Kona Caldera single speed project HELP!!
I don’t have an ebb. I was planning on seeing if I could get the right tension by using different chains and adjusting the length. Is this possible? Even if so, is it risky? If that didn’t work I’d just get a tensioner. I’m trying to keep the costs down as I’m on a budget you see..Posted 4 years ago
I just bought a Kona Caldera frame (2004 model i think) and I’m thinking of building it up as a budget single speed. It’s not ss specific so there is a slot for a derailleur hanger. Seeing as I’m going ss I don’t want the hanger on there but I’m guessing the wheel won’t fit on without it. I’m using a bolt on as opposed to a QR hub. Is there a part available that can fill in this slot without the hanger sticking out or does no such thing exist? Or am I going to have to go DIY and saw it off? Any help would be much appreciated. Thanks in advance!Posted 4 years ago
@breadcrumb Woah that blackspire tensioner looks ace! And I’m curious as to how you neatened the dropout – whats an infill and where do I get one? Btw I’m also planning on using the same Deore crankset as the one in the second pic. How did you find converting it to a single ring? Was it difficult? Did you need shorter chainring bolts?Posted 4 years ago
I made the infill piece from a piece of aluminium, you could trim down a mech hanger or try wanted ad for a broken one?
Dead easy to convert the chainset to a single. Yes you will need shorter chainring bolts, you could file them down though. I’ve used washers in the past too, but it’s only a few quid for shorter bolts from Charlie the bikemonger.Posted 4 years ago
Cheers breadcrumb, I’ll mostly likely order my bolts from there.
I can’t seem to post an image or I would have shown how I’m getting on. Lots of parts arriving soon. Can’t wait to put this thing together and see what all this ‘single speed’ hype is about! My biggest worry is not getting the gear ratio right. Done a little research and think 36×16 would be good for me. I intend to use it as a ‘do-it-all’ bike. I’ll be riding ~ 60% road and 40% trails. Nothing technical though- just local canal-ways and country parks. What do you think? What do you run? I’d appreciate any suggestions!Posted 4 years ago
I ran 32:18 on my Kula (26″), but that was purely trails, and I live next to the Lakes! I’m on a 29er now with the same ratio, bit harder going but still enjoyable.
To be honest, even if you find it too hard on the trails, you could swap the rear sprocket to a 18t and have the 2:1 gearing most folk run anyway. Rear sprockets are only about £4.Posted 4 years ago
