Thinking about belt drive.....

So,

With the single speed MTB built, I am not looking at a Gates Carbon drive system. Looks fairly easy to install (for the mechanically minded) - depends on costs. Anyone know of a uk distributor/prices or done anything similiar?

    Don't know about UK, I've only dealt with Germany after I snapped a belt (LBS had over tensioned). The distributor replaced the belt free of charge.

    I love my belt in the winter.

    So, who's going to cut the rear triangle, you or the LBS? That's got to be the most nervous part

    Fixie Inc are really helpful but Gates will also deal direct.

    Ha! And you thought you had overspent already! You really need a titanium frame now too.

    I have mailed Gates in Germany - nothing back yet. I think it will cost a bob or two....

    @Wrath Rob, I will do the job myself. I think that no LBS would take on the work aside Argos Cycles in Bristol or Bob Jackson in Leeds.

    The good old angle grinder with a slim disk will sort, but I will probably use the trusty hack saw.

    Quite happy with the procedure for fitting a belt drive. Not sure I can live with the cost, however, after blow-out this weekend on a trail with junior strapped to the bike - I can live without the chain oil getting everywhere!

    Now, Where is my thomson seatpost, Xc282 bars and XT crankset.....? :-)

    Hi Buddy,

    From Fixie Inc last summer when I converted mine;

    We can offer the rear hub we use in the Paecemaker bike seperately (currently brown anodized only, 119,- EUR). The front spocket 55T 130BCD is at 119,- EUR, the rear Multipulley can handle fixed/free and is available as 20/21/22T at 79,- EUR

    I've also got the full, from Gates direct, price list on a spreadsheet (well, November last year anyway) PM me an email address and I'll mail it over to you if you want.

    Hmm - Got quoted £205

    46T front pulley 104BCD
    25T Sprocket
    113T belt

    Thats allot of cash for chain, front ring and sprocket!!!!

    It is for a mountain bike, most singlespeed MTBs are 32 x 18 - 1.8:1 ratio.....

    I may go with a 24T rear though, just to be different.....

    It will be for mountains and singletrack.

    Aha, makes sense then.

    And the bike has a junior seat on it sometimes - so, an extra 15kg!

    surely the answer is to use wax lube ? this way the chain is dry lubed and does't get oily stain hell, you just keep it washed and keep applying fresh lube over the top of the existing stuff

    used to use that on motorbike chains, still messy sh1te and I believe that the belt drive clears mud more efficiently.

    I am talking myself into it.....

    @simonah - do you have any metal working gear that can cut and form stainless steel?
  • SimonAHSimonAH Posts: 3,730
    I do, to a level. What are you thinking of?

    Stainless steel insert for the dropout, I was gonna wing it with an angle grinder, but would rather make a decent job of it!

    Basically a "U" shaped piece to fit over the dropout.

    Not sure on my tap and die kit either.....I don't think it is man enough to thread holes made in a dropout.....

    Also considering pillar drill to drill dropout rather than electric drill!

    Hmmmm - stlll, pickin up XT cranks and BB on Thurs night!

    very interesting project, very evil one too :twisted:

    i like the belt drive idea alot. was hoping a mtb with belt come out on the market soon. didnt think of to convert one into it.

    Sweet! Do you have access to CNC or milling machine?
  • rjsterryrjsterry Posts: 18,008
    A friend who built his own SS DH bike from scratch, bought himself a pillar drill for the dropouts IIRC. No real experience of metalwork, but I would think that you definitely want everything plumb and square to avoid problems later.

    Here's my friend's blog

    Chuff me! They want £1450 for their commuter bike at a minimum! I also love their use of the term "Aricraft-grade 4130 chromoly steel", do they make planes out of steel? :lol:
  • gtvlussogtvlusso Posts: 5,112
    LOL! Brand and # of bottles please!

    I guess you would need an engineering drawing of the part?
  • SimonAHSimonAH Posts: 3,730
    Yeah, a drawing would be good. PM me with what you have when you're ready.

    4130 Chromo is fairly standard middle of the road stuff. They might use it for some bits of aircraft, but to describe it as aircraft-grade is overselling it a wee bit.

    But that's actually what it's called in the trade. 4130 comes in "aircraft" grade or "commercial" grade. Many small aircraft have fuselages constructed entirely out of the stuff, because it's cheap, strong and easily welded, and apparently not too heavy even for a single-engined plane. Here's an example:

    I have noticed, when looking online for gates carbon drive parts, that they vary wildly in price... I replaced my rear pulley a while ago, and bought it at universal cycles, they shipped to Europe, and it was cheaper this way than anyplace I could find it in Europe.

    But yeah, this stuff is very expensive, presumably partially because there is such a small market.

    http://www.universalcycles.com/search.p ... tes+carbon

    113t belt: USD 53
    104 BCD 46t front sprocket: USD 118
    25t rear sprocket USD 119
    USD 290 in all, about £180

    the 24t rear pulley is USD 50 cheaper than the 25t!

    Try direct to Gates, I can PM you the contact details too if that would help.
