Re: frame sizing question Posted: Thu Feb 17, 2005 9:42 am boogenman Kingpin   Joined: Sep 17, 2003 Posts: 2444 Location: Amherst, NY The Geo on that frame sucks for trials, a 14" isn't small unless you are over 6' go to trialsin.com and see if they have anything, even better would be to call him up and ask. Here is a tip for a new stock trials rider, buy a good rear hub that engages quickly Posted: Thu Feb 17, 2005 2:33 pm bowhers All-City   Joined: Aug 24, 2004 Posts: 931 Buy trials specific, 10 years ago the Azonic frames were still bad for trials. The BB is like 10 inches high whereas many trials bikes today have a plus 20 mm. Following parts need to not be skipped out on: Rear hub brakes (if going for V anything without parrallel push mechanisms) cranks (buy nice off the back its not worth it otherwise...) If you have any trials questions PM me or continue the thread, If you are looking for a nice trials bike with a seat I would check out a few of Echo's offerings, Planet X has some nice stuff too if you can find a Zebdi, the Tibo and the new Alibongo are also really nice options. _________________ NL Bikes Re: frame sizing question Posted: Thu Feb 17, 2005 2:56 pm rpl3000 Bomber   Joined: Nov 15, 2004 Posts: 51 Location: haddam, ct i'm looking for a stock bike with a seat so i can still cruise around on it. that way i can atleast make it into a 24" park bike if i decide trials isnt my thing. i ride a P1 now and i can hop a bit on the back wheel and to tiny pedal kicks foreward. i've hear of people ripping off the disk mount tabs doing this so i've been wary. plus the gear on it is too low and its got a 5" DJ3. not exactly suited for trials. webcyclery has a complete planet-x zebdi for 900$ in the specs it says- LX silent clutch wheel SRAM 5.0 brakes Truvativ crank i can imagine that with any entry level bike that hub is garbage and would probably need replacing within a few months. as for the brakes i have no idea. i swore off v-brakes a few years ago and if i really get into it i'll go HS-33. I have a question about mounting HS-33's. i noticed that some forks and frames have 4 bolt mounts specific for these brakes. can you mount them on a frame with regular v-brake mounts? also, i think i'd like to run an 80mm suspension fork because i'm a hack and i'm 6 weeks post surgery on a torn ligament in my wrist. not that i'll be jumping anytime soon but i think i'd like to start with a bit of cusion up front. one more question. when i read about frame specs some say 0-BB and others say +20mm BB. what does this mean? BB height in relation to the rear axle? Thanks. _________________ unemployed. anyone need a mechanical engineer? PM me. Posted: Thu Feb 17, 2005 7:07 pm bowhers All-City   Joined: Aug 24, 2004 Posts: 931 Ok let me do my best and hopefully give you some good ideas. First I would build my own bike especially if you are a rider from another discipline. It will give you the best bargain. I would go V's they work really well and discs will cause you some serious pain if you wan tto run them in the back. You will go through calipers, adapters, and then frames. The WC Zebdi wouldnt be HORRIBLE, but yeah you will end up killing particular parts off rather quickly. HS 33s have "evolution adapters" which allow you to run them onto bikes without 4 bolt mounts. Maggies are way more money then a really good set of V's, If cash is tight get V's. My personal brake of choice is the Avid Sd 7 caliper with XTR levers. Xtr levers are awesome and would really get them over anything else. If you run an 80 mm fork on the Zebdi it will feel weird. I did that and yeah, it sucked. The Zebdi is designed around a 400 mm fork. I would say if you are worrying about maybe not getting TOO into trials and you really wanna run that suspension fork do yourself a favor and get the Planet X Jackflash. Stronger then the ebdi, built around a slightly taller fork, geo would actually work for dirt jumping. _________________ NL Bikes Re: frame sizing question Posted: Thu Feb 17, 2005 7:27 pm Geoff All-City   Joined: Sep 7, 2002 Posts: 844 Location: CT if your looking for a small cheap frame to learn on, i've got a 12.5" frame i'll sell you w/ xt bb, fsa headset and rigid fork for $50 ... not a trials specific frame, but it was good enough for me to win sport class comps on. Re: frame sizing question Posted: Thu Feb 17, 2005 10:34 pm rpl3000 Bomber   Joined: Nov 15, 2004 Posts: 51 Location: haddam, ct Bowhers, thanks for the info. it doesnt seem like such a good think after all. plus i remember when i got my P1 i busted like 200$ worth of parts in about a month. they really skimp on components to get the prices of entry -level completes down. if i find out this is something i'd want to pursue then its not the right frame to build off of anyway. I'm not going to buy or build a new bike for atleast another month or two. i'm just trying to learn about the sport a bit before i get anything. like the fixed cog rear hubs and the freewheel on the crank arm set up is pretty slick. geoff, yea i'll definatly have a look. where in CT are you? maybe we can set something up next week. its 26" right? if it isnt then I dont have a front wheel for it. also any other extra parts you feel like parting with to get me started i'd be happy to consider. if you feel its got the geometry for a starter then it sounds good to me. if i really like trials then i'm going to end up getting something in april or may anyway so it really would just be a starter bike. i'll have to build up a rear wheel though. think a rhino lite XL will do for a start? 29mm wide. i've got a spare specialized SS nutted hub that was stock on the '03 P1's. i dont know how quick it engages but its got cartridge bearings and a solid axle. i have a front wheel, old avid single digit 7 V's and a ton of square taper cranks arms so maybe i could be rolling in 2-3weeks for under 200 bones. sweet! also Bowers do you still have some of the parts listed in the buy sell? i was gonna canibalize the P1 for parts but if i can keep that intact then i dont care if the frame is dual use or not. _________________ unemployed. anyone need a mechanical engineer?

Posted: Fri Feb 18, 2005 4:02 pm bowhers All-City   Joined: Aug 24, 2004 Posts: 931 I have a bunch of parts and a frame, but I might keep the frame as a back up since my sponsors are in England, it takes a long time to get new stuff. I would also stay away from real specific parts like front freewheel cranks and such, they wont be useable on anything else... The specialzed hub will last you about 6 months tops once you learn to pedal kick. _________________ NL Bikes Re: frame sizing question Posted: Fri Feb 18, 2005 5:10 pm rpl3000 Bomber   Joined: Nov 15, 2004 Posts: 51 Location: haddam, ct yea i'm not looking into the specalized stuff but its definatly cool. as soon as i get in touch with geoff about a frame i'll be sure to see what you have for parts to get me started. thanks. _________________ unemployed. anyone need a mechanical engineer?
