Chain Tug on converted road frame

Would it work?? we're talking semi-horizontal forward facing d/o's here, just an idea as they still have something to pull against dont they?

i knew i had heard of them but had not seen them before.

The guys at bmx-onlineshop.de have developed chaintugs that also work on forward-facing drops. The description is in german, but I have mailed them in english before and they are more than willing to help. So if you have questions, just mail them.

(Just to be perfectly clear: I have no connection to them, having seen this chaitug on their page I thought it was revelvant to post it)

sorted! i'll go now.

you can get that exact pair on ebay for like 4 quid, i've got a set on my bike and they seem to be pretty good. had em on about a month now, no snappage. Haven't tried them on a forward facing dropouts though

says it works both ways, facing forward and backward dropouts. if facing forward than you mount it on the loop at the back, spanner screws goes along the outside of the dropout, hope that makes sense, marc

BMX chain tensioners

I've used these before and they worked fine.
You have to file down the relief part that normally sits in a rear facing drop out though. It took all of about two minutes and then you have a strong, cheap, though ugly tensioner. I would say though that they are quite thick so you have to have a bit of extra length on the axle (I was using Goldtecs which are bolt on so that matters less)

I tried ordering some of the Batavus ones but I didn't get a reply from the Dutch or UK supplier so I decided to make my own, it was relatively simple. I cut the template from a 2mm sheet of aluminum and used a nice brass thumb screw with lock nut to tension, I only made one and it works perfectly on its own. See the pics

5 Attachments

im going to make one of these tommorow.

tristoo- how did you attach the nut to the tug? is it just held in dry with the two tabs? i guess it doesnt really matter as the nut will be held on once the screw is in.

The square backing nut is snugly held in place by the 2 tabs, but also the long wings too, it only needs to be held in tightly enough not to twist really.

@ Tristoo - That's a seriously nice job you've done there, I'm not in need of one but you could turn a pretty penny on those.

In a panic to have something ready for the weekend i got this off ebay for about a fiver.

Ten minutes of filing allowed it to sit flush against the drop-out.

Looks a little tacky but Works perfectly.

There you go. Perfectly executed.

You can still pick up old Cyclo Chain tensioners at bike jumbles for forward facing dropouts.

That is a great job on the ones you have made Tristoo

Hey tristoo, yours are looking damn good... if it's ok to give a little constructive criticism..

it might be nice to have a slightly wider area around the wheel nut just to give a nice consistent footprint onto the drop-out. I love the minimal look though.

If you do ever decide to go into production be sure to let me know.

tristoo, i too would be interested in your homemade chain tug.

seriously. fancy making a couple for sale?

Since making that tug I've had quite a bit if interest in it so I'm going to make a few in the workshop to sell, I've done few more prototypes to get the sizing right and taken into consideration a slightly wider area around the wheel nut to give a nice consistent footprint onto the drop-out. They will be made fully stainless steel, I'll have them ready in about a week or so, I'll Pm those who show interest andput a post up too

I'd definately be interested in one of your fine tugs tristoo :)

yeah im interested

Yep, I'd probably be interested too. Any idea on price?
