So its that time again when my mordern bike gets a revamp.
This year its the frame!! and i've decided to go Ti custom!!
I'm 5'10" and always found sizing difficult, its either an xc friendly 18" or a 'play bike' friendly 16" (yes i could go 17" but then choice is limited). Ireally like the extra standover hight an 'wippyness' of 16" frames - the last 4 bikes have been 16's, but the downside is climbing ability. I've got around this in the past by running 90 or 100mm stems but then the steering is slow and i loose the advantage of having a small frame so its not ideal.
The idea is to build a 16" frame with an equivilent to an 18" toptube. Which sound like my perfect 'do it all bike', one i'll keep for years.
Only down side is i can't afford the realms of Lynskey, IF etc. so i'm going to China
Well, no actually going, morelike ordering. From Xacd.com.cn to be exact. I've heard and seen good things from them and had enough email conversations with them over the last 2 weeks to feel confident enough to order.
If you've not heard of Xacd (they're more well known in Road circles) before heres a couple of web sites that'll give you an idea of the stuff they have produced for people in the past:
They're own web site is not that great, but there are some interesting examples on there (some good, some, well interesting).
So next step geometry....
after a couple of revisions heres what i've come up with:
Head Angle 70
Fork Offset (Rake) 43mm
Chainstay Length 425mm
Seat Tube Angle 73
Horizontal Top Tube Length 564
Effective Top Tube Length 589 (23.25" or equivalent to an 18" xc bike)
Bottom Bracket Drop 305mm
BB height is quite low (normal xc bike would be around 310-315 i guess), but i'd like it to be quite stable and fun to ride, i generally run 170mm chainset so 5 mm lower sounds like a good idea.
I sent these specs over to Xacd and heres the Cad drawing they've come back with:
This is the second drawing they've done for me and have been great in comunication, the drawings being emailed over within 24hrs. The low standover and toptube/seattube brace is a must (although added extra cost) and i've also added the bend in the down tube (at request, and extra cost) to
aid fork clearence.
Final thing the cost, which is the hard part as i still need to raise the funds (and get them past the wife)....
£550 ish posted. delivery time less than 4 weeks.
So what are your thoughts?
