You should be able to get the flat washers on ebay or have your LBS order them. **Q: Are these stem shifters or downtube shifters** A: Hi...these are downtube shifters. **Q: What clamp can these be used with?** A: These are intended to be used on a frame with brazed-on down-tube fittings. I'm not aware of any adapter clamps for them. **Q: can these be used for a six speed cassette (80's 12 speed bike) and are they index or friction?** A: I upgraded from 6 speed to 8 speed when I bought this so I don’t know. Rear shifter is definitely indexed so that may be an issue. Front shifter is friction. Works well though. ## Customer Reviews ### ⭐⭐⭐⭐⭐ If you want 'em and can find 'em, get 'em *by S***. on April 15, 2011* I put these on my commuter bike for the old-school downtube shifter vibe. Also I'm running a disc brake up front and v-brake on the back, and I didn't want to deal with finding shifters with linear pull brakes for road bike handlebars.I've used these for 6 months and they're built solid. For anyone new to downtube shifters, just be wary: they require a bit more work than shifters on handlebars but there is a certain simplicity about them that can't be beat. After a few rides, shifting with these feels very natural.The indexing works well. I have no complaints about their function and workmanship. Quite the contrary.At the time that I got them, Shimano was no longer making them, so if you want them and can find them, snap them up. You won't be disappointed. ### ⭐⭐⭐⭐⭐ These are a great choice for a classic bike that has the braze-ons *by B***R on December 10, 2015* These are a great choice for a classic bike that has the braze-ons, beautiful Shimano shifters with indexing on the right side where you need it. Great quality like almost anything Shimano, easy to install and adjust. After 12 years of running modern indexed STI brifters on a traditional lugged steel bike, I decided to simplify and unclutter the handlebars with a set of Shimano aero brake levers and downtube shifters. I purchased both from BikeZilla, and they provided great pricing, speedy delivery service, and the items arrived in original packaging with all instructions and small parts included. I also like the fact that they stock items like this that are not so easy to find. BikeZiIla has been great to do business with. I have had a couple of issues with other Amazon bike parts suppliers who seem to think it is okay to advertise parts as new but then to ship loose parts, or even used parts, removed from the original packaging and missing the small parts and instructions needed for proper installation. Then getting it made right can be a real pain. Amazon really needs to police this more closely. ### ⭐⭐⭐⭐ a bike builder's two cents *by A***S on August 2, 2011* I used these as part of a flat bar conversion project on my wife's old Trek road bike. She has the Shimano RS deraileurs circa 1993. Three gears in the front and 7 in the back. Standard SIS spacing on the rear gearset.The shifters are nice quality, well machined, and have a nice feel.The front shifter has plenty of travel to handle the triple gearset. Getting in and out of granny gear and high gear is easy. There's a little clicky feel like a ratchet in the front shifter but it's not indexed, it's just for friction. Overall it's a nice feel for shifting.The rear shifter is indexed for Shimano 8-speed SIS. I was a little worried about this as my wife's bike has the old 7-speed rear gearset. No worries though. I set little gear as one, and set my deraileur limiter setscrew for the top gear and it shifts just fine. Gears 1-7 click in with precision. Unlike the Dura-Ace shifters, the R400 rear shifter does not have a friction setting. It's set for index shifting and that's all there is. But it does work for either 7 or 8 speed so it's all good. If you really want friction setting, spend the extra $20 and get the Dura-Ace shifters. Re-machining these to get friction is possible, I looked at it, but it might ruin them and I chickened out. As it turns out, my wife loved the index shifting anyway.So they're nice shifters. They're really well made and have a nice feel. ## Frequently Bought Together - Shimano Sora SL-R400 Downtube 8spd Shifter Set SP-3300 Braze-On for Steel Frame - SHIMANO Universal Standard Brake Cable Set, For MTB or Road Bikes - Shimano BL-R400 Road Drop Brake Levers Set (Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/10189530-sora-sl-r400-downtube-8spd-shifter-set-sp-3300-braze](https://www.desertcart.hr/products/10189530-sora-sl-r400-downtube-8spd-shifter-set-sp-3300-braze) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-31*
