[RBW] Re: Replace 27 wheels with 700c or 650b? Brakes = Silvers
The brakes I'm looking at cover 79-99 mm, at least according to Amazon's description. I need about 89mm reach so they should work. Amazon lists models 324 and 326 on a search, but the model isn't in the description of the brake I've ordered. Thanks for the offer on the brake, I may contact you offline if what I have on the way doesn't work. If a 27 to 26 conversion is possible with either brake, this could be good news for Riv types on a budget. I'll post the results / pics.

Re: [RBW] Re: Replace 27 wheels with 700c or 650b? Brakes = Silvers
I don't have fenders on my Trek 620 but could fit them around the 38mm pari mottos. I don't think it would work with 41s though. The chain stays are too close. Also those bikes have horizontal drop outs so you would want that spring mount that VO sells.

Re: [RBW] Re: Replace 27 wheels with 700c or 650b? Brakes = Silvers
My Riv Road has very similar clearance to steel Treks and other classic sport touring bikes (on purpose). With a 650b conversion, the limit became the width of the chain stays and fork legs, not the height. I have plenty of extra height for fenders above 650x38b tires, but no width clearance for Hetres. SKS P45's fit great. I improvised a spring mount for the front fender so I can remove the rear wheel (horizontal dropouts). I converted an '84 Raleigh Marathon from 27 to 700c, and it clears a 700x32c tire but would not fit a bigger 700c tire. Considering it was designed for 27 x 1 1.8 (28 mm) tires, that makes sense. There is barely enough space under the brake bridge for a P45 fender. It fits, but tightly, so the fender line is kinda crummy. I also have a pretty minty '85 Trek 420 that I scored for $100. Nice brazing, good looking frame. But mine is too small for me, so I'm gonna sell it to a friend and help him build it up into a tourer. If you want 32mm tires and/or fenders, you should probably go with a 650b conversion. Tektro 559 brakes come in nutted mount versions. If you're ok with 32 mm tires and maybe fenders, then 700c should work fine.

[RBW] Re: Replace 27 wheels with 700c or 650b? Brakes = Silvers
I don't know about the 650b compatibility but I will say that in my opinion if you're a heavier rider it is a waste of time to build a wheel around a freewheel hub. They are by design much weaker than a 130 cassette hub. I weigh 240 and have killed more than a few freewheel hubs by breaking the axle, the weak point of those hubs. You can usually just squeeze a 130 hub in a 126 frame although cold setting is easy and worth it. Good luck with the new frame!

[RBW] Re: Replace 27 wheels with 700c or 650b? Brakes = Silvers
I bought a 1985 Trek 400 earlier this year, and it has become my favorite bike. It looked unused, with just a few marks on the paint from where it was moved around in the garage over the years. According to the 1985 Trek brochure, geometry for the 400 and 420 are the same, and the tubing set is the same. Both came with 27 x 1 1/8 tires and the same DiaCompe brakes, so tire clearance may be similar. I replaced the 27 inch wheelset with 700c. The rear hub is 130 and fits fine as is, no problems. The tires are 33 mm Jack Brown Greens. No way a bigger 700c tire would fit. Pretty tight at the chainstays and even tighter under the fork. I actually tried a Pasela 27 x 1 1/4 first and they were too big. I installed 2 Tektro R365 sidepull brakes from Riv. Both are front recessed brakes. The fork on my 400 is recessed and the rear brake bridge is not, so a few washers on the rear and the brakes worked fine. The 700c wheelset has the brake pads at the top of the slots. A 650b wheelset would probably work with these brakes. Pictures of my Trek 400, with several Riv upgrades, here https://flic.kr/s/aHsjXsYBGU Good luck!

Thanks to everyone SO much for all the helpful info. I never considered that I might be tire height limited with 700c. Guess I'll pursue 650b wheels and see how bigga tires I can squeeze in. My 420 is the 24 frame size so hopefully I can go a little bigger than 38mm.

[RBW] Re: Replace 27 wheels with 700c or 650b? Brakes = Silvers
With a steel frame, you don't really need to cold-set the frame from 126mm to 130mm. My wife recently acquired a 1983 Trek 500 and we modernized the parts and use 130mm OLD ultegra/A23 700c wheels. The frame has 126mm but a gentle tug east-west of the drop-out allows me to pull the rear wheel in easily. Actually, the Silver/Tektro 559 might not work with 700c wheels, unless the reach for 700c on the frameset is longer than 55mm. So you really need to determine the wheel size first before selecting the brakes.

My wife recently acquired a 1983 Trek 500 and we modernized the parts and use 130mm OLD ultegra/A23 700c wheels. The frame has 126mm but a gentle tug east-west of the drop-out allows me to pull the rear wheel in easily. Actually, the Silver/Tektro 559 might not work with 700c wheels, unless the reach for 700c on the frameset is longer than 55mm. So you really need to determine the wheel size first before selecting the brakes. Also, unless you can score brakes that uses nut instead of recessed allen, you will have to drill the frameset to use most recess-allen-equipped brake calipers. I tend to use center-pull brakes for these conversions for easy and inexpensive sourcing, as well as better braking power.

[RBW] Re: Replace 27 wheels with 700c or 650b? Brakes = Silvers
I have a 1984 Trek 620,which I bought after selling a1983 Trek 620. The 84 model was specd with 27 wheels and canti brakes set just at 57 mm drop. I first converted to 700C and found that I could barely fit a 30 mm tire (actual) and fenders. I ground out some metal at the bottom of the crown to make it work. I did spread the stays to 130 mm. No problem. I really like the way the frame handled and responded. Beautiful. I found the ride responsive and didn't want to let go of it. So I had it repaired and the studs repositioned for 650 B, along with SS couplers. Now I ride it with 38mm Pari Moto tires and absolutely love it. A good ride is better than a vintage show piece. I think the 420 is one level down in steel and components (now probably long since gone) but I'll bet that good Reynolds standard gauge steel still performs wonderfully. I'd say go for a modernization. Spread to 130, easy. Convert to 650B. A bargain compared to any new, comparable frame. michael On Thursday, August 28, 2014 8:03:39 PM UTC-4, cbone97 wrote: So after selling my Sam (sniff sniff), I scored a 1985 Trek 420 with 27 wheels.

This really makes me ponder converting my Trek to 650B. Man, I was so close to having one wheel size for my bikes!

[RBW] Re: Replace 27 wheels with 700c or 650b? Brakes = Silvers
I converted a 1984 Trek 500 to from 27 to 650 a few years ago. Was able to fit 650 x 38 tires, I don't think I would have had clearance for anything larger. I believe that was also a 126mm hub and I had no problem sliding a 130mm hub in there. There was just enough reach on the brakes with the Tektro long reach brakes. No issue with the bottom bracket difference. I liked that setup a lot. Sold it to my brother though. Looks like the vintage-trek.com site is down, hope its temporary. If I ever doe another 650b conversion I'll look for a similar trek bike. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Were you able to fit fenders with those 650 x 38 tires? On Aug 28, 2014, at 11:03 PM, DS davecst...@gmail.com wrote: I converted a 1984 Trek 500 to from 27 to 650 a few years ago.
