The step between FW sprockets should be twice the step between chainrings. This allows each step in the FW to be split in half by a concurrent shift up front (a double shift).

I have used gear ratios under each chainring, not inches. Second, the percents represent the amount of change between gears when one double shifts. The firth column, K, represents the deviation of a double shift (both FW and chainring) from a single shift (chainring only - in this case, 11.1%). Ideally you want a 0% deviation, but that’s not possible. To evaluate the efficiency of a half step setup, I then find the sum of the absolute values of the %deviation. The lower the number, the closer the setup is to ideal. I have not yet found a more ideal setup than a 50/45 and this particular 5s 14-32 FW.

Probably way more math than you wanted this early, but there it is. If anyone wants the spreadsheet, I’d be happy to share. One can also more visually see the steps on the HTML5 gear calculator website: https://www.gear-calculator.com

The '82 catalog lists the 14-16-19-23-27-30 freewheel as stock for the 614. Probably would have benefitted from a xxxx-28-32 at the large end, but that would probably have required a longer FW cage.

Good research on your part, bad research on Trek’s part. They should have been more familiar with slide rules!

Thank you for this, Dave. Very informative. Would you mind sending over the spreadsheet? I’d like to play around with it a bit.

Looks like I’ll be switching up my gearing some, I should be able to make a nice setup. Using gear-calculator to help visualize, looks like buying a 48t ring and moving my 13-28 from the 760 should make for nice steps.

Just picked up one of the CR18 wheelsets from Velomine, I’ll pick those up on the way home.

Edit: Harris Cyclery also has Nitto’s “Mark’s Rack” on closeout for $99.95. I’ve been eyeing those anyway, had to nab one yesterday.

I upsized my 610! I swapped an ‘84 22.5” 610 and an ‘86 560 for this long legged and prestine 24” 610! I loved the bike in 22.5 and it’s only better in the right size!

Thanks for that. Just ordered one along with a Nitto seatpost that I "needed" to get free shipping.

Thanks to Shrevvy, another Trek added to the stable. Going to be fun comparing it to the 760.

Itll be receiving Shimano 6207/6208.

My 1982 412. The frame is from Craigslist, the drivetrain is entirely from the co-op and the cockpit is mostly new bits. The frame is nothing special, but I like the build and it makes for a great brevet bike on a budget.

- 1982 Trek 412
- Nitto Noodles wrapped in Brooks microfiber tape. Nitto technomic stem
- Gilles Berthoud Aspen Open atop a VO long set back post
- NGC500 calipers and kool stop salmon inserts paired with new Gran Compe aero levers
- Sugino XD 48-36-24 triple stripped and polished on a Tange bottom bracket
- Shimano XT m735 rear and Deore front derailleur. Ultegra 12-27 cassette shifted by 9 speed Shimano bar ends
- 36h Velocity Dyads laced to White Industries MI5 hubs. DT Swiss competition spokes. VO faceted fenders
- Avocet quill pedals, straps and cages
- Nitto m18 front rack

[MENTION=360414]fliplap[/MENTION] that is a stunning 412! Proper 25.5" size and everything. My '80 412 with the same tubing etc is such a nice rider. Plenty capable, classy, with great ride and road manners. Ace fender line work there, as well as color matching the saddle and bar tape.

Beautiful.

What bags did you choose? Is the front stable without a decaleur?

I made the bags. That front bag has stiffeners on 5 sides, velcro on the bottom and a tombstone loop, so it's really solid, but it's also only 6" tall. I made it for fair weather events and it isn't big enough for a ride where I'd need more layers, or an unsupported 600km. I'll likely need a decaleur for its incoming, taller, pocket-i-er, replacement.

Oh, and in case anyone was wondering, those are 700x32mm Panaracer Paselas. The frame will just barely clear 700x38 Voyager Hypers without fenders. Chain stay clearance is the limiting factor, dimpling would make them clear with flying colors.

Here's my Emonda. Only thing that are still original on it are the handlebar, frame and fork. Everything else has been upgraded and changed. In a few short weeks, I plan to replace the handlebar too. But I do love this beauty.

I've shared this build in another thread, but I am excited about finishing this project (for now) and I want to show it off. It's a 1984 Trek 510 with a 2x10 Shimano Deore XT drivetrain of varying vintages and Tourney centerpulls to maximize fender and tire clearance.
Eventually the plan is to get a Brooks Swallow and hang my Carradice on the back for some long rides. I'll also try out a Dia-Compe centerpull-mounted rack for a randonneur bag. The bartape came from the Box o' Crap and was actually an inspiration for the build, so far I like it a lot.
